Electrolytic manganese slag (EMR) is a solid waste generated in the manganese hydrometallurgy process. It not only takes up significant land space but also contains Mn2+, which can lead to environmental contamination. There is a need for research on the treatment and utilization of EMR. Improved EMR substrate for Pennisetum sinese Roxb growth was determined in pot planting experiments. The study tested the effects of leaching solution, microorganisms, leaf cell structures, and growth data. Results indicated a substrate of 45% EMR, 40% phosphogypsum, 5% Hericium erinaceus fungi residue, 5% quicklime, and 5% dolomite sand significantly increased the available phosphorus content (135.54 ± 2.88 μg·g−1) by 17.95 times, compared to pure soil, and enhanced the relative abundance of dominant bacteria. After 240 days, the plant height (147.00 ± 0.52 cm), number of tillers (6), and aerial dry weight (144.00 ± 15.99g) of Pennisetum sinese Roxb increased by 5.81%, 200%, and 32.58%, respectively. Analyses of leaves and leaching solution revealed that the highest leaf Mn content (46.84 ± 2.91 μg·g−1) being 3.38 times higher than in pure soil, and the leaching solution Mn content (0.66 ± 0.13 μg·g−1) was lowest. Our study suggested P. sinese Roxb grown in an improved EMR substrate could be a feasible option for solidification treatment and resource utilization of EMR. HIGHLIGHTS: The waste solid resource utilization was achieved. The growth and ecological restoration value of Pennisetum sinese Roxb in an improved EMR substrate was found. An optimal ratio of improved EMR substrate was proposed. [ABSTRACT FROM AUTHOR]

BACKGROUND: Lactic acid bacteria (LAB) fermentation technology has been increasingly used in the deep processing of edible fungi. However, the flavor profiles of edible fungi products after mixed LAB fermentation have received less attention and how aromas changes during the mixed LAB fermentation are still open questions. In the present study, fermented Hericium erinaceus and Tremella fuciformis compound juice (FHTJ) was prepared by mixed LAB strains. We aimed to systematically monitor the dynamic changes of aromas and precursors throughout the fermentation process and a data‐driven association network analysis was used to tentatively illustrate the mechanisms of formation between aromas and their precursors. RESULTS: Mixed LAB fermentation could enrich the aroma profile of FHTJ, reducing the unpleasant flavors such as nonanal and 1‐octen‐3‐ol, as well as increasing the floral flavors such as ethyl acetate and α‐pinene. Partial least squares‐discriminant analysis and relative odor activity values revealed that 11 volatile chemicals were recognized as aroma‐active markers. Volcano plot analysis showed that 3‐octen‐2‐one (green flavor) was the key aroma‐active marker in each stage, which was down‐regulated in fermentation stages I, II and IV, whereas it was up‐regulated in stage III. 3‐Octen‐2‐one was significantly negatively correlated with organic acids, particularly pyruvate (r2 = −0.89). Ethyl caprylate (floral flavor) was up‐regulated in the late fermentation stage, and showed a negative correlation with sugar alcohols and a positive correlation with organic acids, especially tartaric acid (r2 = 0.96). CONCLUSION: The present study demonstrates the beneficial effect of mixed LAB fermentation on flavor characteristics, providing guidance for fermented edible fungi juice flavor quality monitoring and control. © 2024 Society of Chemical Industry.

A total of twelve previously unreported isoindolin-1-one compounds, erinacenones A–L (1–12), were isolated from liquid cultures of the medicinal fungus Hericium erinaceus. Their structures were elucidated based on spectroscopic data analysis. The absolute configuration of 12 was determined by comparing its optical rotations with values reported in the literature. The most distinctive feature of these compounds is that their nitrogen atoms are connected to different parts of the special structure moieties. Among them, compounds 3 and 4, as well as 10 and 11, are two pairs of isomers differing only by a small change in the position of one double bond. Compounds 4 and 5 were found to show cytotoxic activities, with IC50 values of 24.7 and 18.4 μM, respectively, against MCF-7 cell lines. [ABSTRACT FROM AUTHOR]

This study evaluated natural extracts from plant biomass for UV protection and oxidative stress reduction. Conducted in Bucharest, Romania, it focused on medicinal mushrooms and pomegranate bark. The biotechnological process involved a two-phase extraction: hot water processing of Ganoderma lucidum, Hericium erinaceus, Inonotus obliquus, and Tremella mushrooms, followed by ethanol extraction with pomegranate bark and green tea. The spectrophotometric analysis identified phenolics and flavonoids. The ethanol extract showed higher phenolic content and antioxidant activity, particularly in DPPH radical scavenging. UVB exposure tests demonstrated its protective effect, comparable to vitamin B3, delaying oxidative stress onset by 30 min. This research underscores the potential of using natural biomass extracts in skincare, promoting environmental sustainability and economic viability by converting agricultural waste into valuable bioactive compounds.

Corn husk, a by-product of corn starch production and processing, contains high-quality dietary fiber (DF). Our study compares and analyzes the impact of Hericium erinaceus solid-state fermentation (SSF) on the structure and physicochemical characteristics of soluble dietary fiber (SDF) of corn husks. The study also investigates the kinetics of SSF of H. erinaceus in this process. The scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) results revealed significant structural changes in corn husk SDF before and after fermentation, with a significant elevation in the functional group numbers. The data indicate that the fermented corn husk SDF's water-holding, swelling, and oil-holding capacities increased to 1.57, 1.95, and 1.80 times those of the pre-fermentation SDF, respectively. Additionally, the results suggest that changes in extracellular enzyme activity and nutrient composition during SSF of H. erinaceus are closely associated with the mycelium growth stage, with a mutual promotion or inhibition relationship between the two. Our study offers a foundation for corn husk SDF fermentation and is relevant to the bioconversion of maize processing by-products. [ABSTRACT FROM AUTHOR]

Social dysfunctions are common in various psychiatric disorders, including depression, schizophrenia, and autism, and are long‐lasting and difficult to treat. The development of treatments for social impairment is critical for the treatment of several psychiatric disorders. “Amyloban 3399,” a product extracted from the mushroom Hericium erinaceus, markedly improves social dysfunctions in patients with treatment‐resistant schizophrenia and depression. However, the molecular mechanism(s) through which amyloban ameliorates social impairment remains unclear. To clarify this mechanism, in this study, we aimed to establish a mouse model of social defeat stress (SDS) and investigate the effects of amyloban on social deficits. Amyloban administration ameliorated social deficits and the dopamine system activity in SDS mice. These findings suggest that there is a possibility that amyloban may improve social deficits by suppressing the hyperactivation of the dopaminergic system. Amyloban may be an effective treatment for social dysfunctions associated with various psychiatric disorders. [ABSTRACT FROM AUTHOR]

Mild-to-moderate ulcerative colitis (UC) management is centred on 5-aminosalicylic acid (5-ASA) derivatives. Whether supplementing 5-ASA with nutraceuticals can provide real advantages in UC-relevant outcomes is unclear. This retrospective multicentre study compared clinical remission, response rates, and faecal calprotectin levels in a two-arm design, including patients treated with 5-ASA alone and those with additional H. erinaceus-based multi-compound supplementation. In the 5-ASA alone group, clinical response rates were 41% at three months (T1) and 60.2% at six months (T2), while corresponding clinical remission rates were 16.9% and 36.1%. In the nutraceutical supplementation group, clinical response rates were 49.6% (T1) and 70.4% (T2), with clinical remission rates of 30.4% (T1) and 50.9% (T2). No significant differences in clinical response rates between the groups at T1 (p = 0.231) and T2 (p = 0.143) emerged. Clinical remission rates differed significantly at both time points (p = 0.029 and p = 0.042, respectively). Faecal calprotectin levels decreased significantly in both groups during the retrospective follow-up (p < 0.05), and this was more pronounced in nutraceutical supplementation patients at both T1 (p = 0.005) and T2 (p = 0.01). No adverse events were reported. This multi-component nutraceutical supplementation offers real-world potential in controlling disease activity in patients with mild-to-moderate UC.

Background: The neuroprotective effects of Dehydroepiandrosterone (DHEA) and Hericium erinaceus (H. erinaceus) mushroom extract against scopolamine-induced Alzheimer's disease-like symptoms in male Wistar rats were investigated. Methods: Sixty-four male Wistar rats were divided into eight groups (n = 8). Scopolamine (SCO) was intraperitoneally injected at a dose of 1 mg/kg/day for 10 days. The treatment groups orally received DHEA (250 mg/kg/day) and/or H. erinaceus (300 mg/kg/day) for 14 days. Afterward, the Morris water maze (MWM) and novel object recognition tests were implemented. Then, animals were anesthetized and the brain tissue samples were separated. Levels of lipid peroxidation (LPO), total antioxidant capacity (TAC), catalase activity (CAT), and brain-derived neurotrophic factor (BDNF) were determined. Also, histopathological studies were evaluated in the brain tissue samples. Results: Administration of SCO significantly decreased spatial and cognitive memory (p < 0.001). Not only did SCO injection significantly increase the levels of the LPO but also the SCO markedly reduced the levels of the TAC, CAT activity, and the BDNF in the brain tissue. On the other hand, a combination of the DHEA and H. erinaceus showed higher efficacy than the DHEA or H. erinaceus in attenuating behavioral anomalies and improving the antioxidant defense system and BDNF levels. Histological examination was well correlated with biochemical findings regarding SCO neurodegeneration and DHEA and/or H. erinaceus neuroprotection. Conclusion: Interestingly, ADHE and/or H. erinaceus may due to their potential neurotrophic properties be used as a new and beneficial concurrent therapy in the treatment of Alzheimer's disease-like symptoms caused by SCO.

An alkali-soluble β-glucan (AHEP-A-b, 20 kDa) purified from Hericium erinaceus fruiting bodies, was structurally characterized and examined for antioxidant activity. Methylation analysis and NMR spectroscopy show that the backbone of AHEP-A-b is composed of (1→6)-linked-D-β-glucopyran residues, branched at O-3 of glucopyranose (Glcp) residues with [→3)-β-D-Glcp-(1→] oligosaccharides or single unit of β-Glcp. Periodate oxidation analysis and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) indicate that the degree of polymerization (DP) of [→3)-β-D-Glcp-(1→] side chains is 2 to 8. Functionally, AHEP-A-b is a relatively strong antioxidant as demonstrated by using 2, 2′-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) free radical (ABTS·+), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals, and hydroxyl radicals scavenging assays. The present study lays the foundation for further studies into structure-activity relationships of polysaccharides from H. erinaceus. [ABSTRACT FROM AUTHOR]

For the first time, a study was conducted to determine the effectiveness of the use of Hericium erinaceus BP 16 polysaccharides mixed with AndroMed® to preserve the motility of bull spermatozoa after freezing and storage at -5 °C. H. erinaceus polysaccharides have been shown to increase the osmolarity of AndroMed® solution, which lowers its freezing point. It has been established that the motility of progressive spermatozoa after 7 days of storage at - 5°C is preserved to the greatest extent in the presence of H. erinaceus polysaccharides in the biological medium. At the same time, in the group with polysaccharides, there was a decrease in such indicators of mobility as the speed along the average trajectory, wobble, and beat frequency. The data obtained indicate the promise of using H. erinaceus polysaccharides as part of a cryoprotective solution to preserve the functional usefulness of gametes during their freezing.

Drinking coffee is a daily routine for many people. Supplement manufacturers have proposed adding powdered Cordyceps militaris, known for its ergogenic and immunostimulating properties, and Hericium erinaceus, known for its nerve growth factor (NGF)-stimulating properties, to coffee. The aim of this work was to compare the bioactive substances in three types of coffee: machine-brewed, instant, and traditionally brewed, prepared with the addition of H. erinaceus and C. militaris fruiting bodies. The analysis of bioactive substances was performed using AAS and RP-HPLC methods. Among the control samples of coffee, traditionally brewed coffee was the best source of bioelements. Considering the mushroom species tested, the best additional source of Mg, Zn, Cu, Na, K, and Ca was C. militaris. A slightly higher Fe content was determined for H. erinaceus. With the addition of C. militaris, the amounts of 4-feruloylquinic acid (18.6 mg/200 mL) and 3,5-di-caffeoylquinic acid (3.76 mg/200 mL) also increased. In conclusion, the C. militaris species has been proven to be a better source of bioactive substances as a coffee additive in the daily diet. The combination of brewed coffee and the tested mushrooms seems to be the most beneficial in terms of health-promoting effects. [ABSTRACT FROM AUTHOR]

Hericium erinaceus is a species of mushroom with high nutritional value that is used mainly as food in tropical countries. Phytochemical study of H. erinaceus led to the isolation of an undescribed compound, named as hericium VN (1), together with nine known compounds, 1-(2-formyl-1-pyrrolyl)butanoic acid (2), herierin III (3), 5′-(methylthio)adenosine (4), adenosine (5), nicotinic acid (6), (22E,24R)-5α,8α-epidioxyergosta-6,9(11),22-trien-3β-ol (7), 5α,8α-peroxycerevisterol (8), (22E,24R)-5α,8α-epidioxy-egosta-6,22-diene 3-O-β-D-glucopyranoside (9), and cerevisterol (10) based on extensive analyses of HR-ESI-MS, 1D and 2D NMR spectra. The absolute configuration of compound 1 was determined by experimental combined with calculated electronic circular dichroism spectra. Compound 7 exhibited cytotoxic effects against brain tumor cell line CCF-STTG1 with the IC50 value of 15.50 µM, compared to that of the positive control compound, doxorubicin, which showed IC50 value of 15.84 µM.

Hericium erinaceus has long been favored for its remarkable nutritional and health-promoting benefits, and erinacine A is the key component responsible for the neuroprotective properties of H. erinaceus. Establishing an efficient method for separating erinacine A from H. erinaceus and screening the erinacine A-enriched strains is crucial to maximizing its benefits. Herein, we first reported that high-speed counter current chromatography (HSCCC) is an effective method for separating high-purity erinacine A. Using a two-phase solvent system composed of n-hexane/ethyl acetate/methanol/water (4.5:5:4.5:5, v/v/v/v), erinacine A with a purity of over 95% was separated. Then, we evaluated the content and yield of erinacine A in the liquid-fermented mycelia of Hericium germplasms. Both the content and yield of erinacine A varied greatly among the surveyed strains. The significant effect of the strain on the erinacine A content and yield was revealed by an analysis of variance. The highest erinacine A content and yield were observed in the mycelia of a wild strain HeG, reaching 42.16 mg/g and 358.78 mg/L, which is superior to the current highest outcomes achieved using submerged cultivation. The isolation method established and the strains screened in this study can be beneficial for the scaling up of erinacine A extraction and nutraceutical development to industrial levels.

A high protein food that is easy to swallow for people with dysphagia was prepared by blending milk with Hericium erinaceus (HE) powder, soy protein isolate (SPI) or whey protein (WP) (which was added to obtain a final protein content more than 10% of the total mass), and one of three thickeners including xanthan gum (XG), kappa carrageenan (KC) and carboxymethylcellulose (CMC), and its rheology, viscoelastic properties and in vitro digestion characteristics were determined. The results showed that all samples exhibited a weak gel behavior. According to the steady-state rheological test, the values of high resistance to deformation (high G* value) and good elasticity (low tan δ value) were ranked as follows: HE-SPI-CMC > HE-SPI-XG > HE-WP-XG > HE-WP-KC, and higher G* values were more favorable for people with dysphagia and the elderly. In the in vitro simulated digestion test, the viscosity (η) and consistency coefficient (K) values were in the following order: HE-WP-KC > HE-WP-XG > HE-SPI-XG. The soluble protein contents were ranked as follows: HE-WP-CMC > HE-WP-KC > HE-SPI-KC. The contents of free amino acids after digestion were in the following order: HE-WP-CMC > HE-WP-KC > HE-SPI-KC > HE-WP-XG. Therefore, HE-WP-KC was more suitable for consumption by the elderly. This study has explained how protein-hydrocolloid interactions and food matrix determine the rheological properties and digestibility properties of the samples, which may provide theoretical support for meeting the dietary needs of people with dysphagia.

AbstractHericium erinaceus (Bull.:Fr.) Pers., 1797, is an edible and medicinal fungus found in China. In this study, specimens of H. erinaceus HE0021 were collected from southeastern China (Yunhe County, Lishui City, Zhejiang Province, 28°7′12″N, 119°34′12″E). The whole mitochondrial genome of H. erinaceus HE0021 was sequenced using next-generation sequencing (NGS) technology, which comprised 15 protein-coding genes (PCGs), 27 transfer RNAs (tRNAs), two ribosomal RNAs, with a total length of 83,518 base pairs (bp). The results of the phylogenetic analysis show that H. erinaceus and H. coralloides were clustered in the same clade. The complete mitogenome sequence provides essential data for the subsequent investigation of Hericium and Russulales.

Mushrooms are one of the indispensable elements of human diets. Edible mushrooms stand out with their aroma and nutritional properties. In this study, some biological activities of the wild edible mushroom Hericium erinaceus were determined. In this context, firstly, the most suitable extraction conditions of the fungus in terms of biological activity were determined. First, 64 different experiments were performed with the Soxhlet device under 40–70 °C extraction temperature, 3–9 h extraction time, and 0.5–2 mg/mL extraction conditions. As a result, a total antioxidant status (TAS) analysis was performed, and the extraction conditions were optimized so that the objective function was the maximum TAS value. The data obtained from the experimental study were modeled with artificial neural networks (ANNs), one of the artificial intelligence methods, and optimized with a genetic algorithm (GA). All subsequent tests were performed using the extract obtained under optimum extraction conditions. The antioxidant capacity of the mushroom was assessed using Rel assay kits and the DPPH and FRAP techniques. The agar dilution method was used to measure the antimicrobial activity. The anti-Alzheimer activity was assessed based on the activities of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The antiproliferative activity was assessed against the A549 cancer cell line. The total phenolic content was measured using the Folin–Ciocalteu reagent. The measurement of total flavonoids was conducted using the aluminum chloride test. LC-MS/MS equipment was used to screen for the presence of standard chemicals. The optimum extraction conditions were found to be a 60.667 °C temperature, 7.833 h, and 1.98 mg/mL. It was determined that the mushroom has high antioxidant potential. It was determined that the substance was successful at combating common bacterial and fungal strains when used at dosages ranging from 25 to 200 µg/mL. The high antiproliferative effect of the substance was attributed to its heightened concentration. The anti-AChE value was found to be 13.85 μg/mL, while the anti-BChE value was confirmed to be 28.00 μg/mL. The phenolic analysis of the mushroom revealed the presence of 13 chemicals. This investigation found that H. erinaceus exhibits robust biological activity when extracted under appropriate circumstances. [ABSTRACT FROM AUTHOR]

Lion's Mane (Hericium erinaceus) has historically been used as traditional medicine in Asia and Europe for its potential benefits in fighting infection and cancer. It has gained interest in the neurodegenerative disease field because of its mechanisms of action; these include anti-inflammation, neuroprotection, and promoting neurite growth demonstrated in various cell and animal models. A very small, double-blind, placebo-controlled trial in patients with mild cognitive impairment showed a temporary improvement in cognitive function; this finding has yet to be replicated. However, there have been no studies in ALS cell or animal models or in humans with ALS. Lion's Mane appears safe and inexpensive when consumed in powder or capsule, but one anaphylactic case was reported after a patient consumed fresh Lion's Mane mushroom. Currently, we do not have enough information to support the use of Lion's Mane for treating ALS. We support further research in ALS disease models and clinical trials to study its efficacy.

To investigate the effects of edible mushrooms on colonic luminal variables, including fecal mucins, organic acids, microbial composition, immunoglobulin A (IgA), alkaline phosphatase (ALP) and cecal organic acids, male Sprague-Dawley rats were fed a 30% lard diet containing one of 12 species of edible mushrooms for 2 weeks. We found that the dietary intake of shiitake (Lentinula edodes), enokitake (Flammulina velutipes), white button (Agaricus bisporus) and yamabushitake (Hericium erinaceus) mushrooms elevated fecal ALP activity as well as increased fecal IgA, mucins, fecal Bacteroides ratio, and cecal total organic acids. In contrast, the intake of dietary eringi (Pleurotus eryngii), maitake (Grifola frondosa), tamogitake (Pleurotus cornucopiae), wood ear (Auricularia auricula-judae) and bunashimeji (Hypsizygus marmoreus) mushrooms had minimal effects on the colonic environment factors. We speculated that edible mushrooms could be grouped according to their effects on the colonic luminal environment. [ABSTRACT FROM AUTHOR]

Hot air-assisted radio frequency (HARF) is considered a rapid heating process. In order to improve the circular economy of agricultural byproducts, this study used different proportions of HARF stabilized rice bran (R) from milling rice, HARF dried ginseng residue (G) from ultrasonic extraction, and peanut residue (P) from HARF roasting and oil extraction as the Hericium erinaceus solid-state fermented media. Then, the whitening effects of water extracts from media and fermented products were analyzed. First, the surface temperature of 1 kg rice bran exceeded 90 °C after 3 min of 5 kW HARF heating, effectively deactivating lipase. The combinations of 1 kg of rice bran with 0.5, 1, 1.5, and 2 kg of ginseng residue (85% moisture content) were dried using 5 kW HARF. Each of the drying rates was about 27 g/min, and the drying periods were 14, 30, 46, and 62 min, respectively, which were used to reduce the moisture content below 10%. Compared to traditional air drying for ginseng residue, HARF drying may save up to 96% of time and 91% of energy consumption. Then, the ratio of dried R, G, and P was 4:1:1, mixed with 45% moisture as solid-state media for Hericium erinaceus and 5 weeks of cultivation at 25 °C. In comparison to the control group, the water extracts at 100 µg/mL from media R4G1, R4G1P1, and fermented HER4G1P1 products exhibited tyrosinase inhibition of 29.7%, 52.4%, and 50.7%, respectively. These extracts also reduced the relative melanin area of 78 hpf zebrafish embryos by 21.57%, 40.20%, and 58.03%, respectively. Therefore, HARF can quickly dry agricultural byproducts as media for Hericium erinaceus solid-state fermentation while also providing a significant whitening effect for cosmetic applications.

Spinocerebellar ataxia type 3 (SCA3) is an autosomal dominant neurodegenerative disorder that gives rise to motor incoordination and progressive functional disabilities. Although pharmacological interventions have revealed promising prospects in the management of SCA3, adverse effects may become unbearable. The use of herbal remedies in traditional Chinese medicine (TCM) may serve as potential alternative medicines to delay the progression of the disease. This systematic review is intended to identify, appraise, and summarize the findings of studies pertaining to the therapeutic roles of herbal remedies in TCM targeting oxidative stress in the management of SCA3. A literature search for relevant articles published from 1 January 2013 to 30 June 2023 in three databases, namely PubMed, Web of Science, and Scopus, was carried out according to the procedures of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A total of ten preclinical studies met the inclusion criteria of the systematic review. We recognized the therapeutic potential of Brassica napus, Codonopsis pilosula, Curcuma sp., Gardenia jasminoides, Gastrodia elata, Ginkgo biloba, Glycyrrhiza inflata, Hericium erinaceus, Hyptis sp., Paeonia lactiflora, Panax ginseng, Poria cocos, Pueraria lobata, Rehmannia glutinosa, and Scrophularia ningpoensis. We identified the types of preclinical models expressing polyglutamine (polyQ) expanded mutant protein (mATXN3), inducers of oxidative stress that mimic the SCA3 pathogenesis, and effective doses of the herbal remedies. The modes of action contributing to the attenuation of oxidative stress are activation of antioxidant pathways, ubiquitin–proteasome system and autophagy, regulation of apoptosis, proinflammatory signaling pathway and chaperones, regulation of mitochondrial function and biogenesis, and restoration of neurotransmission and synaptic plasticity. In conclusion, herbal remedies in TCM may possibly delay the progression of SCA3, therefore providing justification for clinical trials. [ABSTRACT FROM AUTHOR]

Hericium erinaceus, a consumable mushroom, has shown a potential to enhance the production of neuroprotective bioactive metabolites. Traumatic brain injury (TBI) often leads to cognitive, physical, and psychosocial impairments, resulting in neuroinflammation and the loss of cortical neurons. In this research, the effects of H. erinaceus mycelium, its derivative erinacine C, along with the underlying mechanisms, were examined in terms of oxidative stress modulation and neurological improvement in a rat model of mild traumatic brain injury (mTBI). Male Sprague-Dawley rats were administered diets containing H. erinaceus mycelium and erinacine C following experimental brain injury; these supplements were continued throughout the recovery phase. The binding activity of NF-E2-related factor 2 (Nrf2) near antioxidant genes in mixed glial cells was measured by chromatin immunoprecipitation-quantitative polymerase chain reaction (ChIP-qPCR). The motor beam walking test revealed that dietary supplementation of H. erinaceus mycelium resulted in modest improvements in spatial memory while inhibiting neuron cell death and microglial activation according to brain histological examination. These findings were further corroborated by the upregulation of several antioxidant enzymes (catalase, glutathione reductase, thioredoxin reductase, and superoxide dismutase) and phospho-CAMP-response element-binding (p-CREB) levels in the mTBI model treated with H. erinaceus mycelium. Erinacine C treatment led to significantly reduced brain inflammation and normalization of mTBI-induced deficits through the modulation of the Nrf2 activation pathway and upregulated expression of numerous Nrf2-binding antioxidant genes such as catalase, thioredoxin reductase, superoxide dismutase, and brain-derived neurotrophic factor. This study demonstrates the potential of H. erinaceus mycelium and erinacine C in facilitating recovery following mTBI, including the prevention of neuronal injury and inactivation of microglia through the Nrf2-mediated antioxidant pathway in vivo.

A total of twelve previously unreported isoindolin-1-one compounds, erinacenones A–L (1–12), were isolated from liquid cultures of the medicinal fungus Hericium erinaceus. Their structures were elucidated based on spectroscopic data analysis. The absolute configuration of 12 was determined by comparing its optical rotations with values reported in the literature. The most distinctive feature of these compounds is that their nitrogen atoms are connected to different parts of the special structure moieties. Among them, compounds 3 and 4, as well as 10 and 11, are two pairs of isomers differing only by a small change in the position of one double bond. Compounds 4 and 5 were found to show cytotoxic activities, with IC50 values of 24.7 and 18.4 μM, respectively, against MCF-7 cell lines.

Corn husk, a by-product of corn starch production and processing, contains high-quality dietary fiber (DF). Our study compares and analyzes the impact of Hericium erinaceus solid-state fermentation (SSF) on the structure and physicochemical characteristics of soluble dietary fiber (SDF) of corn husks. The study also investigates the kinetics of SSF of H. erinaceus in this process. The scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR) results revealed significant structural changes in corn husk SDF before and after fermentation, with a significant elevation in the functional group numbers. The data indicate that the fermented corn husk SDF’s water-holding, swelling, and oil-holding capacities increased to 1.57, 1.95, and 1.80 times those of the pre-fermentation SDF, respectively. Additionally, the results suggest that changes in extracellular enzyme activity and nutrient composition during SSF of H. erinaceus are closely associated with the mycelium growth stage, with a mutual promotion or inhibition relationship between the two. Our study offers a foundation for corn husk SDF fermentation and is relevant to the bioconversion of maize processing by-products.

One new compound with an isoindolinone skeleton, along with erinacines A, C, and S, was isolated from the mycelia of Hericium erinaceus, an edible fungus with a long history of use in traditional Chinese medicine. Based on analysis of MS and NMR spectral data, the structure of the compound was identified as (2E,6E)-8-(2-(1-carboxy-3-methylbutyl)-4,6-dihydroxy-1-oxoisoindolin-5-yl)-2,6-dimethylocta-2,6-dienoic acid. In light of this discovery, we have given this compound the name erinacerin W. Using a co-culture in vitro LPS-activated BV2 microglia-induced SH-SY5Y neuroinflammation model, the results showed that erinacerin W demonstrated protection against the LPS-activated BV-2 cell-induced overexpression of IL-6, IL-1β, and TNF-α on SH-SY5Y cells. This finding may provide potential therapeutic approaches for central nervous disorders. [ABSTRACT FROM AUTHOR]

In this review we focused on the putative therapeutic effect of Hericium erinaceus extract in the treatment of pathologic conditions of the lower urinary tract in which intestinal inflammation may play a role. To this aim we reviewed the available evidence on pelvic cross-organ sensitization as a possible mechanism through which intestinal inflammation and dysbiosis may affect the lower urinary tract. Also, we reviewed the clinical and experimental evidence supporting the role of Hericium erinaceus extract as an anti-inflammatory agent highlighting the role of a number of putative mediators and mechanisms which might make this nutraceutical suitable for the management of 'difficult to treat' lower urinary tract disorders.

Simple Summary: The gut microbiome is a complex and unendingly changing community of bacteria that lives inside animals, including humans. Emerging evidence has proved that gut microbiome composition is associated with several human health outcomes, which include cognitive performance. However, few epidemiological studies exist, and research in this field is still ongoing and developing. The current article suggests that oral consumption of an edible medicinal mushroom named H. erinaceus promotes the growth of beneficial gut bacteria, parallelly reducing pathogen bacteria, therefore revealing its prebiotic effect. Additionally, this oral supplementation had a positive impact on cognitive function, also leading to a decrease in inflammation in the hippocampus, a brain area crucially involved in memory formation and consolidation. Overall, these findings support the notion that changing the gut microbiome composition through nutrition modulation could trigger longevity-promoting effects, protecting from age-related cognitive decline. Ageing is a biological phenomenon that determines the impairment of cognitive performances, in particular, affecting memory. Inflammation and cellular senescence are known to be involved in the pathogenesis of cognitive decline. The gut microbiota–brain axis could exert a critical role in influencing brain homeostasis during ageing, modulating neuroinflammation, and possibly leading to inflammaging. Due to their anti-ageing properties, medicinal mushrooms can be utilised as a resource for developing pharmaceuticals and functional foods. Specifically, Hericium erinaceus (He), thanks to its bioactive metabolites, exerts numerous healthy beneficial effects, such as reinforcing the immune system, counteracting ageing, and improving cognitive performance. Our previous works demonstrated the capabilities of two months of He1 standardised extract oral supplementation in preventing cognitive decline in elderly frail mice. Herein, we showed that this treatment did not change the overall gut microbiome composition but significantly modified the relative abundance of genera specifically involved in cognition and inflammation. Parallelly, a significant decrease in crucial markers of inflammation and cellular senescence, i.e., CD45, GFAP, IL6, p62, and γH2AX, was demonstrated in the dentate gyrus and Cornus Ammonis hippocampal areas through immunohistochemical experiments. In summary, we suggested beneficial and anti-inflammatory properties of He1 in mouse hippocampus through the gut microbiome–brain axis modulation. [ABSTRACT FROM AUTHOR]

The aim of this study was to assess the effects of guayusa extract and Nordic Lion's Mane (LM) on cognition. Using a randomized, double-blind, placebo-controlled, crossover design, we examined the effects of a single dose of 650 mg guayusa extract (AMT: AmaTea® Max) vs. 1 g Nordic-grown Lion's Mane (LM) vs. placebo (PL). Participants attended three testing visits consisting of neuropsychological tests (Go/No-go, N-Back, and Serial 7 s tasks) assessing performance, subjective assessments of cognitive perception, and vital signs. Each assessment was measured at baseline (pre-ingestion) and 1 and 2 h post ingestion. AMT significantly (p ≤ 0.05) improved the number of attempts during Serial 7s, total score, number of correct responses, total number of responses, and reaction time during N-Back and improved Go stimulus reaction time, but it reduced the percentage of correct responses in the No-go stimulus response during Go/No-go. LM significantly (p ≤ 0.05) improved the number of attempts during Serial 7s and reaction time during N-Back and improved Go stimulus reaction time in Go/No-go. AMT improved mental clarity, focus, concentration, mood, and productivity at 1 and 2 h (p < 0.05); the ability to tolerate stress at 1 h; and had greater ratings than LM and PL for mental clarity, focus, concentration, and productivity. PL improved focus and concentration at 1 h from baseline (p ≤ 0.05). AMT and LM improved subjective ratings of "happiness compared to peers" and "getting the most out of everything" (p < 0.05); however, this occurred earlier in LM (i.e., 1 h post ingestion). AMT uniquely elevated blood pressure from baseline. AMT significantly improved cognitive performance and self-perceived cognitive indices of affect over a 2 h period and perceptions of happiness 2 h post ingestion. In comparison, LM helped improve working memory, complex attention, and reaction time 2 h post ingestion and perceptions of happiness over a 2 h period. [ABSTRACT FROM AUTHOR]

Mushrooms have attracted interest since ancient times due to their nutritional composition and medicinal properties. In recent years, the antioxidant compounds of mushroom extracts have become an source of alternative synthetic antioxidant substances in pharmaceutical and food industries. In this context, researchers have become increasingly interested in edible and medicinal mushrooms. The aim of this study was to determine the nutritional composition, antioxidant potential, phenolic and flavonoid content of commercially purchased Hericium erinaceus mushroom and to evaluate its anticancer effect against A549 (lung adenocarcinoma) and HT-29 (human colon adenocarcinoma) cells. In this context, the nutrient composition was analyzed according to the Association of Official Analytical Chemists (AOAC) procedure. Hericium erinaceus showed a high nutritional value with protein, carbohydrate, dietary fiber and glucan content. The total phenolic and total flavonoid contents of water, ethanol and methanol extracts of this mushroom were determined and it was found that the methanol extract had the highest phenolic (27.12±1.05 mg GAE/g extract) and flavonoid (13.48±1.13 mg QE/g extract) contents among the three extract types. In addition, the antioxidant capacity of the extracts was compared by different methods (DPpH, ABTS, FRAP and CUPRAC). Methanol extract showed the highest DpPH (38.88±1.59 μM TE/g extract), FRAP (21.44±0.79 μM TE/g extract) and CUPRAC (30.05±1.80 μM TE/g extract) activities among the other extracts, while ABTS (24.44±1.07 μM TE/g extract) activity was the highest for ethanol extract. Finally, when the anticancer effects of these extracts against A549 and HT-29 cells were evaluated, it was observed that water, ethanol and methanol extracts inhibited A549 cells by 49.08%, 52.08% and 57.91% and HT-29 cells by 52.82%, 63.71% and 71.07%, respectively, at the end of 24 hours.

Population aging has led to an increased interest in various dietary supplements in order to preserve cognitive function. The aim of our study was to examine the effects of Hericium erinaceus supplementation (HE) on cognitive function and serum levels of Brain-Derived Neurotrophic Factor (BDNF) and Neuropeptide Y (NPY). An 8-week double-blind comparative study involved 33 subjects, randomly assigned to a HE group and a placebo (P) group. Anthropometric measurements and analyses of selected biochemical parameters were performed before and after the intervention. Simultaneously, faecal samples were collected to determine gut microbiota and chitinase 3-like-1 (CHI3L1) levels. Cognitive function was assessed using two non-verbal speed tests. In the HE group, a significant improvement in cognitive ability was observed when the corresponding cognitive scores at baseline, CHI3L1 level, age, and gender were considered. Moreover, in the HE group there was a significant increase in gut microbiota diversity that was positively correlated to NPY levels. The mechanism that could help to explain the results on the relationship between the active ingredients of the H. erinaceus and the cognitive parameters could point to the CHI3L1 activity that may enhance bioavailability of the bioactive ingredients. Supplementing the diet with HE was recognised as a safe and well-tolerated intervention with a neurocognitive benefit.

Mild-to-moderate ulcerative colitis (UC) management is centred on 5-aminosalicylic acid (5-ASA) derivatives. Whether supplementing 5-ASA with nutraceuticals can provide real advantages in UC-relevant outcomes is unclear. This retrospective multicentre study compared clinical remission, response rates, and faecal calprotectin levels in a two-arm design, including patients treated with 5-ASA alone and those with additional H. erinaceus-based multi-compound supplementation. In the 5-ASA alone group, clinical response rates were 41% at three months (T1) and 60.2% at six months (T2), while corresponding clinical remission rates were 16.9% and 36.1%. In the nutraceutical supplementation group, clinical response rates were 49.6% (T1) and 70.4% (T2), with clinical remission rates of 30.4% (T1) and 50.9% (T2). No significant differences in clinical response rates between the groups at T1 (p = 0.231) and T2 (p = 0.143) emerged. Clinical remission rates differed significantly at both time points (p = 0.029 and p = 0.042, respectively). Faecal calprotectin levels decreased significantly in both groups during the retrospective follow-up (p < 0.05), and this was more pronounced in nutraceutical supplementation patients at both T1 (p = 0.005) and T2 (p = 0.01). No adverse events were reported. This multi-component nutraceutical supplementation offers real-world potential in controlling disease activity in patients with mild-to-moderate UC.

An alkali-soluble β-glucan (AHEP-A-b, 20 kDa) purified from Hericium erinaceus fruiting bodies, was structurally characterized and examined for antioxidant activity. Methylation analysis and NMR spectroscopy show that the backbone of AHEP-A-b is composed of (1→6)-linked-D-β-glucopyran residues, branched at O-3 of glucopyranose (Glcp) residues with [→3)-β-D-Glcp-(1→] oligosaccharides or single unit of β-Glcp. Periodate oxidation analysis and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) indicate that the degree of polymerization (DP) of [→3)-β-D-Glcp-(1→] side chains is 2 to 8. Functionally, AHEP-A-b is a relatively strong antioxidant as demonstrated by using 2, 2′-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) free radical (ABTS·+), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals, and hydroxyl radicals scavenging assays. The present study lays the foundation for further studies into structure-activity relationships of polysaccharides from H. erinaceus.

Drinking coffee is a daily routine for many people. Supplement manufacturers have proposed adding powdered Cordyceps militaris, known for its ergogenic and immunostimulating properties, and Hericium erinaceus, known for its nerve growth factor (NGF)-stimulating properties, to coffee. The aim of this work was to compare the bioactive substances in three types of coffee: machine-brewed, instant, and traditionally brewed, prepared with the addition of H. erinaceus and C. militaris fruiting bodies. The analysis of bioactive substances was performed using AAS and RP-HPLC methods. Among the control samples of coffee, traditionally brewed coffee was the best source of bioelements. Considering the mushroom species tested, the best additional source of Mg, Zn, Cu, Na, K, and Ca was C. militaris. A slightly higher Fe content was determined for H. erinaceus. With the addition of C. militaris, the amounts of 4-feruloylquinic acid (18.6 mg/200 mL) and 3,5-di-caffeoylquinic acid (3.76 mg/200 mL) also increased. In conclusion, the C. militaris species has been proven to be a better source of bioactive substances as a coffee additive in the daily diet. The combination of brewed coffee and the tested mushrooms seems to be the most beneficial in terms of health-promoting effects.

Recently, owing to the good calcium bioavailability, peptide–calcium chelates made of various foods have been emerging. Hericium erinaceus, an edible fungus, is rich in proteins with a high proportion of calcium-binding amino acids. Thus, mushrooms serve as a good source to prepare peptide–calcium chelates. Herein, the conditions for hydrolyzing Hericium erinaceus peptides (HP) with a good calcium-binding rate (CBR) were investigated, followed by the optimization of HP–calcium chelate (HP-Ca) preparation. Furthermore, the structure of the new chelates was characterized along with the evaluation of gastrointestinal stability and calcium absorption. Papain and a hydrolysis time of 2 h were selected for preparing Hericium erinaceus peptides, and the conditions (pH 8.5, temperature 55°C, time 40 min, and mass ratio of peptide/CaCl2 4:1) were optimal to prepare HP-Ca. Under this condition, the chelates contained 6.79 ± 0.13% of calcium. The morphology and energy disperse spectroscopy (EDS) analysis showed that HP-Ca was loose and porous, with an obvious calcium element signal. The ultraviolet–visible (UV) absorption and Fourier transform infrared spectroscopy (FT-IR) analysis indicated that calcium possibly chelates to HP via interaction with free -COO- from acidic amino acids and C = O from amide. HP-Ca displayed good stability against stimulated gastrointestinal digestion. Moreover, HP-Ca significantly improved the calcium absorption by Caco-2 epithelial cells. Thus, HP-Ca is a promising Ca supplement with high calcium bioavailability.

Background: Given the bioactive properties and limited work to date, Hericium erinaceus (Lion's mane) shows promise in improving cognitive function and mood. However, much of the human research has concentrated on chronic supplementation in cognitively compromised cohorts. Objective: The current pilot study investigated the acute and chronic (28-day) cognitive and mood-enhancing effects of Hericium erinaceus in a healthy, young adult cohort. Design: This randomized, double-blind, placebo-controlled, parallel-groups design investigated the acute (60 min post dose) and chronic (28-day intervention) effects of 1.8 g Hericium erinaceus in 41 healthy adults aged 18–45 years. Results: Analysis revealed that following a single dose of Hericium erinaceus, participants performed quicker on the Stroop task (p = 0.005) at 60 min post dose. A trend towards reduced subjective stress was observed following 28-day supplementation (p = 0.051). Conclusions: The findings tentatively suggest that Hericium erinaceus may improve speed of performance and reduce subjective stress in healthy, young adults. However, null and limited negative findings were also observed. Given the small sample size, these findings should be interpreted with caution. Further investigation in larger sample sizes is crucial, however the findings of this trial offer a promising avenue of interest. [ABSTRACT FROM AUTHOR]

Hericium erinaceus is a valuable mushroom known for its strong bioactive properties. It shows promising potential as an excellent neuroprotective agent, capable of stimulating nerve growth factor release, regulating inflammatory processes, reducing oxidative stress, and safeguarding nerve cells from apoptosis. The active compounds in the mushroom, such as erinacines and hericenones, have been the subject of research, providing evidence of their neuroprotective effects. Further research and standardization processes for dietary supplements focused on H. erinaceus are essential to ensuring effectiveness and safety in protecting the nervous system. Advancements in isolation and characterization techniques, along with improved access to pure analytical standards, will play a critical role in achieving standardized, high-quality dietary supplements based on H. erinaceus. The aim of this study is to analyze the protective and nourishing effects of H. erinaceus on the nervous system and present the most up-to-date research findings related to this topic.
