Lilii Bulbus is a folk medicine for both culinary and medicinal purpose. In traditional medicine theory, Lilii Bulbus is usually used as an complementary therapy for nourishing the heart and lung, clearing heat in the treatment of mental instability and depression. In this study, NLPS-1a (Mw = 2610 Da, DP = 16), a water-soluble non-starch Lilii Bulbus polysaccharides, was isolated and purified. Structural analysis showed that NLPS-1a mainly contained Man and Glc with a molar ratio of 11.137 and 9.427. The glycosidic linkages of NLPS-1a were 1,3-Manp (59.93%), 1,2-Glcp (37.93%), T-Glcp (1.21%) and T-Manp (0.93%), indicating the highly-linear structures. In addition, NLPS-1a could significantly repair the injury of PC12 cells induced by corticosterone (CORT), reduce Lactate dehydrogenase (LDH) leakage and decrease the cell apoptosis in a dose-dependent manner. Above all, the results indicated that NLPS-1a had protective effects against CORT-induced neurotoxicity in PC12 cells, and might be a natural antidepressant, which enriched the study of the metabolic mechanism between herbal polysaccharides and antidepressant.

Lilii Bulbus (Lilium lancifolium Thunberg) has a proneurogenic effect on the hippocampus. However, its effects on epilepsy and associated pathological features remain unknown. In this study, we investigated the antiseizure effects of a water extract of Lilii Bulbus (WELB) in mouse model of pentylenetetrazol (PTZ)-induced seizure. Mice were injected with PTZ once every 48 h until full kindling was achieved. WELB (100 and 500 mg/kg) was orally administered once daily before PTZ administration and during the kindling process. We found that WELB treatment protected against PTZ-induced low seizure thresholds and high seizure severity. Further, WELB-treated mice showed attenuated PTZ kindling-induced anxiety and memory impairment. Immunostaining and immunoblots showed that hyperactivation and ectopic migration of dentate granule cells (DGCs) were significantly reduced by WELB treatment in PTZ kindling-induced seizure mice. Staining for mossy fiber sprouting (MFS) using Timm staining and ZnT3 showed that WELB treatment significantly decreased PTZ kindling-induced MFS. Furthermore, the increased or decreased expression of proteins related to ectopic DGCs (Reelin and Dab-1), MFS (Netrin-1, Sema3A, and Sema3F), and their downstream effectors (ERK, AKT, and CREB) in the hippocampus of PTZ kindling mice was significantly restored by WELB treatment. Overall, our findings suggest that WELB is a potential antiseizure drug that acts by reducing ectopic DGCs and MFS and modulating epileptogenesis-related signaling in the hippocampus.

Edible and medicinal plants (EMPs) are widely used but are easily infected by harmful fungi which produce mycotoxins. Herein, 127 samples from 11 provinces were collected to investigate 15 mycotoxins based on geographic, demographic, processing, and risk characteristics. A total of 13 mycotoxins were detected, and aflatoxin B1 (0.56~97.00 μg/kg), deoxynivalenol (9.41~1570.35 μg/kg), fumonisin B1 (8.25~1875.77 μg/kg), fumonisin B2 (2.74~543.01 μg/kg), ochratoxin A (0.62~19.30 μg/kg), and zearalenone (1.64~2376.58 μg/kg) occurred more frequently. Mycotoxin levels and species were significantly different by region, types of EMPs, and method of processing. The margin of exposure (MOE) values was well below the safe MOE (10,000). AFB1 exposure from Coix seed and malt consumption in China was of high health concern. The hazard Index (HI) method showed the range of 113.15~130.73% for malt, indicating a public health concern. In conclusion, EMPs should be concerned because of the cumulative effects of co-occurred mycotoxins, and safety management strategies should be developed in follow-up studies. [ABSTRACT FROM AUTHOR]

Lilii Bulbus, the bulb of tiger lily, has anti-oxidant and anti-tumorigenic properties. However, the effects of Lilii Bulbus on learning, memory, and hippocampal neurogenesis remain unknown. This study investigated whether water extract of Lilii Bulbus (WELB) affects memory ability and hippocampal neurogenesis. Behavioral analyses (Morris water maze and passive avoidance test), immunohistochemistry, cell proliferation assay, and immunoblot analysis were performed. WELB (50 and 100 mg/kg; for 14 days) enhanced memory retention and spatial memory in normal mice as well as in scopolamine-treated mice with memory deficits. Furthermore, the administration of WELB significantly increased the number of proliferating cells and surviving newborn cells in the dentate gyrus of the hippocampus in normal mice. We found that WELB has a pro-neurogenic effect by increasing the activation of brain-derived neurotrophic factor (BDNF)/cAMP response element-binding protein (CREB) and mitogen-activated protein kinase kinase/extracellular signal-regulated kinase (MEK/ERK) in the hippocampus. Moreover, we confirmed that WELB (100 and 200 μg/ml) significantly increased NE-4 C and primary embryonic NSCs proliferation. Inhibition/knockdown of MEK/ERK blocked WELB-induced MEK/ERK phosphorylation and NSCs proliferation. Hence, MEK/ERK activation was required in WELB-induced NSCs proliferation. Our study demonstrates the first evidence for WELB promoting hippocampal neurogenesis and memory; pro-neurogenic activity may enhance brain plasticity, with implications for treating neurodegenerative diseases.

Lilii Bulbus, an edible Chinese herbal medicine, has a long history in medicine. However, research on effectively boiling Lilii Bulbus is rare. To make the more nutritious Lilii Bulbus soup, the optimized boiling process, using an alternate heating mode by decoction pot carrying a mixture of water and Chinese liquor at the ration of 9:1, was established in this study. Compared to the soup prepared by the daily process, the polysaccharide amount improved by 54%, and the total heavy metals decreased by 33.5% using the optimized boiling process. In addition, the total saponins at 34.3 μg/g were determined in the soup prepared by the optimized process. Meanwhile, the colchicine content in the boiled Lilii Bulbus soup was undetectable using the optimized process. This research performs an optimized boiling process for making Lilii Bulbus soup, and provides a reference for generating high commercial value from Lilii Bulbus soup in the future.

Objectives: Lilii Bulbus (LB), a lung-moistening herbal medicine, has been used to treat the symptoms of pulmonary fibrosis, including dry cough and dyspnea. In this study, we investigated whether LB water extract (LIB) has antifibrotic effects in a mouse model of bleomycin-induced pulmonary fibrosis. Materials and Methods: The effects of LIB and its mechanisms of action were investigated in a mouse model of bleomycin-induced (2 mg/kg, intratracheal) pulmonary fibrosis. LIB (30, 100, and 300 mg/kg) was administered orally twice daily for 10 days after induction. Changes in body weight, lung histology, inflammatory cells in bronchoalveolar lavage fluid (BALF), and the levels of transforming growth factor (TGF)-β, α-smooth muscle actin (α-SMA), and proinflammatory cytokines were evaluated. Results: LIB treatment decreased histological fibrotic change according to Ashcroft score, inflammatory cells, including total cells, macrophages, inflammatory cytokines (tumor necrosis factor-α and interleukin-6) in BALF, and TGF-β and α-SMA production in lung tissue. Conclusion: LIB exerted antifibrotic effects in a mouse model of bleomycin-induced pulmonary fibrosis by inhibiting inflammatory reactions and fibrotic mediators including TGF-β and α-SMA.

Exposure to PM2.5 (particulate matter with an aerodynamic diameter ≤ 2.5 μm) has been associated with increased cardiopulmonary outcomes, mediated by a hypothesized biological mechanism of systemic inflammation and oxidation. This randomized, double‐blinded and placebo‐controlled trial among 120 healthy adults in Wuhan, China, was conducted to evaluate whether the supplementation of herbal product composed of Ginseng, Lilii Bulbus and Poria (GLP) which have been shown to have anti‐inflammatory and anti‐oxidant activity offers protective effects on PM2.5‐induced damage to cardiopulmonary health. Participants received four rounds of health examinations and two rounds of blood sample collection from November 2018 to January 2019. Compared to the placebo group, the GLP group showed significant increased antioxidant biomarkers such as superoxide dismutase (SOD) and paraoxonase1 (PON1). What is more, interleukin‐6 (IL‐6), an inflammatory biomarker, was significantly decreased in the GLP group. In addition, nitric oxide and club cell secretory protein (CC16) were increased but heart rate was decreased in the GLP group. As for pulmonary function indicators, significantly increased fractional exhaled nitric oxide (FeNO) was observed in the GLP group. Taken together, we concluded that GLP supplementation is associated with decreased inflammatory biomarker and increased antioxidant biomarkers suggesting cardiopulmonary benefits against PM2.5 exposure among young adults in China.

Lilium brownii var. viridulum Baker is an economically important plant, and its bulbs are popular among consumers for their high nutritional value. Due to the influence of environment, the chemical composition of lily from different origin is different, which leads to the different medicinal and nutritional values. Thus, it is very significant and necessary to discriminate the origins of lily. In this study, lipid classes and molecular species of lily samples from eight origins were identified and quantified by UHPLC-QE-Orbitrap/MS/MS and combined with chemometrics for modeling and analysis. The results showed that a total of 16 lipid classes and 88 lipid molecules were identified and quantified. The partial least squares discriminant analysis (PLS-DA) showed that there were significant differences in lipid metabolites between LH (Daodi) and other origins. And 39 characteristic compounds such as TAG 16:0/18:0/18:2, TAG 18:0/18:1/18:2, and LDGCC 15:2 could be used as the markers to identify the geographical origin of lily. This study established a new method to identify the origin traceability of lily in different production areas, and provided a theoretical basis to evaluate the nutritional value of lilies from different origins. [Display omitted] • PI and PE are the main phospholipid components in lilii bulbus. • Lipid metabolomics can distinguish the geographical origin of lilii bulbus. • Thirty-nine characteristic components (VIP greater than 1) were obtained. • TAG compounds are the characteristic compounds to distinguish lilii bulbus origins.

Lilii bulbus is an important food in China with medicinal and edible functions, and its quality and price are closely related to its geographical origin. In this work, 4 stable isotopes (δ13C, δ15N, δ2H and δ18O) and 41 mineral elements of lilii bulbus samples from 11 origins and 4 species were collected and combined with chemometrics to identify origins and species. ANOVA and principal component analysis (PCA) showed significant differences (P < 0.05) in stable isotopes and multiple elements in lilii bulbus samples from different origins, and Cu, Zn, K, δ18O, Sr and Li are important contributors to the classification. Partial least squares discriminant analysis (PLS-DA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were used to classify different species of lilii bulbus with good classification performance, while indicating that K, Ca, Na and Mg elements could be used as effective elements for species classification. The external validation model of OPLS-DA showed high accuracy (>89%) for lilii bulbus species classification. This study shows that stable isotopes and multi-elemental combined chemometrics provide an effective method for lilii bulbus origin and species identification. [Display omitted] • Geographic identification of lilii bulbus with stable isotopes and elements is feasible. • δ18O are useful factors for identifying lilii bulbus's geographical origin. • K, Ca, Na and Mg are important factors to distinguish different species of lilii bulbus samples. • The accuracy of OPLS-DA in discriminating lilii bulbus species is more than 89.61%.

Lilii Bulbus is a commonly used Chinese herbal medicine with both medicinal and edible values, while the market products usually has the problem of sulfur fumigation. Therefore, the quality and safety of Lilii Bulbus products deserve attention. In this study, ultra-high performance liquid chromatography-time of flight-tandem mass spectrometry(UPLC-Q-TOF-MS/MS) was combined with principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) to analyze the differential components of Lilii Bulbus before and after sulfur fumigation. We identified ten markers generated after sulfur fumigation, summarized their mass fragmentation and transformation patterns, and verified the structures of phenylacrylic acid markers of sulfur fumigation. At the same time, the cytotoxicity of the aqueous extracts of Lilii Bulbus before and after sulfur fumigation was evaluated. The results showed that in the concentration range of 0-800 mg·L~(-1), the aqueous extract of Lilii Bulbus after sulfur fumigation had no significant effect on the viability of human liver LO2 cells, human renal proximal tubular HK-2 cells, and rat adrenal pheochromocytoma PC-12 cells. Moreover, the viability of the cells exposed to the aqueous extract of Lilii Bulbus before and after sulfur fumigation showed no significant difference. This study identified phenylacrylic acid and furostanol saponins as markers of sulfur-fumigated Lilii Bulbus for the first time, and made clear that proper sulfur fumigation of Lilii Bulbus would not produce cytotoxicity, providing a theoretical basis for the rapid identification and quality and safety control of sulfur-fumigated Lilii Bulbus.

To investigate the potential molecular mechanism of the combination of Platycodonis Radix and Lilii Bulbus with the homology of medicine and food in the treatment of pneumonia by means of network pharmacology and in vitro verification experiment. Under the condition of bioavailability(OB)≥30% and drug-like(DL)≥0.18, the active components of Platycodonis Radix and Lilii Bulbus were screened in TCMSP database; the prediction targets of active components were searched from TCMSP, DrugBank and other databases, and the potential targets of pneumonia were obtained through GeneCards and OMIM database. The common targets were obtained by the intersection of drug and disease targets. The PPI network of common targets was constructed by STRING 11.0, and the core targets were obtained by topological analysis. Then the core targets received GO and KEGG analysis with use of WebGestalt and Metascape. The &quot;component-target-pathway&quot; network was constructed with the help of Cytoscape 3.7.1 software, and the component-target molecular docking verification was carried out with Discovery Studio 2016 software. Finally, the core targets and pathways were preliminarily verified in vitro. In this study, 12 active components were screened, 225 drug prediction targets and 420 potential diseases targets were obtained based on data mining method, and 14 core targets were obtained by topological analysis, including TNF, MMP9, AKT1, IL4 and IL2. The enrichment results of GO and KEGG showed that &quot;Platycodonis Radix and Lilii Bulbus&quot; drug pair may regulate inflammation, cell growth and metabolism by acting on 20 key signaling pathways such as TNF and IL-17, thereby exerting anti-pneumonia effects. The results of molecular docking showed that 12 active components had good binding ability with 14 core targets. In vitro experiment results showed that the core components of &quot;Platycodonis Radix and Lilii Bulbus&quot; drug pair could inhibit the expression of MMP9 and TNF-α by regulating TNF signal pathway. This study confirmed the scientificity and reliability of the prediction results of network pharmacology, and preliminarily revealed the potential molecular mechanism of the compatibility of Platycodonis Radix and Lilii Bulbus in the treatment of pneumonia. It provides a novel insight on systematically exploring the mechanism of the compatible use of Platycodonis Radix and Lilii Bulbus, and has a certain reference value for the research, development and application of new drugs.

To clarify the species and preparation of " Baihe"( Lilii Bulbus),a traditional Chinese medicine,we investigated the relative ancient Chinese literature on this medicine. The study concluded that Lilium brownii var. viridulum is the authentic lily for medical use. In the Ben Cao Yan Yi and some medical books in the Ming and Qing Dynasties,L. lancifolium( Juandan) was also mistakenly used as genuine lily,but most doctors believe that this variety should not be used for medicinal purposes; L. pumilum( Shandan)began to be used as a medicine from Ri Hua Zi Ben Cao,but mainly for surgery,the effect is also different from L. brownii var. viridulum. We suggested Shandan be used as the species for another medicine as " Hong Bai He( red lily) " due to its red flower. All above three species recorded in the Chinese Pharmacopoeia are not corresponded to the condition of ancient doctors' uses. Therefore,as for developing of traditional classical formula,L. brownii var. viridulum should be chosen and used as Baihe. The birth places for Baihe include Gansu,Hubei,Anhui and Shandong province. The drug preparations of Baihe include crude medicine,roasting and steaming,which preparation should be chosen depends on the formula which contains Baihe.

The potential role of total saponins extracted from Lilium lancifolium bulbs (TSLL) on the proliferation, apoptosis, migration and invasion of human lung cancer A549 cells and its possible mechanism were discussed. Effect of TSLL on proliferation of A549 cells were detected by CCK-8, clone formation assay and EdU staining. Effect of TSLL on apoptosis morphology of A549 cells was observed by fluorescence microscope using Annexin V/PI double staining and Hoechst 33342 staining. Effect of TSLL on cell migration and invasion was detected by Transwell migration test and Transwell invasion test, respectively. Western blot was used to detect TSLL on the expression change of intracellular associated proteins. Results showed that TSLL intervention in A549 cells within 24, 48 or 72 h significantly inhibited cell growth, and its IC₅₀values were about 229, 173 and 71 mg·L⁻¹, respectively. TSLL significantly reduced the clone formation rate of A549 cells and decreased the DNA synthesis rate of A549 cells in a concentration dependent manner. TSLL induced A549 cells apoptosis and reduced the migratory behavior of A549 cells. TSLL decreased invasion of A549 cells to the artificial basement membrane. The expression level of intracellular PCNA and the ratio of Bcl-2/Bax protein were down-regulated and procaspase 3 was activated. In addition, TSLL had no obvious effect on epithelial mesenchymal transition (EMT) related marker proteins E-cadherin and vimentin expression. The above results indicated that TSLL possess inhibitory effects against proliferation, migration and invasion of lung cancer A549 cells and apoptosis-induced effect. The anti-proliferation effect of TSLL is very likely by inhibiting intracellular DNA synthesis through reducing the expression of PCNA in lung cancer cells. And the apoptosis induction of TSLL on lung cancer cells is associated with the regulation of Bcl-2 and Bax proteins expression. Nevertheless, there is no incontestable correlation between anti-invasion and metastasis effects of TSLL and EMT in lung cancer cells., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Chinese Pharmaceutical Association.)

Lilii Bulbus, which comes from many medicinal plants，is a frequently-used traditional Chinese medicine，the records in previous herbal literatures of it's origin and quality were inconstant. To trace back it's sources, we conducted a systematical study on it's origin and quality by textual research and investigation in this paper,The result showed that the origins of Lilii Bulbus are mainly source from white-flowers, red-yellow-flowers and red-flowers of Lilium， L. brownii var. viridulum, which were believed authentic or good quality in all previous herbal literatures,and L. pumilum and L. concolor which belong to white-flowers,and L. lancifolium which belong to red-yellow-flowers were believed low-quality and unfit for medicinal uses, or they were listed below and often have different effect with L. brownii var. viridulum. Among them, only L. concolor does not belong to Lilii Bulbus according to Chinese Pharmacopeia (2015 edition), The mainstream varieties of Lilii Bulbus became L. lancifolium now according to our practical investigation, which were very different from previous herbal literatures. Although chemical and pharmacological studies provided a reference for L. lancifolium，we should respect the actual records of the previous herbal literatures，the research of material foundation of efficacy should be more sufficient，and provide science evidence for clinical application of different species of Lilii Bulbus., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Chinese Pharmaceutical Association.)
