Aims: The aims of this study were to elucidate the pythochemical compounds from the leaf of mangrove (Barringtonia asiatica L. (Kurz) colleceted from the coast of Pangandaran Regency, West Java, Indonesia as well as its antioxidant activity profile. Study Design: The study was designed experimentally with two replication (duplo) for the extraction preparation and analyzed statistically using regression linear for the determination of Inhibition Concentration at 50% or IC50. Place and Duration of Study: Sample were collected from the mangrove ecotourism site at Pangandaran Regency, West Java, Indonesia. The experimental study was performed at the Tropical Marine and Fisheries Laboratory, Fisheries Department, PSDKU Padjadjaran University, Indonesia. Methodology: The identification of pythochemical contents of the leaf was carried out qualitatively with the principle of formation of precipitate, color and foam. The extraction was performed accordingly using three different types of solvent, n-hexane, ethyl acetate and methanol. Lastly, the antioxidant activity was tested using DPPH (1,-diphenyl-2-picrylhydrazyl) method and IC50 were analyzed subsequently. Results: Based on the results of the research that has been carried out, it can be concluded that the leaves of Barringtonia asiatica L. (Kurz) contain bioactive compounds in the form of tannins and saponins. The methanol extract of Barringtonia asiatica L. (Kurz) was proven to have moderate strength antioxidant activity with IC50 value of 125.87 ppm. Conclusion: this results concluded that different geographic region can influence the phytochemical constituent of the of Barringtonia asiatica L. (Kurz). Furthermore, this doesn’t hindered its antioxidant activity potential as it still proven to have a relatively medium antioxidant activity.

Mangrove plants play an important role in the remediation of heavy-metal-contaminated estuarine and coastal areas

Context Among the plants in the genus Barringtonia (Lecythidaceae) used as traditional medicines to treat arthralgia, chest pain, and haemorrhoids in Indonesia, Barringtonia racemosa L. and Barringtonia acutangula (L.) Gaertn. have demonstrated anti-inflammatory activity in systemic inflammatory models. Objective The anti-inflammatory activity of Barringtonia angusta Kurz has not been investigated. We prepared a methanol extract of the leaves and stems of B. angusta (Ba-ME) and systemically evaluated its anti-inflammatory effects in vitro and in vivo. Materials and methods RAW264.7 cells stimulated with LPS or Pam3CSK4 for 24 h were treated with Ba-ME (12.5, 25, 50, 100, and 150 µg/mL), and NO production and mRNA levels of inflammatory genes were evaluated. Luciferase reporter gene assay, western blot analysis, overexpression experiments, and cellular thermal shift assay were conducted to explore the mechanism of Ba-ME. In addition, the anti-gastritis activity of Ba-ME (50 and 100 mg/kg, administered twice per day for two days) was evaluated using an HCl/EtOH-induced gastritis mouse model. Results Ba-ME dose-dependently suppressed NO production [IC50 = 123.33 µg/mL (LPS) and 46.89 µg/mL (Pam3CSK4)] without affecting cell viability. Transcriptional expression of iNOS, IL-1β, COX-2, IL-6, and TNF-α and phosphorylation of Src, IκBα, p50/105, and p65 were inhibited by Ba-ME. The extract specifically targeted the Src protein by binding to its SH2 domain. Moreover, Ba-ME significantly ameliorated inflammatory lesions in the HCl/EtOH-induced gastritis model. Discussion and conclusions The anti-inflammatory activity of Ba-ME is mediated by targeting of the Src/NF-κB signalling pathway, and B. angusta has potential as an anti-inflammatory drug.

Our examination of high molecular weight polyphenolic constituents in the leaves of Barringtonia racemosa of the family Lecythidaceae uncovered 5 previously undescribed ellagitannins. One, barringtin M1 (1), among them was a hydrolysable tannin monomer, while remaining 4, barringtins D1 (2), D2 (3), D3 (4), and barricyclin D1 (5), were all dimers. Barricyclin D1 had a first macrocyclic structure formed from casuarictin (6) and tellimagrandin I (7), and the other ellagitannins had structures related to 5. Two additional known phenolics, valoneic acid dilactone (8) and schimawalin A (9), were also isolated from the leaves. These results suggested that the leaves of B. racemosa are a natural resource rich in hydrolysable tannin oligomers.

The study was conducted to identify the phytochemical contents in the seeds of fish poison tree, Barringtonia asiatica (L.) Kurz. The qualitative and quantitative analysis were ascertained using standard conventional methods and gas chromatography–mass spectroscopy (GC-MS) technique. Phytochemical screening revealed the presence of saponins, alkaloids, cardiac glycosides, flavonoids, terpenoids, coumarin and tannins in the seeds. In addition, the seed contained 42 compounds which includes Vitamin E, (45.89%), fatty acid esters (LAEE, 40.30%; PAEE, 10.24%; (E)-9-ODAEE, 6.73%) and sterols (chondrillasterol, 14.20%; lanosterol, 7.29%; and stigmasterol, 7.02%). Furthermore, chemical components such saponins, alkaloids, and cardiac glycosides present in the seed were found positive for biopesticidal activity. The analysis confirmed that fish poison tree seed is a potential source of bioactive substances that may support pharmaceutical uses and biopesticide production.

The eastern state of Odisha, India is well known for its rich microlithic assemblages; over 400 sites have been reported, including some with tools for heavy-duty tasks. However, due to the lack of associated vertebrate fossils from stratified horizons and absolute dates, their antiquity and associated environments are yet to be established. We report here, for the first time, in situ fossils of a ruminant 14C dated to 17,875 cal BP associated with microliths from a stratified Quaternary sequence exposed at Pratappur, District Mayurbhanj, Odisha. The dental remains of ruminants are taxonomically identified to be those of the cervid Rusa unicolor (sambar) and an unidentified bovid. Stable carbon and oxygen isotope values (δ13C = 1.9‰; δ18O = −1.83‰, VPDB) on the Rusa unicolor tooth reveal that it was a C4 grazer and lived in an arid environment during the end of the Last Glacial Maximum. However, the bovid-yielding carbonaceous sediments that lie immediately above the R. unicolor horizon have yielded a large number of pollen and spores, belonging to moist deciduous forest suggesting moderate rainfall. Pollens belong to brackish mangrove Nypa and Barringtonia indicating tidal influence and the existence of a coastal environment nearby.

Barringtonia augusta methanol extract (Ba-ME) is a folk medicine found in the wetlands of Thailand that acts through an anti-inflammatory mechanism that is not understood fully. Here, we examine how the methanol extract of Barringtonia augusta (B. augusta) can suppress the activator protein 1 (AP-1) signaling pathway and study the activities of Ba-ME in the lipopolysaccharide (LPS)-treated RAW264.7 macrophage cell line and an LPS-induced peritonitis mouse model. Non-toxic concentrations of Ba-ME downregulated the mRNA expression of cytokines, such as cyclooxygenase and chemokine ligand 12, in LPS-stimulated RAW264.7 cells. Transfection experiments with the AP-1-Luc construct, HEK293T cells, and luciferase assays were used to assess whether Ba-ME suppressed the AP-1 functional activation. A Western blot assay confirmed that C-Jun N-terminal kinase is a direct pharmacological target of Ba-ME action. The anti-inflammatory effect of Ba-ME, which functions by β-activated kinase 1 (TAK1) inhibition, was confirmed by using an overexpression strategy and a cellular thermal shift assay. In vivo experiments in a mouse model of LPS-induced peritonitis showed the anti-inflammatory effect of Ba-ME on LPS-stimulated macrophages and acute inflammatory mouse models. We conclude that Ba-ME is a promising anti-inflammatory drug targeting TAK1 in the AP-1 pathway.

Barringtonia racemosa leaf water extract (BLE) had been shown to have high gallic acid (GA) content and BLE has been postulated to have anti-proliferative effects towards colorectal cancer. This study aims to further investigate the mechanism underlying the anti-proliferative effect of BLE in Caco-2 cells and to determine if GA is responsible for the observed effects. Both BLE and GA inhibited Caco-2 cells in a dose-dependent manner. Cells exposed to IC50 concentration of BLE and GA showed reduced antioxidant activities. GA-treated Caco-2 cells experienced higher oxidative stress compared to cells treated with BLE. Both BLE and GA significantly up-regulated the expression of SLC2A1. BLE but not GA, significantly down-regulated the expression of ADH4. Meanwhile, GA but not BLE, significantly up-regulated AKRIB10 and GLO1 but significantly down-regulated HAGH. Alterations in gene expression were coupled with changes in extracellular glucose and pyruvate levels. While BLE decreased intracellular pyruvate, GA did the opposite. Both intracellular and extracellular D-lactate were not affected by either BLE or GA. GA showed more pronounced effects on apoptosis while BLE irreversibly reduced cell percentage in the G0/G1 phase. In conclusion, this study demonstrates the multiple-actions of BLE against Caco-2 cells, potentially involving various polyphenolic compounds, including GA.

This study was conducted to examine the effect of “keben” seed Baringtonia asiatica (L.) Kurz on mortality of flea ( Coccus viridis ) found in Coffea sp. Experimental methods with Complete Random Design (CRD) was used in this study. Five doses of “keben” seed extract (0.2%, 0.4%, 0.6% 0.8% and 0.0%) were used.

Among the concentration used, it was found that concentration at 0.4% more effective than other concentrations. Consentration at 0.4% was killed 100% of Coccus viridis population in 3 days. Key words: Barringtonia asiatica , Coccus viridis, Concentration of seed extract.

Sumardi, Basyuni M, Wati R. 2018. Antimicrobial activity of polyisoprenoids of sixteen mangrove species from North Sumatra, Indonesia. Biodiversitas 19: 1243-1248. Mangroves including those that are distributed in the coast of North Sumatra contain polyisoprenoid with varying levels of polyprenol and dolichol constituents. Differences in polyisoprenoid levels were closely related to the salinity of sea but the information about their biological activities is scarce. The present study aimed to describe the biological activities, antimicrobial, antioxidant, and antifungal effects of polyisoprenoid extracts from sixteen mangrove species of North Sumatra, Indonesia. Polyisoprenoids were isolated from mangrove leaves and tested for their antimicrobial activity against Escherichia coli, Staphylococcus aureus, and Candida albicans. Meanwhile, their antioxidant activity was represented by their capacity in scavenging DPPH (2,2-diphenyl-1-picrylhydrazyl) free-radical agents. The most predominant polyisoprenoids found in sixteen mangrove leaf extracts was dolichols (75%). Polyprenols-dominant species, Acacia auriculiformis, Hibiscus tiliaceus, Pongamia pinnata, and Ricinus communis, and dolichols-dominant species, Avicennia lanata, Av. marina, Av. officinalis, Barringtonia asiatica, Bruguiera gymnorrhiza, Calophyllum inophyllum, Nypa fruticans, and Pandanus odoratissimus, inhibited the growth of E. coli and S. aureus. However, the antioxidant activity of those sixteen mangrove species was of a weak category. Surprisingly, all other mangroves polyisoprenoid extracts did not inhibit C. albicans growth. This study suggested that polyisoprenoids in mangroves have potential antibacterial properties to be developed further.

Basyuni M, Wati R, Sagami H, Sumardi, Baba S, Oku H. 2018. Diversity and abundance of polyisoprenoid composition in plant species from North Sumatra, Indonesia. Biodiversitas 19: 1-11. The distribution and abundance of polyprenols (pol) and dolichols (dol) in the leaves and roots of fourteen coastal plants from North Sumatra, Indonesia were analysed using two-dimensional thin layer chromatography. In the leaves, with respect to the distribution of pol and dol were detected and categorized into three-types. In type-I, the predominance of dol over pol, was observed in Barringtonia asiatica, Calophyllum inophyllum, Pandanus odoratissimus, and Stachytarpheta jamaicensis. In type-II, the presence of both pol and dol, was observed in Casuarina equisetifolia, Melastoma candidum, Morinda citrifolia, Scyphiphora hydrophyllacea, Sesuvium portulacastrum and Terminalia catappa. In type-III, the predominance of pol over dol, was observed in Acacia auriculiformis, Hibiscus tiliaceus, Ricinus communis, and Pongamia pinnata. However, in the roots, a type-I distribution was observed in eleven species, while three species, A. auriculiformis, M. candidum, and M. citrifolia, corresponded to a type-II distribution instead of type-III. The diversity of polyisoprenoid composition in the leaves was noted, whereas 79% of root tissues indicated that dol occur more abundantly than pol. The range of the contents of polysioprenoid was 12-300 mg/g dw. The present study indicated that pol and dol could be useful in the classification of mangroves and other coastal forests and in phylogenetic studies. The diversity and presence of polyisoprenoids in coastal plants suggested that plant polyisoprenoids are chemotaxonomically important.

Floodplain forests serve a critical function in flood regulation and the global carbon (C) cycle due to their important role in C sink management. Barringtonia acutangula , a tree species adapted to floodplains has been managed traditionally over millennia as family and community forest in North East India. Prevailing traditional management of the Barringtonia forest restricts felling of trees while promoting uses of tree branches in fishery management and fuel wood production. Such management systems might have helped in sustaining floodplain family forests with a steady stock of biomass. However, our knowledge of their role in biomass stocks and C storage is still scanty. Therefore, the present study was undertaken to estimate the biomass and carbon stocks of Barringtonia forests and to understand their role in carbon sink management. The floodplain forest at the study site was stocked with 3204 trees ha −1 of Barringtonia . Allometric models were developed using harvested tree, and these were used for estimation of biomass and vegetation carbon stocks. Among the various models tested the power model using diameter at breast height (DBH) as an independent variable fitted tree biomass in different tree components (bole, sprout, branch and leaves) adequately. Total dry above ground biomass (AGB) estimated at 552 ± 23 Mg ha −1 in the Barringtonia floodplain forests was much larger than AGB reported for various forest types and agroforestry systems in North East India. Biomass allocation patterns revealed that out of the total biomass, the bole contributed the highest proportion (45%) followed by sprouts (27%), branches (24%) and leaves (4%). The above-ground carbon stock was estimated at 263 ± 11 Mg ha −1 . The quantity of biomass stock and the carbon storage in vegetation cover of Barringtonia forest suggest its direct influence on local, regional and even global climate.

Pachyrhynchus sonani Kono, 1930, a legally protected species in Taiwan, is endemic to Lanyu Island (Orchid Island) and Ludao Island (Green Island). Because of its unclear life history, the host and immature stages of this species in the wild have not so far been recorded. On Lanyu Island, we recently identified Barringtonia asiatica as a host plant of P. sonani, with several larvae feeding on its xylem. Herein, we describe its biology and the habitat surrounding the host plant.

Objective. To ascertain the essential oil phytochemicals of the leaf and to test for the antibacterial and antioxidant properties of dichloromethane crude extract of Barringtonia asiatica leaf. Methods. The phytochemical screening of essential oils, extraction by hydrodistillation using the Clevenger apparatus, and analysis performed by gas chromatography equipped with a flame ionization detector (GC-FID). Antibacterial activity and the inhibition rate (mm) were determined using the agar disc method against four bacterial strains using tetracycline as positive control. The antioxidant potential of dichloromethane crude extract was investigated spectrophotometrically using 1,1-diphenyl-2-picrylhydrazyl. Results. The essential oil properties were reasonable with major phytochemicals like uncineol 30.9%, eicosane 27.4%, eicosane 21.6%, and 4-propyl-guaiacol 14.05%. The antibacterial activity of the dichloromethane crude extract showed broad-spectrum activity against Salmonella typhi, Escherichia coli, Staphylococcus aureus, and Klebsiella pneumoniae with inhibition value ranges between 2.50 ± 0.10 mm and 5.00 ± 0.06 mm. The dichloromethane crude extract exhibited strong antioxidant activities when compared to the standard. Conclusions. These results suggest that the leaves of Barringtonia asiatica is composed of essential compound as well as antibacterial and antioxidant properties from the crude extract; these are possible due to the presence of some bioactive compounds in the crude extract. The species also showed a reasonable amount of natural products in the essential oils from the hydrodistillation which can as well be used in the cosmetics and food industries.

Research is ongoing to develop and discover new medicinal products and new medicinal crops, as evidenced by a rapid increase in the number of scientific publications. Malaysia and the tropical regions are rich in flora and fauna, however, only a limited number of species have been scientifically researched and fully commercialised. This review described an indigenous plant named Barringtonia, which is less researched but nonetheless has great potential to be developed and commercialised as medicinal crops. Barringtonia is a genus belonging to the family of Lecythidaceae. Barringtonia spp. are perennial and evergreen plants with fibrous fruits. Different parts of these plants are widely employed as medicine to treat numerous diseases including gastrointestinal, respiratory, and skin diseases. The entire plant including the leaf, stem, stick, bark, fruit, and root, is utilised in traditional medicine. Although the majority of Barringtonia spp. are underutilised, several are still important particularly to some rural communities, as food or medicine. The current review is intended to comprehensively discuss the ethno-botanical uses of the genus Barringtonia by linking them with current scientific evidence. The review of literature is comprised of mainly the species B. racemosa, B asiatica, B. acutangula, B. edulis, B. procera, and B. novae-hiberniae. Phytochemicals present in these plants, particularly polyphenols and terpenoids, are discussed in detail in relation to their medicinal uses. This review also provides the nutritional benefits of Barringtonia spp. and identifies the needs for future research and development, domestication, and commercialisation of these plants.

Barringtonia asiatica was commonly used in various country of the world for treatment of liver disorder, diarrheal disease, eye disease, as well as antifungal and antibacterial, as well as chest pains and heart troubles. It was also considered a fish killer; this has been identified as a source of Natural products with potentials as an antitumor. The aim of the present review is to provide detailed information regarding geographical distribution, phytochemicals and pharmacological properties of this plant.

A novel actinomycete strain, designated GKU 128T, isolated from the roots of an Indian oak tree [Barringtonia acutangula (L.) Gaertn.] at Khao Khitchakut district, Chantaburi province, Thailand, was characterized by using a polyphasic approach. The strain formed a branched substrate and aerial mycelia which differentiated into straight to flexuous chains of smooth-ornamented spores. Analysis of the cell wall revealed the presence of meso-diaminopimelic acid and N-acetylmuramic acid in the peptidoglycan. The whole-cell sugars were glucose, madurose, mannose, rhamnose and ribose. Mycolic acids were absent. The major phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositolmannoside. The predominant menaquinones were MK-9(H6), MK-9(H8), MK-9(H0) and MK-9(H4). The major fatty acids were C16 : 0, C18 : 1ω9c and 10-methyl C18 : 0 (tuberculostearic acid). The genomic DNA G+C content was 70.5 mol%. Based on 16S rRNA gene sequence analysis, strain GKU 128T was closely related to the type strains of Actinomadura nitritigenes NBRC 15918T (99.2 % sequence similarity) and Actinomadura fibrosa JCM 9371T (98.7 %). The levels of DNA–DNA relatedness between strain GKU 128T and the closely related type species were less than 19 %. On the basis of phenotypic and genotypic characteristics, strain GKU 128T could be distinguished from its closely related type strains and represents a novel species of the genus Actinomadura , for which the name Actinomadura barringtoniae sp. nov. (=TBRC 7225T=NBRC 113074T) is proposed.

Background and Aims Root mechanical traits, including tensile strength (T-r), tensile strain (epsilon(r)) and modulus of elasticity (E-r), are key functional traits that help characterize plant anchorage and the physical contribution of vegetation to landslides and erosion. The variability in these traits is high among tree fine roots and is poorly understood. Here, we explore the variation in root mechanical traits as well as their underlying links with morphological (diameter), architectural (topological order) and anatomical (stele and cortex sizes) traits. Methods We investigated the four tropical tree species Pometia tomentosa, Barringtonia fusicarpa, Baccaurea ramiflora and Pittosporopsis kerrii in Xishuangbanna, Yunnan, China. For each species, we excavated intact, fresh, fine roots and measured mechanical and anatomical traits for each branching order. Key Results Mechanical traits varied enormously among the four species within a narrow range of diameters (

An examination of insect resistance was determined by several steps, i.e. standard sensitivity, resistance diagnosis, and determination of resistance level. Each phase was tested with feeding and residue contact methods at glass tube. Resistance ratio (RR) was determined by comparing LC50 value of field population with standard population. Field population of C. pavonana was classified resistant if it had RR 5 4. Biochemistry analysis of resistance was conducted to population of C. pavonana showing resistance to prophenophos insecticide. The activity analysis of acetylcholine esterase (ACHE), esterase, and Glutation Stransferase was done with spectrophotometer method. Insect which are resistant to prophenophos insecticide was tested for its sensitivity to Barringtonia asiatica seed extract. Result indicated that C. pavonana population from Pengalengan showed resistance to prophenophos synthetic insecticide. Using contact test, the highest resistance ratio value was 4.04, while by feeding assay the RR was 2.78. The study on biochemical resistance mechanisms of each field population of C. pavonana showed various activities of enzymatic detoxification. This could be due to the difference in the kind of insecticides exposed to each field population of C. pavonana. Since RR value from the contact test was higher than that of the feeding test, the resistance development of C. pavonana to synthetic insecticides was probably caused by physiological and biochemical changes in insect cuticle rather than the activity of detoxification enzyme. Methanolic seed extract of B. asiatica can be used as an alternative of resistance management of C. pavonana to prophenophos synthetic insecticide.

The use of synthetic chemicals to control plant pest should to be limited by utilizing natural products so that environmental contamination can be reduced and crop yields are safe to eat. The aim of this research is to get the effective concentration and application time of hutung fruit (Barringtonia asiatika) extract to control Maruca testulalis pod borer on long bean. The experiments design was complety randomized block design with treatments of 5% extract of hutung fruit with interval of time of two days application, 5% extract of nutmeg with time interval of three days application, 10% extract of nutmeg with time interval of two days application, 10% fruit extract hutung with a three-day application time interval. Two control treatments were 0.1% Decis insecticide with a three-day application time interval three replications and without any treatment. The result showed that 10% hutung fruit extract with two days application time interval was the best treatment and could decrease the intensity of Maruca testulalis pest borer attack on long bean up to 39,14%.

Using various chromatographic separation techniques, ten flavonoid glycosides, including six new compounds namely barringosides A-F (1-6), were isolated from a methanol extract of the Barringtonia acutangula leaves. The structure elucidation was confirmed by spectroscopic analyses, including 1D and 2D NMR, and HR ESI MS. Their inhibitory effects on LPS-induced NO production in RAW264.7 cells were also evaluated. Among the isolated compounds, quercetin 3-O-β-d-(6-p-hydroxybenzoyl)galactopyranoside (9) showed significant effect with an IC50 of 20.00±1.68µM. This is the first report of these flavonoid glycosides from Barringtonia genus and their inhibition on LPS-induced NO production in RAW264.7 cells was reported here for the first time.

A new species of fossil palm rhizome having root-mat under the organ genus Rhizopalamoxylon (Rhizopalmoxylon nypoides sp. nov.) is reported. The specimen shows the closest resemblance with the modern monotypic genus Nypa Wurmb of the Arecaceae. The specimen was collected from the late Maastrichtian–early Danian sediments of Deccan Intertrappean beds, Mothi, Sagar district, Madhya Pradesh, India. Nypa is a mangrove palm naturally found in estuaries and swamps of the tropical region and represents one of the oldest records of the genus from the Deccan Intertrappean beds of central India. The abundance of palms, including Nypa and previously recorded coastal and mangrove elements such as Acrostichum, Barringtonia, Cocos, Sonneratia and marine algae (Distichoplax and Peyssonellia) from the Deccan Intertrappean beds indicate marine influence and existence of tropical rainforest ecosystem in the vicinity of fossil locality in contrast to the deciduous forests occurring there at present.
