As an edible and medicinal fungus, Dictyophora indusiata is well-known for its morphological elegance, distinctive taste, high nutritional value, therapeutic properties. In this study, eighteen compounds (1–18) were isolated identified from the ethanolic extract of D. indusiata; four (1–4) previously undescribed. Their molecular structures absolute configurations determined via a comprehensive analysis spectroscopic data (1D/2D NMR, HRESIMS, ECD, XRD). Seven examined their anti-inflammatory...
Breast cancer is one of the most common cancers and second leading cause mortality in women worldwide. Novel therapies chemo-therapeutic drugs are urgently needed to be developed for treatment breast cancer. Increasing evidence suggests that fatty acid synthase (FAS) plays an important role cancer, expression FAS significantly higher human cells than normal cells. Tannic (TA), a natural polyphenol, possesses significant biological functions, including bacteriostasis, hemostasis,...
Bamboo shoots are a delicacy in Asia. Two novel compounds, adenine-(1′R,2′R,3′R)-cyclic butanetetraol carbonate (16) and (−)-(7R,8S)-(4-hydroxy-3-methoxyphenylglycerol 9-O-β-d-[6-O-4-hydroxy-3-methoxybenzoyl])-glucopyranoside (20), together with 12 known nucleosides (1–12), 3 amino acids (13–15), β-carboline (17), 2 megastigmane glycosides (18, 19) were isolated from bamboo (Phyllostachys pubescens). Their structures absolute configurations rigorously determined by detailed spectroscopic...
Bamboo and rattan are widely grown for manufacturing, horticulture, agroforestry. production might help reduce poverty, boost economic growth, mitigate climate change, protect the natural environment. Despite progress in research, sufficient molecular genomic resources to study these species lacking. We launched Genome Atlas of Rattan (GABR) project, a comprehensive, coordinated international effort accelerate understanding bamboo genetics through genome analysis. GABR includes 2 core...
The utilization of natural products in food preservation represents a promising strategy for the dual benefits controlling foodborne pathogens and enhancing nutritional properties foods. Among phytonutrients, flavonoids have been shown to exert antibacterial effects by disrupting bacterial cell membrane functionality; however, underlying molecular mechanisms remain elusive. In this study, we investigated effect quercetin on permeability
Bamboo vinegar is a liquid biomass with huge yield and complex chemical composition. At present, the relative quantification of bamboo has been investigated in most studies. To analyze twelve compounds from simultaneously, gas chromatography-mass spectrometry an external standard method were used to develop analytical method. In this method, chromatographic separations all above 1.5. The linear range was between 0.100 10.000 mg/L, coefficient determination (R2) 0.9981 0.9997, indicating good...
Tannic acid inhibits lipid accumulation in the early stage of 3T3-L1 preadipocytes differentiation by down-regulating PPARγ.
Bamboo shoot is a delicious and nutritious forest vegetable. It has been found that bamboo shoots collected from low-light environments have less bitter taste. The molecular mechanism of light in the regulation substance accumulation still unclear. In this study, we applied shading treatment to Pleioblastus amarus preharvesting period. reduction bitterness intensity was confirmed by sensory test. An integrated metabolomic transcriptomic analysis performed on P. grown under normal growing...
The glutinous rice dumpling named “Zongzi” in Chinese is a type of traditional food that popular East Asian countries. made and wrapped the leaves Indocalamus latifolius McClure as packaging material. Four new compounds, latifoliusine A (2), (7S,8R) syringylglycerol-8-O-4′-sinapyl ether 4-O-β-d-glucopyranoside (7), (7S,8S) 7-O-β-d-glucopyranoside (8), (7R,8S) (10), along with six known compounds (1, 3–6 9) were isolated from I. leaves. structures relative configurations determined by...
A large amount of waste from Bambusa chungii culms is generated the bamboo pulping industry, causing disposal problems. Nevertheless, are a suitable source functional ingredients, such as antioxidant compounds. However, because high compactness and tightness in their material structure, obtaining phytochemicals using conventional organic solvent extraction methods can be inefficient. In this research, we developed pressurized hot water (PHWE) method to recover 19 target phenolic compounds...
Azadirachta indica (neem) is the only source of azadirachtin, which known for its insecticide activity. Melia azedarach a related species A. indica, widely distributed in south China. In this study, leaf transcriptomes these two Meliaceae plants were sequenced. More than 40 million clean reads generated from each library. About 80 % mapped to neem genome, while 93 M. assembled transcripts and unigenes dateset. After mapping assembly, 225,972 91,607 obtained 1179 new genes detected....
Abstract An analytical method for the simultaneous determination of ten major functional flavonoids (isoorientin, orientin, vitexin, isovitexin, apigenin, luteolin, tricin, quercetin, rutin, and kaempferol) in different bamboo species was developed by liquid chromatography-tandem mass spectrometry. Chromatographic separation carried out on a reversed-phase C-18 column with acetonitrile water as mobile phases. Detection performed negative ion electrospray ionization mode using multiple...
Neem (Azadirachta indica) extract is well-known as a natural pesticide for the control of agricultural pests. Azadirachtin A and its structural analogues are considered active compounds. However, amounts azadirachtins varies in neem extracts, providing variety insecticidal activities. In this study, novel method automated online solid-phase extraction coupled with liquid chromatography/quadrupole-time-of-flight mass spectrometry (SPE-LC-Q-TOF-MS) was developed validated simultaneous...
Purpose: To develop a method to identify and quantify the compounds in shoots of four Phyllostachys bamboo species (Gramineae prominens W. Y. Xiong, Gramineae iridescins C. Yao pubescens (Carr.)
