A new genus and species of terrestrial freshwater crab, Calcipotamon puglabrum gen. nov. et sp. nov., is described from the limestone forests Changjiang, Hainan Island, China, based on morphology mitochondrial 16S rDNA sequences. The closest to Neotiwaripotamon Dai & Naiyanetr, 1994, Tiwaripotamon Bott, 1970, but differs in a combination carapace, third maxilliped, ambulatory leg male gonopod characters. Molecular analysis shows that closely related with not clustered within other...
Six new meroterpenoids, chrodrimanins K–N (1–4), including two uncommon chlorinated ones (1 and 2), verruculides B2 (5) B3 (6), as well seven known (7–13), were isolated from the fermentation broth of Penicillium sp. SCS-KFD09 a marine worm, Sipunculus nudus, Haikou Bay, China. The structures absolute configurations compounds unambiguously elucidated by spectroscopic data, X-ray diffraction analysis, ECD spectra analysis along with quantum calculations. In addition, crystal previously...
Abstract Backgroud Aquilaria sinensis (Lour.) Spreng is one of the important plant resources involved in production agarwood China. The resin collected from wounded trees has been used Asia for aromatic or medicinal purposes ancient times, although mechanism underlying formation still remains poorly understood owing to a lack accurate and high-quality genetic information. Findings We report genomic architecture A. by using an integrated strategy combining Nanopore, Illumina, Hi-C sequencing....
Eight new alkaloids, 3β-n-butylstemonamine (1), 8-oxo-3β-n-butylstemonamine (2), 3-n-butylneostemonine (3), 10-epi-3-n-butylneostemonine (4), 8-oxo-oxymaistemonine (5) protostemonine N4-oxide (6), (19S)-hydroxy-21-methoxystemofoline (7), and parvistemonine A (8), were isolated from the roots of Stemona parviflora, together with 17 known alkaloids. The structures alkaloids elucidated based on a comprehensive spectroscopic data analysis. absolute configurations 1–4 determined by ECD exciton...
Autism, with a global morbidity of approximately 0.6% annually, significantly burdens on families and society. A predominant characteristic among autistic children is intestinal dysfunction, generating nutrient absorption issues. This often causes vitamin mineral deficiencies, which impacts neurological development. To address this, we have developed comprehensive nutritional supplement containing compound vitamins, minerals, gut bacteria. The aim this study to investigate the behavioral...
Introduction Island ecosystems, due to their geographical isolation and unique environmental conditions, often serve as natural laboratories for ecological research are also sensitive global climate change biodiversity loss. The allometric relationship between plant height-diameter reflects the adaptive growth strategy of plants under different particularly in response biomechanical constraints (e.g., wind resistance) resource availability. This study aims explore key driving factors...
Introduction Island biogeography theory posits that both island area and isolation significantly influence species distribution patterns community structure. This study investigates the effects of on plant structure, specifically focusing variation in richness abundance among different life forms (i.e., trees shrubs) tropical islands South China Sea. Methods We surveyed woody plants collected soil samples from 20 Sea, analyzing how area, isolation, climate factors communities across (trees...
Polygonatum cyrtonema Hua is cultivated for its edible and medical value. The steam-processed rhizome of P. the main form daily consumption it has been used traditionally in tonics treating various age-related disorders. aim our study was to compare physicochemical properties antioxidant activity polysaccharides respectively extracted from crude Cyrtonema (PCPC), (PCPS), explore a possible underlying mechanism.The PCPC with molecular weight 4.35 × 103 Da mainly consisted fructose trace...
Four picrotoxane-type sesquiterpenes, dendroterpene A–D (1–4), together with four known compounds (5–8), were isolated from the stems of Dendrobium nobile Lindl. Their structures elucidated by spectroscopic analysis, X-ray diffraction analysis ECD data according to Klyne's lactone sector rule, and quantum calculation. Compounds 1 2 are two new sesquiterpenes a carbon skeleton containing formamide group, which may be derived previously reported dendrobiumane B C(9)-C(11) bond cleavage. 3, 5,...
Abstract Two new guaiane‐type sesquiterpenoids, valerol A ( 1 ) and kessyl 3‐acetate 2 ), together with nine known compounds, valeracetate 3 anismol 4 orientalol C 5 spatulenol 6 α ,10 ‐epoxyaromadendrane 7 (+)‐8‐hydroxypinoresinol 8 pinorespiol 9 pinoresinol 4‐ O ‐ β D ‐glucopyranoside 10 8‐hydroxypinoresinol 4′‐ 11 were isolated from the roots of Valeriana officinalis. The structures relative configurations elucidated on basis spectroscopic methods (1D‐ 2D‐NMR, MS, UV, IR). These compounds...
Three new lanostanoid triterpenes, 3β,7β,15β-trihydroxy-11,23-dioxo-lanost-8,16-dien-26-oic acid (1), methyl ester (2), and 3β,15β-dihydroxy-7,11,23-trioxo-lanost-8,16-dien-26-oic (3) were isolated from the EtOAc extract of fruiting bodies Ganoderma tropicum. Their structures elucidated on basis 1D 2D NMR spectroscopy as well MS. The bioassay inhibitory activity against acetylcholinesterase (AChE) these isolates was evaluated compound 2 exhibited definite AChE.
Thirteen new sesquiterpenoids were isolated from the stems of <italic>Daphne aurantiaca</italic> diels. Some compounds showed definite anti-HIV activities.
Three new lanostanoid triterpenes—ganotropic acid (1), 3β,7β,15α,24-tetra- hydroxy-11,23-dioxo-lanost-8-en-26-oic (2) and 3β,7β,15α,28-tetrahydroxy-11,23- dioxo-lanost-8,16-dien-26-oic (3)—were isolated from the n-BuOH extract of fruiting bodies mushroom Ganoderma tropicum. Their structures were elucidated by 1D 2D NMR spectroscopy, as well HR-EI-MS data.
A new tetracyclic indole alkaloid, 17-O-methyl-3,4,5,6-tetradehydrogeissoschizine, together with seven known ones, were isolated from the aerial part of Uncaria rhynchophylla. Their structures unambiguously elucidated by spectroscopic methods and comparing literature data. Among them, compounds 1, 3, 4 6-8 showed potent to moderate antinematode activities against Panagrellus redivevus at a concentration 250 μg/mL.
Dragon's blood collected from the genus Dracaena is used as a renowned traditional medicine in various cultures worldwide. However, genetics of and formation mechanism dragon's remain poorly understood.
