Postharvest pathogens can affect a wide range of fresh fruit and vegetables, including grapes, resulting in significant profit loss. Isoquinoline alkaloids of Mahonia fortunei, a Chinese herbal medicine, have been used to treat infectious microbes, which might be effective against postharvest pathogens. The phytochemical and bioactive investigation of this plant led to the isolation of 18 alkaloid...... hiện toàn bộ

Hypertension is a critical health problem and worse other cardiovascular diseases. It is mainly of two types: Primary or essential hypertension and Secondary hypertension. Hypertension is the primary possibility feature for coronary heart disease, stroke and renal vascular disease. Herbal medicines have been used for millions of years for the management and treatment of hypertension with minimum s...... hiện toàn bộ
Ypsiyunnosides A–E, Five New Cholestanol Glycosides from Ypsilandra yunnanensisNatural Products and Bioprospecting - Tập 6 - Trang 173-182 - 2016
Yu Chen, Yong-Ai Si, Wei Ni, Huan Yan, Xu-Jie Qin, Chang-Xiang Chen, Hai-Yang Liu
Phytochemical investigation on the whole plants of Ypsilandra yunnanensis was carried out for the first time and led to the isolation of five new cholestanol glycosides, ypsiyunnosides A–E (1–5), and one known analogue. Their structures were determined mainly by detailed spectroscopic analysis, including extensive 1D and 2D NMR, MS and UV, as well as chemical methods. Among them, compound 1 posse...... hiện toàn bộ
α-Pyrone Derivatives from a Streptomyces Strain Resensitize Tamoxifen Resistance in Breast Cancer CellsNatural Products and Bioprospecting - Tập 7 - Trang 329-334 - 2017

Tamoxifen resistance (TamR) is the underlying cause of treatment failure in many breast cancer patients receiving tamoxifen. In order to look for noncytotoxic natural products with the ability to reverse TamR, an extract from strain Streptomyces sp. KIB-H0495 was detected to be active. Subsequent large scale fermentation and isolation led to the isolation of four α-pyrone derivatives including two...... hiện toàn bộ
Untargeted metabolomics analysis of four date palm (Phoenix dactylifera L.) cultivars using MS and NMRNatural Products and Bioprospecting - Tập 13 - Trang 1-19 - 2023

Since ancient times, the inhabitants of dry areas have depended on the date palm (Phoenix dactylifera L.) as a staple food and means of economic security. For example, dates have been a staple diet for the inhabitants of the Arabian Peninsula and Sahara Desert in North Africa for millennia and the local culture is rich in knowledge and experience with the benefits of dates, suggesting that dates c...... hiện toàn bộ
Bioassay-guided isolation of cytotoxic constituents from the flowers of Aquilaria sinensisNatural Products and Bioprospecting - Tập 12 - Trang 1-9 - 2022
Jun Yang, Dong-Bao Hu, Meng-Yuan Xia, Ji-Feng Luo, Xing-Yu Li, Yue-Hu Wang
Bioassay-guided fractionation of the EtOH extract from the flowers of Aquilaria sinensis (Lour.) Spreng. (Thymelaeaceae) led to the isolation of a new cucurbitane-type triterpenoid, aquilarolide A (1), along with five known compounds (2–6). The structure of 1 was elucidated by extensive 1D and 2D nuclear magnetic resonance (NMR) experiments and mass spectrometry (MS) data and theoretical calculati...... hiện toàn bộ
