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
New seco-anthraquinone glucoside from the roots of Rumex crispus
Natural Products and Bioprospecting - Tập 12 - Trang 1-9 - 2022
Yong-Xiang Li, Na Li, Jing-Juan Li, Man Zhang, Hong-Tao Zhu, Dong Wang, Ying-Jun Zhang
A new seco-anthraquinone, crispuside A (1), and three new 3,4-dihydronaphthalen-1(2H)-ones, napthalenones A-C (2–4), were isolated from the roots of Rumex crispus L., along with 10 known anthraquinones (6–14) and naphthalenone (5). Their structures were fully determined by extensive spectroscopic analyses, including ECD, and X-ray crystallography in case of compound 5, whose absolute configuration...... hiện toàn bộ

Ypsiyunnosides A–E, Five New Cholestanol Glycosides from Ypsilandra yunnanensis
Natural 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 Cells
Natural Products and Bioprospecting - Tập 7 - Trang 329-334 - 2017
Rui-Min Yang, Xiu-Lei Zhang, Li Wang, Jian-Ping Huang, Jing Yang, Yi-Jun Yan, Jian-Ying Luo, Xiang-Ting Wang, Sheng-Xiong Huang
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 NMR
Natural Products and Bioprospecting - Tập 13 - Trang 1-19 - 2023
Shuruq Alsuhaymi, Upendra Singh, Inas Al-Younis, Najeh M. Kharbatia, Ali Haneef, Kousik Chandra, Manel Dhahri, Mohammed A. Assiri, Abdul-Hamid Emwas, Mariusz Jaremko
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 sinensis
Natural 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
