New Phenolic Glycosides from Physalis angulata

Two new phenolic glycosides from Viscum articulatum.

Two new phenolic glycosides, 1-O-benzyl-[5-O-benzoyl-beta-D-apiofuranosyl (1-->2)]-beta-D-glucopyranoside (1), and 4;-hydroxy-7,3;-dimethoxyflavan-5-O- beta-D-gluco-pyranoside (2), together with nine known flavanones 3 - 11, have been isolated from the dried whole plants of Viscum articulatum.Their structures were identified by extensive spectral analysis, especially 2D NMR techniques. Compound...

New Phenolic Glycosides from Phyllanthus cochinchinensis

A investigação química das plantas Phyllanthus cochinchinensis (Euphorbiaceae) levou ao isolamento de três novos glicosídeos fenólicos, filantuosídeos A-C, juntamente com 12 compostos conhecidos. Suas estruturas foram determinadas com base em extensivas análises espectroscópicas e métodos químicos. Dentre eles, filantuosídeos A e B são dois glicosídeos fenólicos raros, com um esqueleto C6-C3-C6...

Four new phenolic glycosides from Baoyuan decoction

Four new phenolic glycosides, including two flavonoid glycosides (1 and 2) and two lignan glycosides (3 and 4), were isolated from the traditional Chinese medicine formula, Baoyuan decoction. Their structures were established by detailed analysis of the NMR and HR-ESI-MS spectroscopic data and their absolute configurations were determined by the experimental electronic circular dichroism data a...

Physalis Angulata L . : an Ethanopharmacological Review

Cytotoxic withanolides from Vietnamese ethno-medicinal plant Physalis angulata

Withanolides are known as the main components of Physalis genus with broad biological activities. Using combination of various chromatographic methods, three withanolides were isolated including physagulin J (1), physagulin K (2), and physagulin N (3). Their chemical structures were determined by analysis of NMR spectra, and as well as comparison with reported literature. Compound 1 showed sign...
