Antibacterial and Anti-Inflammatory Activities of Physalis Alkekengi var. franchetii and Its Main Constituents
This study was designed to determine whether the 50% EtOH fraction from AB-8 macroporous resin fractionation of a 70% EtOH extract of P. Alkekengi (50-EFP) has antibacterial and/or anti-inflammatory activity both in vivo and in vitro and to investigate the mechanism of 50-EFP anti-inflammatory activity. Additionally, this study sought to define the chemical composition of 50-EFP. Results indica...
متن کاملTwo new megastigmane glycosides, physanosides A and B, from Physalis alkekengi L. var. franchetii, and their effect on NO release in macrophages.
Two new megastigmane glycosides, physanosides A and B (1 and 2, resp.), were isolated from Physalis alkekengi L. var. franchetii, together with four known compounds (6S,9R)-roseoside (3), (6S,9S)-roseoside (4), (6R,9S)-3-oxo-alpha-ionol beta-D-glucopyranoside (5), and citroside A (6). Their structures were elucidated on the basis of physicochemical evidence, in-depth NMR spectroscopic analysis,...
متن کاملWithanolides from Physalis hispida.
Nine new withanolides (1-9), withahisolides A-I, were isolated along with nine known compounds (10-18) from the aerial parts of Physalis hispida. The structures of 1-9 were elucidated through a variety of spectroscopic techniques, while the structures of 1 and 2 were confirmed by X-ray crystallographic analysis. Compounds 1-3 are the first withanolides with nonaromatic six-membered ring D moiet...
متن کاملWithanolides from Physalis coztomatl.
Six withanolides (1-6), as well as two known withanolides (physachenolide D 7 and withanoside VI 8), were isolated from the aerial parts of Physalis coztomatl (Solanaceae). Structural elucidations of 1-6 were achieved through 2D NMR and other spectroscopic techniques, while the structure of 1 was confirmed by X-ray crystallographic analysis. In addition, the stereochemical orientation of the 17...
متن کاملCytotoxic 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...
