Chemical constituents of Poria cocos

China Journal of Chinese Materia Medica, 2014
The chemical constituents of Poria cocos were studied by means of silica gel, ODS column chromatography, Sephadex LH-20 and preparative HPLC. Thirteen compounds were isolated from this plant. By analysis of the ESI-MS and NMR data, the structures of these compounds were determined as tumulosic acid (1), dehydrotumulosic acid (2), 3beta, 5alpha ...

Triterpenes of Poria cocos

Phytochemistry, 1993
Abstract Four lanostane triterpenes and four novel 3,4- seco -lanostane triterpenes were isolated from the surface layer of Poria cocos . 3β-Hydroxylanosta-7,9(11),24-trien-21-oic acid, trametenolic acid, dehydroeburicoic acid and eburicoic acid were isolated by HPLC after treatment with N -chloromethylphthalimide. Four novel 3,4- seco -lanostanes:

Anti-Emetic Principles ofPoria cocos

Planta Medica, 1995
The triterpenes isolated from P. cocos and their derivatives were examined for anti-emetic activity. Some of these triterpenes inhibited emetic action induced by oral administration of copper sulfate pentahydrate to leopard frog. The triterpenes having an exomethylene group at C-24 showed anti-emetic activity to frogs.

A genotoxicity assessment approach for botanical materials demonstrated with Poria cocos

Food and Chemical Toxicology, 2021
Safety assessment of botanical materials often reveals genotoxicity data gaps. However, there are no harmonized regulatory genotoxicity testing approaches for botanical materials. Furthermore, literature genotoxicity testing reports often lack clear definition of the botanical materials (genus species, plant part, etc.) and/or analytical ...

Diuretic activity of some fractions of the epidermis of Poria cocos

Journal of Ethnopharmacology, 2013
Poria cocos Wolf (Polyporaceae) is a well-known medicinal fungus, the epidermis ("Fu-Ling-Pi" in Chinese) of the sclerotia is used as a diuretic for treating oedema and promoting the diuretic process. In this paper we report on the diuretic activity in rats of petroleum ether, ethyl acetate, n-butanol and the remaining fractions of the ethanol extract ...
