ACCION FARMACOLOGICA= Pharmacological action: Diurética.  

COMPOSICIÓN QUÍMICA= Chemical composition: Investigation of aerial parts of Margyricarpus setosus afforded three new aryl glycosides, beta-hydroxy-phenylethyl-O-alpha-L-rhamnopyranosyl (1-->6)-beta-D-glucopyranoside, benzyl-O-alpha-L-rhamnopyranosyl (1-->6)-beta-D-glucopyranoside, 4-methoxybenzyl-O-alpha-L-rhamnopyranosyl (1-->6)-alpha-D-glucopyranoside, and three new triterpene glycosides, tormentic acid 3beta-O-beta-D-quinovopyranoside, tormentic acid 3beta-O-beta-D-fucopyranoside and tormentic acid 3betaO-alpha-L-rhamnopyranoside. Twelve known compounds were also found, among them beta-hydroxy-3`,4`-dimethoxyphenylethyl glucoside and beta-hydroxy-3`,4`-dimethoxyphenylethyl rutinoside, which were obtained previously by partial synthesis, were isolated for the first time from a natural source. The structures of the new compounds were elucidated on the basis of chemical and spectral data. Copyright © 1996 Elsevier Science Ltd. All rights reserved.
