Abstract

Two new triterpenoid saponins, zygophylosides O (1) and P (2), have been isolated from the barks of Zygophyllum fabago L. Their structures were elucidated as 3β-[(2-O-sulfo-β-D-xylopyranosyl)oxy]urs-12-ene-27,28-dioic acid and 3β-[(2-O-sulfo-β-D-xylopyranosyl)oxy]urs-12-ene-27,28-dioic acid 28-β-D-glucopyranoside, respectively, by spectral and chemical evidence. Compound 1 showed weaker Nitric Oxide (NO) inhibitory activity.
