Abstract
Two new sulfated triterpenoid saponins, zygophylosides Q (1) and R (2), have been isolated from the barks of Zygophyllum fabago L. Their structures were elucidated as 3beta,24,28,30-tetrahydro-urs-20-ene-24-O-sulphonyl-3-O-[beta-D-glucopyranosyl]-30-O-beta-D-glucopyranoside and 3beta,24,28,30-tetrahydro-urs-20-ene-24-O-sulphonyl-3-O-[beta-D-xylopyranosyl]-30-O-beta-D-glucopyranoside, respectively, by spectral and chemical evidence.
