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.

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 3beta-[(2-O-sulfo-beta-D-xylopyranosyl)oxy]urs-12-ene-27,28-dioic acid and 3beta-[(2-O-sulfo-beta-D-xylopyranosyl)oxy]urs-12-ene-27,28-dioic acid 28-beta-D-glucopyranoside, respectively, by spectral and chemical evidence. Compound 1 showed weaker Nitric Oxide (NO) inhibitory activity.

From the bark of Zygophyllum fabago L., a new 27-nor-triterpenoid glycoside, 3-O-beta-D-glucopyranosyl-pyrocincholate (1), together with five known compounds, 3-O-6-deoxy-beta-D-glucopyranosyl-pyrocincholate (2), quinovic acid (3), 3-O-6-deoxy-beta-D-glucopyranosyl-quinovic acid (4), 3-O-beta-D-glucopyranosyl- quinovic acid (5) and 3-O-6-deoxy-beta-D-glucopyranosyl-cincholic acid (6), were isolated and their structures elucidated on the basis of spectroscopic data. Compounds 1, 2 and 3 showed some anti-tumour activities by MTT assay.
