title: New pomolic acid triterpene glycosides from Zygophyllum eichwaldii.
abstract: Two new bisdesmosidic triterpenoid saponins, 3-O-[alpha-L-2-O-sulphonylarabinopyranosyl]-pomolic acid-28-O-[beta-D-glucopyranosyl] ester (zygoeichwaloside H) and 3-O-[beta-D-2-O-sulphonylglucopyranosyl]-pomolic acid-28-O-[beta-D-glucopyranosyl] ester (zygoeichwaloside K) were isolated from the roots of Zygophyllum eichwaldii. The structures were established primarily on the basis of NMR spectroscopy and chemical transformations.
