Two new saponins from Zygophyllum atriplicoides

Chem Pharm Bull (Tokyo). 2005 Sep;53(9):1126-30. doi: 10.1248/cpb.53.1126.

Abstract

Phytochemicals investigation of the whole plant of Zygophyllum atriplicoides resulted in the isolation of two new triterpenoidal saponins together with a known compound. The structure of the new compounds atriplicosaponin A (1) and atriplicosaponin B (2) were established as 3-O-[alpha-D-glucopyranosyl-(1-->2)-beta-D-xylopyranosyl]-hederagenin and 27 alpha-hydroxyurs-12-ene-3-O-[beta-D-glucopyranosyl(1-->4)(2-O-sulpho)-beta-D-quinovopyranoside] and known compound was identified as 3-O-[beta-D-glucopyranosyl]-beta-sitosterol. The structure elucidations of the compounds were based primarily on 1D and 2D-NMR analysis, including COSY, HMBC and HMQC correlations.
