New triterpenoid from Stellaria media (L.) Cyr

Abstract

One new triterpenoid, 3β, 16β, 23, 28-tetrahydroxy oleana-11, 13(18)-dien-3-O-β-D-glucopyranosyl(1 → 3) [β-D-glucopyranosyl(1 → 2)]-β-D-fucopyranoside (1), together with two known flavonoids, were isolated from Stellaria media (L.) Cyr. The structure elucidation of the new compound was primarily based on HREIMS, EIMS, UV, IR, 1D- and 2D-NMR analyses, including COSY, HMQC and HMBC correlations.
