One new triterpenoid, 3beta, 16beta, 23, 28-tetrahydroxy oleana-11, 13(18)-dien-3-O-beta-D-glucopyranosyl(1 --> 3) [beta-D-glucopyranosyl(1 --> 2)]-beta-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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
