A new lignan, (−)‐secoisolariciresin‐9‐yl 6‐O‐p‐coumaroyl‐β‐D‐glucopyranoside (1), named hypenol, along with eleven known compounds, i.e., hyperin, rosmarinic acid, methyl rosmarinate, a mixture of the triterpenes betulinic acid, ursolic acid, and oleanolic acid, glycosylated β‐sitosterol, a mixture of the flavanones sakuranetin and isosakuranetin, hinokinin, and β‐peltatin A dimethyl ether were isolated from the EtOH extract of the leaves of Hypenia salzmannii (Benth.) Harley. The structures of the compounds were elucidated based on the analysis of spectral data, including MS, 1D‐ and 2D‐NMR, and comparison with data in the literature.
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.
