Abstract:A phytochemical study of the ethyl acetate extract (EtOAc) of Styrax annamensis leaves resulted in the isolation and determination of six known compounds, including three nor‐neolignans type 2‐phenylbenzofurans egonol (1), egonoic acid (2) and (–)‐machicendiol (3), two lignans styraxin (4) and vladinol D (5), and a triterpenoid pomolic acid (6). The chemical structures of these compounds were determined by NMR spectroscopies, and MS data. This is the first time to isolate these compounds from S. annamensis spe… Show more
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.
