Abstract
A new prenylated benzofuran derivative, named flemiphilippinone A, was isolated together with ten known flavonoids from the roots of Flemingia philippinensis. Flemiphilippinone A was identified as (2S,3aS)-5-(1-hydroxy-3-(4-methoxyphenyl)- propylidene)-2-(2-hydroxypropan-2-yl)-3a,7-bis(3-methylbut-2-en-1-yl)tetrahydrobenzo- furan-4,6(2H,5H)-dione, and its structure was established by a combination of HR EIMS, 1H-NMR, 13C-NMR, HMQC, HMBC and NOESY spectra data.Keywords
