Deskripsi
Chemical investigation of Arrabidaea samydoides resulted in the isolation of the flavone chrysin; five triterpenes: lupeol, ursolic acid, 3b,16a-dihydroxy-urs-12-ene, uvaol, and erythrodiol; and two sterols: sitosterol and stigmasterol. The structures of these compounds were established by spectroscopic analysis. This paper deal with the first phytochemical study of Arrabidaea samydoides.
