title: Proposed active constituents of Dipladenia martiana.
abstract: 3Beta-O-beta-D-glucopyranosylsitosterol, pomolic acid, ursolic acid, epicatechin, kaempferol, kaempferol-3-O-beta-D-glucopyranoside (astragalin), quercetin-7-O-beta-D-glucopyranoside, quercetin-7-O-beta-D-galactopyranoside and quebrachitol were isolated by chromatographic fractionation of the methanol extract from the aerial parts of Dipladenia martiana (Apocynaceae). The hexane extract yielded lupeol and sitostenone. These compounds are likely to be responsible for the therapeutic effects.
