Methods The chemical constituents were isolated and purified by various column chromatographic methods and preparative HPLC. Their structures were identified by physicochemical properties and spectral analyses. Results Seventeen compounds were isolated from the methanol extract and identified as N-trans-cinnamoyltyramine(1), N-trans-p-coumaroyltyramine(2), N-cis-p-coumaroyltyramine(3), N-transferuloyltyramine(4), N-cis-feruloyltyramine(5), loliolide(6), dehydrovomifoliol(7),(3S, 5R, 8R, 9R)-5, 8-epoxy-6-megastigmene-3, 9-diol(8),(3R, 6R, 7E)-3-hydroxy-4, 7-megastigmadien-9-one(9),(3R)-4-[(2R, 4S)-2-hydroxy-2, 6, 6-trimethylcyclohexylidene]-3-buten-2-oneiol(10), 7-methoxycoumarine(11), imperatorin(12), 7-hydroxy-8-methoxycoumarin(13), 6-hydroxy-7-methoxycoumarin(14), indole-3-aldehyde(15),(-)-medioresinol(16), and daidzein(17).
