Abstract
OBJECTIVE To study the chemical constituents in the ethyl acetate fraction of Herba Siegesbeckiae.METHODS Compounds were isolated and purified by silica gel columns and MPLC, and their structures were identified by the physicochemical properties and spectral analysis. RESULTS Seven compounds were isolated and elucidated as 3′, 5′,β-trihydroxy-3,4,4′,α-tetramethoxy-chalcone(1),kirenol(2),darutigenol(3),siegesbeckic acid(4),ent-16β,17-dihydroxy-19-kauranoic acid(5),ent-16αH-17-hydroxy-19-kauranoic acid(6) and stigmasterol(7).CONCLUSION Compound 1 is the new compound.
