    Study on chemical constituents of Herba Siegesbeckiae.[Reference: WebLink]
    To study the chemical constituents in the ethyl acetate fraction of Herba Siegesbeckiae.
    METHODS AND RESULTS:
    Compounds were isolated and purified by silica gel columns and MPLC, and their structures were identified by the physicochemical properties and spectral analysis. 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 (ent-16beta,17-Dihydroxy-19-kauranoic acid,5), ent-16αH-17- hydroxy-19-kauranoic acid (6) and stigmasterol (7).
    CONCLUSIONS:
    Compound 1 is the new compound.
