Abstract:
Thirteen compounds were isolated and purified from the ethanol extract of Clerodendrum trichotomum Thunb. by various chromatographic methods. Their structures were identified as friedelin(1), betulinic acid(2), taraxerol(3), platanic acid(4), acacetin(5), 5, 7-dihydroxy 3′, 4′-dimethoxyflavone(6), β-sitosterol(7), stigmasterol(8), daucosterol(9), stigmasterol-3-O-glucopyranoside(10), isovanillin(11), dibutyl phthalate(12)and syringaldehyde(13). Compounds 4, 6, 11- 13 were isolated from genus Clerodendrum Linn. for the first time. Compounds 4, 6, 10- 13 were isolated from Clerodendrum trichotomum Thunb. for the first time.
