Abstract:
Six compounds were isolated from the twigs of Ilex macropoda. Their structures were elucidated as betulinic acid, lupeol, betulone, betulin, erythrodiol and 11-oxo-erythrodiol by physicochemical and spectroscopic analysis. Among them, lupeol, betulone, erythrodiol and 11-oxo-erythrodiol were isolated for the first time from this plant.
