The ethanol residue was suspended in water and successively extracted with petroleum ether, dichloromethane, ethyl acetate and n-butanol to yield 73.80 g of petroleum ether extract (Hylo A); 10.28 g of DCM extract (Hylo B); 3.26 g of ethyl acetate extract (Hylo C); 12.42 g of n-butanol extract (Hylo D) and 50.60 g of the residual (Hylo E), The precipitate (Hylo T) was separated by column chromatography to obtain 3 sterols (chalinasterol, daucosterol and ergost 4, 24 (28) dien-3-one) and p-hydroxybenzoic acid.
