Ethanol extract of Alpiniae Katsumadaii semen inhibited potently cholesterol esterase activity in vitro. Chloroform fraction of ethanol extract showed the stronger inhibitory effect than other solvent fractions-ethylacetate fraction, butanol fraction, and aqueous fraction. The chloroform fraction of Alpiniae katsumadaii semen were wtudied as a candidator of plasma cholesterol lowering material in high cholesterol-fed rats. In high cholesterol-fed rats, the diet with chloroform fraction of 100 mg/kg and 150 mg/kg lowered not only plasma neutral lipids contents 25.9% and 26.5% but also plasma total cholesterol level 11.8% and 20.8%, respectively. Plasma HDL-cholesterol level and Atherogenic Index(AI) in Alpiniae chloroform fraction-fed rats were recovered as those level of normal rats.
