Take 10 kg of Cistanche salsa (CAMey) G.Beck from China’s Inner Mongolia Autonomous Region. After fine cutting, soak 3 times with methanol and suspend the methanol extract in water. Extract with ethyl acetate and n-butanol in sequence to obtain Butanol extract 96 grams. The resulting n-butanol extract was subjected to silica gel column chromatography and eluted with chloroform-methanol (10:1→3:1). The fraction eluted with chloroform-methanol (5:1) was repeatedly purified to give 200 mg of Compound I and 230 mg of IV. Another water
