Abstract

Fuzhuan Tea was extracted by chloroform, ethyl acetate, 1-butanol in turn. The effect of Fuzhuan Tea on the activities of metabolize enzyme was investigated. The results showed that different fractions of Fuzhuan Tea had different effects on pancreatic lipase activity. The sample extracted by chloroform could restrain pancreatic lipase a little and the relative activity was 0.82. The water extracts, the sample extracted by ethyl acetate and 1-butanol showed obvious activation, that of the sample extracted by 1-butanol was the most active. The multiple was 2.54. All fractions of Fuzhuan Tea were active to α-amylase, among them, the sample extracted by ethyl acetate was the most active. The relative activiy was 4.09. The water extracts was the second one and its relative activity was 2.99. That of the layer of water sample was not obvious. The sample extracted by chloroform could restrain α-amylase a little and the relative activity was 0.88. The samples separated from the sample extracted by ethyl acetate and the sample extracted by 1-butanol were active to α-amylase and pancreatic lipase respectively.
