摘要：Lipids extracted from tsao-ko were separated into three fractions with silica gel column chromatography and fed to mice (3 mo old) for 90 d to clarify their inhibitory activity on digestive enzyme activity. The diets contained the following: control—no tsao-ko, 0.05% total lipid of tsao-ko (TL), 0.0109% chloroform fraction (CF), 0.0245% acetone fraction (AF), or 0.00365% methanol fraction (MeF). Although CF and AF slightly inhibited the activities of α-glucosidase, α-amylase, and lipase, intakes of these fractions had little influence on plasma and liver lipid concentrations when compared with the control diet. MeF did not inhibit α-glucosidase but had DPPH radical scavenging activity and the mice fed this fraction had the most marked reduction in plasma glucose and TBARS concentrations compared with the other diet groups. These results suggest that the fat-soluble polar components of tsao-ko contain an active component that might be associated with decreased plasma glucose and TBARS concentrations in mice.
