ABSTRACT
Objective: To study the effects of the total flavonoids of tartary buckwheat germ (TFTBG) on serum lipid and antioxidation in hypercholesterolemic rats. Method: According to body weight,60 Wistar rats were divided randomly into 6 groups: normal control group (NC), high-fat control group (HFC), Jiaogulan positive control group (JPC, Gynostemma pantaphyllum total glucoside tablet 0.032g/kg bw),TFTBG 1.0,0.5and TFTBG 0.2 g/kg bw (HD,MD,LD) group. Except NC group, all other groups were fed high-fat diet for hyperlipidemia model. NC group and HFC group were given distilled water 10 ml/kg bw. Water and TFTBG were given by gavage once a day for 6 w respectively. Serum TG, TC HDL-C, LDL-C, apoA1, apoB, SOD, GSH-Px and MDA were determined. Results: Compared with HFC group, serum TG ,TC were lowered significantly(P
ABSTRACT
Objective: To analyse the composition and content of the fatty acid and unsaponifiable matters in both tartary buckwheat seed oil and buckwheat seed oil. Methods: Fatty acids were obtained by the methods of KOH-EtOH(95%) saponification and treatment of inorganic acid. They were analyzed and determined by gas chromatography and GC/MS chromatography respectively. Results: 4-5 kinds of fatty acid were determined in both oils, and the content of unsaturated fatty acids in tatary buckwheat oil was 83.2% ( oleic acid 47.1%, linoleic acid 36.1%), buckwheat oil was 81.8% ( oleic acid 35.8% , linoleic acid 40.2% and linolenic acid 5.8%). The content of unsaponifiable matters in tartary buckwheat seed oil was 6.56%(?-sitosterol 54.37%), and in buckwheat seed oil was 21.90%(?-sitosterol 57.29%,?-tocopherol 1.41%). Conclusion: Both buckwheat oils were functional vegetable oils.
