Section E Quality and Post-harvest Processing Effects of Total Flavonoids Extracted From Tartary Buckwheat Bran on Blood Fat and Antioxidation in Hyperlipemia Rats

Abstract: Objective: To study the effect of total tlavonoids of Tartary buckwheat bran on hyperlipemia rats in bloodfat reduction andantioxidation. Method: ro sevenweekold WlStar ratsweredivided intosix groups according to theirlxxlyweights; all the groups butthecontrolgroup fed withnormalfeed werefed withhigh-fat feed to induce hyperlipemia in the rats and thedosages of total tlavonoids of Tartary buckwheatbran administered with the feed were 0.2, 0.5and 191kg; the groups fed with both high-fat feed and Gynostemma pantaphyllum total glucoside tablet at 0.032g1kg was the positive control group; In the group fed with normal feed and the groups fed with high-fat feed distilled water was charged into the stomachs of the rats at 10 mUkg every day for six weeks and then blood fat, liver fat and antioxidation-related parameters of the rats were measured. Results: the comparison of the groups with total flavonoids of Tartary buckwheat bran administered at different dosages and the groups fed with high fat feed indicated that total tlavonoids of Tartary buckwheatbrancould effectively reduce serumro (P<0.01) and TC (P<O.Ol) at different dosages; On one hand it reduced liver TC and TG separately by36.4 % (P<O.Ol) and 73.9 % (P<O.Ol) ( P<0.01 at the dosages of 0.2 and 0.5 g/kg-d and P<0.05 at the dosage of 1.0 g/kg-d) presenting remarkable effects in serum triglyceride reduction, anti-arteriosclerosis and serum-lipid oxidation resistance and on the othe
