Section E Quality and Post-harvest Processing Effects of the Oil Extracted From Tartary Buckwheat Bran on Blood Fat and Lipid Peroxidation in Hyperlipemia Rats

Abstract: Objective: To study the effect of the oil extracted from Tartary buckwheat bran on hyperlipemia rats in blood fat and antioxidation. Method: 60 seven week old Wistar rats were randomly divided into six groups according to their body weights; all the groups but the control group fed with normal feed were fed with high-fat feed to induce hyperlipemia in the rats and the dosages of the oil extracted from Tartary buckwheat bran administered with the feed were 0.2, O.5and Ig/kg; 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 mLlkg 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 the oil extracted from Tartary buckwheat bran administered at different dosages and the groups fed with high fat feed indicated that the oil extracted from Tartary buckwheat bran could extremely significantly reduce serum TG contents and liver MDA contents at different dosages(P<O.Ol) and performed best in blood fat reduction and antioxidation at the medium dosage of 0.5g1kg, reducing serum TC content and MDA and liver TG significantly (P<0.05) and liver TC extremely significantly (P<O.OI). Conclusion: The oil extracted from Tartary buckwheat bran had significant effects in blood and liver fat reduction and anti-oxidation. And proper attention should be paid to its effects in fat reduction
