摘要
Abstract
Turnip（Brassica rapa L.）was a magic plant in high altitudes,it was used as a kind of food with a long history for Tibetan and yak.We used Tibetan turnip as material,assay the amino acid,mineral element and Vitamins contents in it.The anti-hypoxic effect of turnip frozen-dry powder on ICR mice was studied.To investigate the extension of the mice hypoxia tolerance,three doses（0.5,1.0,2.0g/kg·bw·d）was set.And Rhodiola rosea was taken as a positive control and distilled water was as a blank control,the survival time of mice in hypoxia under ordinary pressure was the evaluating indicator.Weigh the mice liver and assay protein contents and SOD activity.The research indicated that high dose at 2.0g/kg·bw·d of turnip powder and positive control showed a significant extension effect on the mice hypoxia tolerance;mid-and high-doses as well as positive control had a significant promotion on liver SOD activity;and the body weight index and hepatopancreas somatic indices of all tested mice were not of obvious difference.It indicated that Tibetan turnip could improve mice hypoxia tolerance and the antioxidation capacity in vivo of mice.关键词
