亚麻籽对血脂的调节作用

Effects of Flaxseed on Blood Lipids in Rats

以国产亚麻籽 (低、中、高 3种剂量 )喂饲Wistar大鼠 32d,观察其对大鼠血清总胆固醇 (TC)、三酰甘油(TG)、高密度脂蛋白胆固醇 (HDL C)、高密度脂蛋白胆固醇与总胆固醇的比值 (HDL C/TC)、低密度脂蛋白胆固醇(LDL C)、载脂蛋白 B(Apo B)及动脉硬化指标 (AI)的影响 ,并与高脂饲料组和基础饲料组进行比较。结果 ,亚麻籽粉低、中、高剂量组的TC和LDL C均显著低于高脂饲料组 (P <0 .0 5) ;中、高剂量组的TG、Apo B及AI显著低于高脂饲料组 (P <0 .0 5) ,HDL C/TC、AI显著高于高脂饲料组 (P <0 .0 5) ,而HDL C则与高脂饲料组无显著差异 (P >0 .0 5)。提示富含α 亚麻酸的国产亚麻籽具有良好的降低血脂的作用 。

The experimemt observed effect of flaxseed on Wistar rats′ serum triglyceride(TG), total cholesterol(TC), high density lipoprotein cholesterol(HDL C), low density lipoprotein cholesterol(LDL C), Apo B and atherosclerosis index(AI). The rats were divided into a lard group, three flaxseed groups(low, middle and high level) and a basal diet group. Thirty two days later, significant decrease in serum TC and LDL C were found in the flaxseed groups(low, middle and high level) as compared with the lard group( P < 0.05 ), significant decrease in serum TG and significant increase in serum Apo B, HDL C/TC and AI were found in the flaxseed groups(middle and high level) as compared with the lard group( P < 0.05 ), but there was no difference in HDL C between flaxseed group and lard group( P > 0.05 ). The experiment indicates that flaxseed rich in α linolenic acid can be used to prevent and lower blood lipid, and deserves further study and development.
