黄花倒水莲总皂苷的调脂作用

Study on the Lipid Regulating Effects of Total Saponins from Polygala aureocauda Dunn

  • 摘要: 目的:利用大鼠食饵性高脂血症模型研究黄花倒水莲总皂苷(PTS)调脂作用。方法:预防性给药时,连续给予高脂饲料21d后形成高脂模型,给高脂饲料同时给予黄花倒水莲总皂苷,21d后改用普通饲料,继续给药14d,分别于第21天和第35天测定血清中TC、TG、MDA含量。治疗性给药时,连续给予SD大鼠高脂饲料,21d后形成高脂模型,停止造模,给予普通饲料并给予PTS,给药14d后测定血清中TC、TG、HDL-C、LDL-C、MDA含量和SOD活性。结果:预防性给药时大鼠造模21d后TC、TG和MDA含量升高,PTS高剂量能降低血清中TC、TG和MDA含量;继续给药14d后,PTS高剂量组能明显降低血清中TC、TG和MDA含量。在治疗性给药中,高剂量组能显著降低血清TC、TG、LDL-C和MDA含量并显著升高HDL-C含量和SOD活性。结论:高脂饲料喂养21d即可形成高脂模型;黄花倒水莲总皂苷对大鼠血清TC、TG及MDA含量均有降低作用并呈剂量相关性。黄花倒水莲总皂苷具有调节血脂的作用和一定的抗氧化作用。
