【摘要】 目的:从桂花中分离出三萜类成分,并对其降血脂作用及抗氧化活性进行研究。方法:采用索氏提取法提取桂花,富集三萜类成分,采用灌胃高脂乳剂法建立高脂血症小鼠模型,考察桂花三萜对高脂血症小鼠降血脂作用和抗氧化能力的影响。结果:与高脂模型组相比,三萜类成分给药组血清中TC,TG,LDL-C水平均显著降低,SOD水平显著升高,MDA水平显著下降。结论:桂花三萜类成分具有明显的降血脂和抗氧化活性,其作用机制有待进一步研究。更多还原

【Abstract】 Objective: Triterpenoids component was separation from Osmanthus fragrans,study on hypolipidemic and antioxidant activity of Osmanthus fragrans in vivo. Method: Soxhlet extraction was used to extract,and triterpenoids fraction were colected from the ethyl acetate extract,the hyperlipidemia mice model was established by intragastric administration of high fat emulsion. Investigation of triterpenoids fraction in hyperlipemia mice lipid levels and antioxidant effects. Result: Compared with hyperlipidemia model group,the content of TC, TG,LDL-C of serum in the triterpenoids groups were significantly decreased,the levels of SOD were significantly increased and the levels of MDA were significantly decreased. Conclusion: Triterpenoids fraction of O. fragrans has effection of hypolipidemic and antioxidantion activity,the exact lipid-lowering effect needs further investigation.更多还原
