紫苏具有良好的抗氧化作用,但大部分研究只局限于体外实验,有关调节血脂方面的研究则鲜有报道,并且研究主要是集中在紫苏籽油上。对于紫苏叶是否具有抗高脂血症及脂质过氧化方面的研究还未见报道。为此,笔者从已有的理论基础出发.对紫苏叶提取物调节血脂及抗脂质过氧化的方面作用进行研究。
[Objective] The preventive and therapeutic effects of Folium perillae extract (FPE) on hyperlipemia induced by feeding rabbit with high fat forage were observed. [Method] The high fat and cholesterol diet were adopted to create the hyperlipemia model of rabbit. The rabbits were randomly and equally divided into 5 groups which were NC( normal control)group, HLM (high lipid model) group, LFPE, MFPE and HFPE group (low, middle, high dosage of FPE were 0.17 g/kg, 0.5 g/kg and 1.5 g/kg respectively). The contents of TC, TG, LDL-C, HDL-C, MDA and the activity of SOD in serum were detected respectively. [ Result] The three FPE groups could decrease the contents of TC, TG, LDL-C, MDA significantly (P〈0.01) compared with these of HLM group, and the contents of HDL-C (P〈0.01) and the activity of SOD (P〈0.05 ) in serum was increased significantly. [Conclusion] FPE could regulate blood-fat and counteract lipid peroxidation.
