紫苏叶提取物对高脂血症家兔血脂及脂质过氧化的影响

[目的]观察紫苏叶提取物(FPE)对家兔高脂血症的防治作用。[方法]采用高脂饮食,建立家兔高脂血症模型,分别测定正常对照组、高脂模型组、紫苏叶提取物低剂量组(0.17g/kg)、中剂量组(0.5g/kg)、高剂量组(1.5g/kg)血清中TC、TG、LDL-C、HDL-C、MDA含量及SOD的活性。[结果]FPE(0.17g/kg、0.5g/kg、1.5g/kg)组均能显著降低血清中TC、TG、LDL-C、MDA的含量(P<0.01),并能提高血清中HDL-C的含量(P<0.01)和SOD的活性(P<0.05)。[结论]FPE具有一定的调节血脂及抗脂质过氧化的作用。

The Effects of Folium Perillae Extract on Blood Fat and Lipid per Oxidation of Rabbit with Hyperlipemia

[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.
