苦丁茶降血脂的实验及临床研究

[目的]探讨苦丁茶叶的降血脂作用。[方法]用苦丁茶叶水煎浓缩后加乙醇沉淀处理．选取sD大鼠，随机分为4组，分别灌以蒸馏水、50％醇溶苦丁茶、50％醇不溶苦丁茶、多烯康，观察三酰甘油(TG)的变化；另选取高脂血症病人28例，每日服用苦丁茶，1个疗程后测定血脂。[结果]苦丁茶醇溶及醇不溶液及多烯康能明显地降低大鼠血TG；28例病人服用苦丁茶后，降血脂有效率达78．57％。[结论]实验和临床证明服用苦丁茶能有效地降低血脂。

Experiment and clinical study on broadleaf holly leaf to lower down blood lipids level

Objective: to probe into the effect of broadleaf holly leaf on lowering down blood lipids level. Method: broadleaf holly leaf was concentrated by boiling, then add alcohol to precipitate it. SD rats were selected and divided into four groups, and were given distilled water, 50% alcohol-soluble broadleaf holly leaf, 50% alcohol-insoluble broadleaf holly leaf and Max EPA respectively. Subsequently, triglyceride (TG) levels of all the experimental rats were observed. A total of 28 hyperlipidemia patients were selected and given broadleaf holly leaf drinking everyday and blood lipids level was detected after a course of treatment. Result: the TG level of rats can be lowered by either alcohol-soluble, alcohol-insoluble broadleaf holly leaf or Max EPA. And the effective rate of lowering blood lipid accounted for 78.57% in 28 patients after taken broadleaf holly leaf. Conclusion: it can conclude from experiment and clinical test that broadleaf holly leaf has some effectiveness on lowering blood lipid.
