| 摘 要： | 食物中添加绿茶提取物或其含有儿茶素的组分显著地增加了喂养高胆固醇食物3周的大白鼠血液和肝脏微粒体磷脂酰胆碱中的亚油酸比例。喂养不含胆固醇的食物时，儿茶素改变了肝脏微粒体磷脂种类的组成，也增加了其中磷脂酰胆碱中的亚油酸比例。这些结果提示儿茶素能够影响脂肪酸以及磷脂的代谢。

| Abstract: | Dietary supplementation with a green tea extract or a fraction containing catechins significantly increased the proportion of linoleic acid in plasma and liver microsomal phosphatidylcholine of rats fed a cholesterol-enriched diet. In rats fed a cholesterol-free diet, purified tea catechins was found to cause alteration of liver microsomal phospholipid class composition, in addition to increase in linoleic acid. The results indicate that tea catechins can affect the metabolism of fatty acid and phospholipid. |
