摘要/Abstract

摘要： 研究了采用碱法从茶叶中提取非水溶性茶叶蛋白的工艺,茶叶蛋白提取率达61.1%。通过调节提取液pH值的方法制备粗蛋白,粗蛋白纯度为54.45%;以高血脂症大鼠为模型,研究了非水溶性茶叶蛋白的降血脂作用。结果表明：非水溶性茶叶蛋白能明显降低高血脂症大鼠血清TC、TG、LDL-C、AI和R-CHR指标（P<0.05）,对HDL-C有一定的调节作用;证明非水溶性茶叶蛋白有明显的降血脂效果,对抗动脉粥样硬化及冠心病可能有一定的预防作用。

Abstract: Alkali extraction technology of water insoluble protein from tea was studied. The extracting rate of tea protein was around 61.1%. The crude tea protein was prepared by adjusting pH of the extract and its purity was 54.45%.The effects of water insoluble tea protein on decreasing blood lipids were studied on the hyperlipidemia rats. Results showed that the protein had significant effects on decreasing TC、TG、LDL-C、AI and R-CHR in the hyperlipidemia rats(p<0.05). It could also modulate the HDL-C indexes. The results confirmed that the water insoluble tea protein had remarkable effects on decreasing the blood lipid of hyperlipidemia and possibly is preventing atherosclerosis and coronary heart disease.

Key words: Water insoluble tea protein, Hyperlipidemia, Lipid-decreasing
