摘　　要：茶氨酸是茶科植物中特有的酰胺类氨基酸,通常在绿茶内含量较高,其理化性质、保健作用、分子作用机理等方面被广泛研究。近年来,大量的研究发现,茶氨酸具有非常好的保健作用与医药效果,比如茶氨酸可以减轻脑组织以及肝组织的损伤,提高免疫细胞的免疫能力,降低神经细胞的凋亡率,抑制肿瘤的形成,抑制癌细胞增殖等。文章主要综述了茶氨酸的吸收与代谢、组织损伤的保护作用及其在免疫细胞、神经细胞和癌细胞的作用机制,以期为茶氨酸在细胞、组织、机体等方面的深入研究与综合应用提供科学依据。Theanine is a peculiar kind of amide amino acids in tea plants, especially higher in green tea. It has been extensively studied in physical and chemical properties, health function and molecular mechanism. In recent years, a large number of researches have found that theanine has great health care function and medicinal effect,for example, theanine can relieve tissue（brain and liver） damage, improve the immune ability of immune cells,reduce the apoptosis rate of nerve cells, inhibit the formation of tumor and proliferation cancer cells. This research summarized the absorption and metabolism, protective effect of tissue damage and functional mechanism on immune cells, nerve cells and cancer cells of theanine, expecting to provide scientific basis for the intensive research and integrated application of theanine in cells, tissues and organism.
