摘要

摘要: 通过高效液相色谱法（HPLC）测定不同红茶中γ-氨基丁酸（γ-aminobutyric acid,GABA）、L-茶氨酸和L-谷氨酸的含量,并通过小鼠自主活动测试仪比较不同主要氨基酸含量的红茶水提物对小鼠自主活动的影响。结果表明,不同红茶中GABA、L-茶氨酸和L-谷氨酸含量差别均较大,并且L-茶氨酸含量普遍高于GABA、L-谷氨酸含量。其中,GABA含量以高黎贡山为最高,汉水韵红茶次之,紫鹃红最低;L-茶氨酸和L-谷氨酸含量均以八仙红茶为最高,汉水韵红茶次之,印度大吉岭红茶最低。此外,动物实验结果显示,与主要氨基酸含量较低红茶组相比,主要氨基酸含量较高红茶组小鼠的自主活动次数显著减少（p<0.05）。以上结果提示,主要氨基酸含量较高的红茶对小鼠具有明显的镇静作用。

Abstract: The γ-aminobutyric acid ( GABA) , L-theanine and L-glutamic acid contents in different black tea were determined by high-performance liquid chromatography ( HPLC) , and the effects of black tea water extract at different main amino acids contents on the locomotor activity of mice were monitored using a mouse activity monitor system. The results showed that the contents of GABA, L-theanine and L-glutamic acid were different in the different black tea samples, and the content of L-theanine was higher than that of GABA and L-glutamic acid. Among them, the GABA content in Gaoligongshan was the highest, followed by Haishuiyun black tea, and Zijuanhong was the lowest; the L-theanine and L-glutamic acid contents in Baxian black tea were the highest, followed by Haishuiyun black tea, and India Darjeeling black tea were the lowest.Additionally, the result of animal experiment showed that the locomotor activity level in the black tea with higher main amino acids content group was significantly decreased compared with that in the black tea with lower main amino acids content group ( p < 0.05) .The above results suggested that black tea with a high content of main amino acids had a significant sedative effect on mice.
