以川西茶区５个主栽品种为供试材料，对春梢和秋梢进行氨基酸组分测定。结果表明：在川西的地域条件下，主栽品种的氨基酸组成和含量具有一定特征。５个品种的游离氨基酸总量均较高；品种间各种氨基酸的含量差异较小；从氨基酸组成来看，茶氨酸的含量水平居中等偏低，但谷氨酸等其它主要氨基酸的含量较高；新梢中还富含赖氨酸等人体必需的氨基酸；各种氨基酸的季节变化规律明显，总体趋势是春高秋低 Five main cultivars in the tea area of ​​western Sichuan were used as materials to test the amino acid composition of spring shoots and autumn shoots. The results showed that the amino acid composition and content of main cultivars had certain characteristics under the regional conditions in western Sichuan. The total amount of free amino acids in the five cultivars were higher than those in other cultivars. The content of amino acids in the cultivars was relatively small. The content of theanine in the five cultivars was moderately low, but the contents of other major amino acids Higher; shoots are also rich in lysine and other essential amino acids; a variety of seasonal changes in amino acid law is obvious, the overall trend is spring high and low autumn
