摘　　要：对孝昌县11个引进茶树[Camellia sinensis (L.) O. Ktze.]品种的春梢1芽2叶制成的冻干样品进行了水浸出物、咖啡碱、游离氨基酸、茶氨酸、茶多酚、儿茶素含量分析,并计算出了酚氨比。结果表明,水浸出物含量45.56%~53.56%;咖啡碱含量24.60~38.64 mg/g;游离氨基酸总量25.17~79.80 mg/g;茶氨酸含量2.78~31.10 mg/g;茶多酚含量127.30~242.22 mg/g;儿茶素含量85.52~177.21 mg/g;酚氨比1.60~9.62。不同茶树品种春梢1芽2叶生化成分含量有所不同。相比较而言,安吉白茶、多抗香、舒茶早和仙寓早4个品种明显表现出高氨基酸含量、低茶多酚含量的生化特征,更适合制作高档优质绿茶。The biochemical components including water extracts,caffeine,free amino acid,theanine,poly phends and catechin in the one bud and two leaves of spring shoots of 11 tea[Camellia sinensis （L.） O. Ktze.] eultivars were analyzed;and the ratio of tea poly phenols and amino acid was calculated. The results showed that the content of water extracts was 45.56% to 53.56%;the content of caffeine was 24.60 to 38.64 mg/g;the content of free amino acid was 25.17 to 79.80mg/g;the content of theanine was 2.78 to 31.10 mg/g;the content of tea poly phenol was 127.30 to 242.22 mg/g;the content of eateehin was 85.52-177.21 mg/g;and the ratio of tea poly phenols and amino acid was 1.60 to 9.62. The content of the biochemical components in the one bud and two leaves of spring shoots of different tea varieties is different. In comparison, Anji white tea, Duokangxiang,Shuehazao and Xianyuzao have obvious biochemical characteristics of high amino acid content and low tea polyphenol content,are more suitable for making high quality green tea.
