摘要 为给消费者选择适合品饮的古树茶提供参考依据,本试验以西双版纳、普洱、临沧地区具有代表性的7个古树茶山的古树茶为试验对象,分别检测茶多酚、氨基酸、茶色素和黄酮等主要化学成分的含量。结果表明,云南不同产地的古树茶内含物质有明显差异,其中茶多酚、氨基酸和茶黄素的含量在(p <0.05)水平差异达显著,黄酮的含量的(p <0.01)水平差异不显著。结合感官审评结果,临沧地区的古树茶由于茶多酚含量较高(38.89%~44.26%),其滋味比其他两个地区的古树茶苦涩;普洱迷帝的古树茶氨基酸含量最高,达3.75%,滋味苦涩回甘,与其他产地相比鲜爽度更高;西双版纳地区和普洱景迈山的古树茶内含物质组成较协调,滋味苦涩回甘、醇滑。 In this paper,the content differences of main substances in ancient tea from different places were studied to provide reference basis for consumers torationally choose ancient tea suitable for their drinking.In this experiment,the contents of tea polyphenols,amino acids,tea pigments and flavonoids in ancient tea from seven representative ancient tea mountains in xishuangbanna,pu'er and lincang regions were detected.The results showed that there were significant differences in the contents of tea polyphenols,amino acids,and theaflavins in ancient tea from different origins,with significant differences in the contents of tea polyphenols,aminoacids,and theaflavins(p 0.05),and no significant differences in the contents of flavonoids(p 0.01).In combination with sensory evaluation,the lincang area of ancient tea because of the high concentration of tea polyphenols,from 38.89% to 44.26%,its taste compared with the other two regions of bitter,pu'er Midi emperor ancient tea amino acid content is the highest,at 3.75%,its the sweet taste bitter,compared with other regions is crisp,xishuangbanna region and pu'erJingmaishan ancient tea contains composition is coordinated,the sweet taste bitter,alcohol and smooth.
