Abstract: The contents of free amino acids in 230 flat tea samples were measured by full-automatic amino acid analyzer and statistical analysis were performed. The results showed that two functions and six variables were obtained by discriminant analysis of Longjing Group,Longjing 43 and Wuyi Early Tea. The correct rate of discrimination for training set was 64.3%,and the correct rate of cross-validation was 63.5%. A preliminary distinction could be made between Longjing 43 and Wuniuzao.

Key words: flat tea, free amino acids, principal component analysis, discriminant analysis.
