Fig. 1. Polyphenols/amino acids ratio (P/A) and its correlation with amino acids, catechins as well as theaflavins. (A) P/A values of tea samples. (B) Correlation coefficients between the P/A values and free amino acids. (C) Correlation coefficients between the P/A values and catechins as well as theaflavins. Data are expressed as mean ± SD (P = 3). Values followed by different letters and are significantly different (P < 0.05).*P < 0.05, **P < 0.01.
