Comparing the production capacity of TFs, TRs, and TBs in different varieties of tea leaves (Figures 3(a)-3(c)), Yinghong 9 and Hongyan 12 had a higher capacity of producing TFs than other varieties, which was closely related to the highly active PPO and POD (Figures 1(a) and 1(b)) and higher content of catechins (Figure 2); Yinghong 9 had a higher enzymatic activity than other varieties, and in addition to the higher content of catechins, it could produce the most TRs; although Longjing 43 had a higher content of catechins, its enzymatic activity was low, so the production of TRs was significantly the lowest; the production of TRs was significantly associated with the content of catechin substrate and PPO and POD activity [15].
