Abstract

Abstract: The changes of non-galloylated catechins and relative enzymes as well as the composition of catechins in different parts of tea shoots and in different seasons were investigated in this paper. The results showed that the contents of non-galloylated catechins except GC increased gradually from bud to the fourth leaf. Both of two synthetical enzymes related to non-galloylated cahechins, the activity of DFR/LAR declined gradually, but the activity of ANR was the highest in the third leaf. The result of correlation analysis showed that the contents of total catechins in different tea leaves presented a prominent positive correlation with the activity of DFR/LAR,but not with the activity of ANR.

Key words: tea plant [Camellia sinensis (L.) O. Kuntze], non-galloylated catechins, different seasons, biosynthesis
