Fig. 1From: Ethylene signaling modulates contents of catechin and ability of antioxidant in Camellia sinensisEffects of ethylene signaling on the content and degree of catechin galloylation in tea seedlings. a Caffeine and the four major catechins, EC, EGC, ECG, and EGCG, were detected. b Total catechin content. c The relative ratio was calculated as follows: ECG/(EC + ECG) and EGCG/(EGC + EGCG). Data points are mean ± SD of five biologically independent experiments. Asterisks indicate significant differences from the control sample (P < 0.05; Student’s t test)Back to article page
