Increased anti-oxidant capability of yeast upon dendrobine treatment. A Growth status of BY4741 yeast under oxidative stress induced by 9.5 mM H₂O₂; B The survival rates of BY4741 yeast under oxidative stress induced by 5.5 mM H₂O₂; C, D The levels of ROS (C) and MDA (D) in BY4741 yeast upon dendrobine treatment at 24 and 48 h; E–H The effect of dendrobine on anti-oxidant enzyme activities in BY4741 yeast at 24 and 48 h. The experiment was repeated three times and data from each experiment are displayed as mean ± SEM. The repeats number of each group was five. ^*, ^**, ^*** represent significant difference compared with negative control (p < 0.05, p < 0.01, p < 0.001)
