Objective: To study the anabolic rule of secondary metabolites and dynamic activity of isoenzyme in Chrysanthemum morifolium originating from Wenxian county during blossoming stages.
Method: The flavonoid, chlorogenic acid and anthocyanin content as well as the PAL, PPO and POD activity were determined in C. morifolium originating from Wenxian county during blossoming stages.
Result and conclusion: The content of flavonoid and chlorogenic acid was the highest at 70% of full blossom, the anthocyanin at 50% and PPO activity at 30% with the same trend of two cultivars. Between the two cultivars, the trend of PAL and POD was different. The highest of "huaidabaiju" appeared at 70% and 30%, but that of "huaixiaobaiju" appeared at 50% and 50%.
