Study on dynamic accumulation of secondary metabolites content and isoenzyme activity during blossoming stages in Chrysanthemum morifolium originating from Wenxian county / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the anabolic rule of secondary metabolites and dynamic activity of isoenzyme in Chrysanthemum morifolium originating from Wenxian county during blossoming stages.</p><p><b>METHOD</b>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.</p><p><b>RESULT AND CONCLUSION</b>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%.</p>
