To study the anabolic rule of secondary metabolites and dynamic activity of isoenzyme in Chrysanthemum morifolium originating from Wenxian county during blossoming stages.
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.
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%.
研究温县产菊花花期次生代谢产物的合成规律及同工酶的动态活性。
测定温县产菊花花期黄酮类、绿原酸和花青素含量以及苯丙氨酸解氨酶（PAL）、多酚氧化酶（PPO）和过氧化物酶（POD）活性。
两个品种的菊花中，黄酮类和绿原酸含量在花朵开放70%时最高，花青素含量在花朵开放50%时最高，PPO活性在花朵开放30%时最高，呈现相同趋势。两个品种之间，PAL和POD的变化趋势不同。“怀大白菊”PAL和POD活性最高值分别出现在花朵开放70%和30%时，而“怀小白菊”则出现在花朵开放50%时。
