目的:考查红腺忍冬叶中有效成分含量动态积累过程,确定红腺忍冬叶药材的最佳采收时间。方法:采用高效液相色谱法考查红腺忍冬叶中的绿原酸含量积累情况,采用紫外分光光度法考查红腺忍冬叶中总绿原酸和总黄酮的含量积累情况。结果:在连续12个月中红腺忍冬叶药材的有效成分含量变化较大。结论:综合绿原酸、总绿原酸和总黄酮的含量确定红腺忍冬叶的最佳采收时间为11月。
OBJECTIVE: To investigate the process of dynamic accumulation of active ingredients in Lonicera macrophylla and determine the best harvesting time of Lonicera macrophylla. Methods: The content of chlorogenic acid in Ligusticum chongii was determined by HPLC, and the content of total chlorogenic acid and total flavonoids in Lonicera chingii was determined by UV spectrophotometry. Results: In the continuous 12 months, the content of active ingredients of Herba Lonicerae changed greatly. Conclusion: The best harvesting time of honeysuckle frugiperda was determined by the content of chlorogenic acid, total chlorogenic acid and total flavonoids in November.
