重庆垫江牡丹皮丹皮酚含量动态变化研究

Dynamic Changes Analysis on Paeonol in Cortex Moutan from Chongqing Dianjiang County

目的研究不同因素引起垫江牡丹皮中主要有效成分丹皮酚的变化规律和动态特征。方法采用高效液相色谱法测定不同因素下牡丹皮样品中丹皮酚含量,并对其变化规律进行动态分析。结果丹皮酚含量从海拔400m^800m呈抛物线型变化,以600m含量最高;从生长年限3y^5y逐年升高;从采收期8月份~11月份呈抛物线型变化,10月份最高。结论海拔400m^800m均适宜牡丹种植,600m左右为最适宜种植区域,以10mo上、中旬采收4y和5y生牡丹皮为宜。

OBJECTIVE： To study the content change regularities and the dynamic characteristics of paeonol, the major active ingredients in Cortex moutan from Chongqing Dianjang county under different influencing variables.METHODS： The determination of paeonol in moutan cortex samples was conducted by HPLC,and dynamic analysis on content change regularities was conducted .RESULTS：The content of paeonol took a para- curve pattern at an altitude from 400m to 800m,with that from 600m in altitude has the highest content ;The content increased year by year from growing life of 3 to 5 years;The content took a para-curve pattern when harvested from 8mo to llmo, with that harvested in 10mo was the highest.CONCLUSION： The optimal altitude for the growing of Cortex moutan was from 400m to 800m, in particular at an altitude of 600m, and it is preferable to harvest Cortex moutan with 4 or 5 years growing life in the first 20 days of 10mo.
