湘蕾金银花最佳采收时间和干燥方法的研究

The Research on Xianglei Honeysuckle's Best Picking-up Time and Dehydrating Method

目的确定湘蕾金银花最佳采收时间和干燥方法。方法采用高效液相色谱法测定花蕾的绿原酸含量。结果不同时间采收的湘蕾金银花花蕾绿原酸的含量以随着花蕾增长而下降;一天中不同时间采收的花蕾绿原酸含量以清晨为高;不同干燥方法湘蕾金银花花蕾绿原酸的含量以手工炒干法最高,直接烘干法最低。结论湘蕾金银花最佳采收时间宜在6月27日左右;一天中以清晨采收为佳;最佳干燥方法为杀青烘干法。

Objective To identify the best picking - up time and dehydrating method of Xianglei Honeysuckle. Methods The content of chlorogenic acid in buds of Honeysuckle was assayed by HPLC. Results With growth of buds, the content of chlorogenic acid decreases, the content of chlorogenic acid reaches the maximum in those Honeysuckle picked in early morning, also, after different dehydrating methods, the content of chlorogenic acid in buds varies a lot, manually fried buds contain the largest amount of chlorogenic acid while directly fried ones contain the least. Conclusion The best time for picking - up Honeysuckle is about June 27th, especially in early morning, and the best dehydrating method is ShaQing Dehydrating.
