Objective To compare the content of chlorogenic acid ( CGAs) in Flos Lonicerae of different periods. 目的比较金银花从花蕾到开花的过程中绿原酸的含量变化。
A comparison was made on the extraction of chlorogenic acids ( CGAs) from honeysuckle flower with different concentrations of ethanol and on the purification with ethanol precipitation method. 对不同溶剂提取金银花中绿原酸类物质的效果进行了比较。
Results The content of CGAs in buds of honeysuckles is 7.86%, and it is higher than that in the flowers. 结果金银花花蕾中绿原酸的含量较高,达7.86%。
