Study on Different Extraction Processes of Chlorogenic Acid in Flos Lonicerare and Optimum

We summed up the common methods of the extraction process of chlorogenic acid in Flos Lonicerare to determine the optimal method of extracting chlorogenic acid with the results:The extraction process of ethanol B is optimum.The optimum extraction conditions are 6 fold of 40% ethanol,pH=6,dip in 80℃ water,refluxing 2.5h.The content of chlorogenic acid is fairly high.
