Objective: To obtain optimum extraction process of drug couple composed of Lonicerae Japonicae Flos and Forsythiae Fructus. Method: Examined extraction time
extraction times
concentration and the amount of ethanol with chlorogenic acid
luteolin
quercetin and forsythiaside as indexes by multi-index comprehensive evaluation method. Result: Optimal extraction technology of the drug couple was as followed: extracted 3 times with 8 times amount of 60% ethanol for 2 h each time. Conclusion: The optimum extraction technology could provide a reference to study on the extraction technology of drug couple composed of Lononicerae Japonicae Flos and Forsythiae Fructus.
