| Abstract: | In order to enhance the extraction ratio of Chlorogenic acid（CA） from Flos Lonicerae,the effects of extraction temperature,ethanol concentrations,extraction time and the ratio of solid to extraction solvent amount（w/v） were investigated in single factor experiment（SFE）.With orthogonal test,the optimal extraction parameters were determined as the following：70% ethanol as the extractant,the temperature is 60℃,the mixture ratio is 1∶15,the extracting time is 15min.Under the above conditions,the extraction ratio can reach up to 1.353%. |
