Abstract:
Objective:The best operation condition of extraction was found through analyzing the influences of both process of microwave pretreatment and hot wave washing. Methods: A new extraction method of chlorogenic acid was that the dry FLos Lonicerae was humidified with 75% ethanol-water solution at first, then the wet Flos Lonicerae was rapidly vaporized by microwave heating, at last chlorogenic acid was extracted after hot water washed twice, 10 minutes each time. Results: Compared with traditional extraction, the extraction time was about less than 6 times and then extraction ratio was increased by 1%. Conclusion: The method has high rate of extraction and short time of extraction.
