Open publisher page 0 citations

Abstract

Objective:To screen the optimal extraction process and condition of Pulsatilla Decoction.Methods:The amounts of sediment of water-extraction were observed.The factors of affecting extraction of effective ingredients including the added amount of water,the extracting time and times of extraction were studied by orthogonal design with the yield rate of dry extract and content of berberine hydrochloric as the indicator.Results:the times of extraction were the most significant affecting factor.Conclusion:The optimum condition for the extraction of pulsatilla Decoction was 3 times extraction,0.5 h for extraction process and 9 times amount of water more than material medica.
