Abstract:
Objective: To optimize the alcohol-extraction process and condition of Radix Pulsatillae.Methods: Alcohol concentration,the extraction time and number of extraction on effect of extraction rate of pulchinenoside B4 were evaluated by orthogonal design L9(34).Results: The optimum condition of the alcohol extraction was: 75% ethanol,3 times of extraction,3h for extraction process.Conclusion: The extraction method can be used for reference for the extraction process of Radix Pulsatillae.
