| Abstract: | Objective To establish the optimum extraction process for YSWWN. Methods The extraction process was studied by orthogonal design with the extract yeild of Paeoniflorin content as markers. Results The optimum extraction process was adding 18 times amont of 55% alcohol, refluxing and extracting for 2 times, 1.5h each time. The extraction process could raise the yield of Paeoniflorin content. Conclusion This extraction process shows higher yeild of Paeoniflorin content, good stability and is available for industrial production. |
