摘要(Abstract):

目的:研究微波辅助萃取全草及根皮类等不同部位中药材的最佳工艺。方法:分别以总黄酮、丹皮酚为考察指标,采用均匀设计优选微波辅助萃取鬼针草及牡丹皮药材的工艺。结果:优选出微波辅助萃取鬼针草中总黄酮的工艺条件为:微波功率850 W,提取时间30 m in,溶剂浓度40%,液固比13∶1,浸泡时间60 m in;牡丹皮中丹皮酚的工艺条件为:微波功率340 W,提取时间20 m in,溶剂浓度85%,液固比例为5∶1,浸泡时间30 m in。结论:微波辅助萃取技术适合于全草类药材鬼针草、根皮类药材牡丹皮中有效成分的提取。
Objective:To study the optimization process of microwave-assisted extraction for active ingredients in different parts of TMC.Method:Using the uniform design,the optimization processes of microwave-assisted extraction for Flavonoids and Paneonolum in Bidens and Cortex Moutan were gained.Result:The optimization process of extraction for Flavonoids in Bidens can be described as following:microwave power was 850 W,radiation time was 30 min,solvent concentration was 40%,solvent volume was 13 times as the proportion of raw material,and dipping time was 60 min.The optimization process of extraction for Paneonolum in Cortex Moutan has also been gained which could be shown as following:340 W as microwave power,20 min as radiation time,85% as solvent concentration,1∶5 as the proportion of raw material to solvent,and 30 min as the dipping time.Conclusion:These can prove it reasonable to get active ingredients in Bidens and Cortex Moutan with microwave-assisted extraction technology.
