摘要
目的:比较牡丹皮药材的几种常用提取方法,以获得最适提取工艺。方法:采用醇提法、蒸馏 煎煮法、CO2 超临界流体萃取法及传统煎煮法对牡丹皮进行提取,并依据总提取物收率、丹皮酚收率、其他成分提取情况、实际生产可行性等,对实验结果进行分析。结果:所用方法的总提取物收率依次为12 .6 6 % ,13. 5 1% ,7 .2 8% ,7 .5 6 % ,丹皮酚收率依次为2 . 4 5 % ,2. 2 6 % ,0 . 31% ,1. 15 % ;除CO2 超临界流体萃取法外,其他方法均能检出酚苷类成分。结论:蒸馏 煎煮法是牡丹皮药材目前最适提取方法。
Objective: To obtain the optimized extraction technology of Paeonia suffruticosa by comparing several extraction method. Method: Extract P. suffruticosa by ethanol circumfluence, distillation-decoction, CO 2-SFE and traditional decoction, and analyse the results according to the total extraction rate, extraction rate of paeono,extraction of other ingredients and production feasibility. Result: Total extraction rates of which are 12.66%, 13.51%, 7.28%, 7.56% respectively; extraction rates of paeonol are 2.45%, 2.26%, 0.31%, 1.15% in turn; Phenolic glycosides can be extracted by ethanol circumfluence, distillation-decoction, traditional decoction, but not by CO 2-SFE. Conclusion: Distillation-decoction is the most proper extraction technology of P. suffruticosa at present.
