摘要(Abstract):

采用晒干、硫磺熏蒸、热风干燥、微波干燥、红外干燥以及各种联用技术干燥天麻药材,通过比较各样品的性状、浸出物、有效成分含量,考查不同干燥方法对天麻药材质量的影响。结果表明,硫磺熏蒸、热风干燥、热风微波联用干燥得到的样品性状特征较好;不同干燥方法对浸出物影响小,其中热风干燥处理后浸出物含量较高;硫磺熏蒸、单用微波干燥、单用红外干燥会造成二苯乙烯苷类成分转化和天麻多糖含量的下降。综合分析药材性状、活性成分含量、生产成本等因素,天麻药材的产地加工干燥方法以热风干燥或热风微波联用干燥为首选。
Different drying methods,including drying in the sun,sulphur fumigation,hot air drying,microwave drying,infrared drying and various coupling techniques,were used to dry fresh Gastrodiae Rhizoma. Characteristics,extracts and the contents of active components of all samples were compared to investigate the effects of different drying methods on quality of Gastrodiae Rhizoma. The results showed that the characteristics of the samples would be better with use of sulphur fumigation,hot air drying,and hot air-microwave drying. Different drying methods had little effects on extracts. Among them,the extract content was higher after hot air drying. The stilbene glycosides would transformation and the contents of Gastrodiae Rhizoma polysaccharides would decline with use of sulphur fumigation,microwave drying and infrared drying. In the comprehensive analysis of characteristics,content of active components,production cost and other factors,hot air drying or hot air-microwave drying was recommended as the first choice.
