摘要:

目的 确立商洛半夏产地加工的干燥工艺,为制订半夏药材生产标准操作规程(SOP)提供数据支撑。方法 将新采挖的鲜半夏随机等分为4组,分别采用阴干、晒干、60 ℃烘干、微波4种方法进行干燥,以半夏出干率、L-左麻黄碱、水溶性浸出物的含量为观察指标,分别测定其有效成分的含量。结果 半夏采挖后,洗净,去皮,分别用4种方法干燥,以微波中火3 min干燥,半夏出干率、L-左麻黄碱的含量最高。结论 生产中半夏药材干燥以微波法为好,既降低劳动强度、节省干燥时间,又提高有效成分含量。

Abstract:

OBJECTIVE To establish the processing Shangluo Pinellia origin drying process, for making medicine production standard operating procedure (SOP) to provide data support. METHODS The freshly mined Pinellia was randomly divided into four groups, using the methods of drying in the shade,the way of airing, drying in 60 ℃ and microwave.Taking pinellia doing rate, L-Left ephedrine,the leaching of water-soluble content as the observation target.And then the content of effective components were determined.RESULTS After being mined,Pinellia was cleaned,peeled of the four methods of drying,microwave in fire 3 min,Pinellia doing rate and the L- left ephedrine content were highest. CONCLUSION In producing Pinellia as a Chinese herbal medicine,we'd better use the method of microwave,which reduces labor intensity,saves drying time, also enhances the effective component content.
