中药煎药机对饮片中挥发性成分煎出量影响的研究

目的:通过比较薄荷、徐长卿、肉桂、丁香、牡丹皮5种含挥发性成分饮片在不同煎药时间点、使用3种不同煎药方式(传统砂锅后下、中药煎药机后下及中药煎药机正常煎煮)时汤液中的挥发性成分煎出量大小,明确使用中药煎药机煎煮含挥发性成分饮片的煎药方法。方法:利用HPLC-GC测定汤液中挥发性成分含量,使用SPSS 13.0统计软件分析不同煎药方式下挥发性成分煎出量的差异性。结果:汤液中挥发性成分的含量中药煎药机大于传统煎药工具,存在极显著差异(P<0.01);中药煎药机后下与正常煎煮2种煎药方法对挥发性成分含量影响不显著(P>0.05)。结论:中药煎药机煎煮含挥发性成分饮片时可随复方其他饮片一起煎煮而不必采用"后下"方法;传统煎药方法煎煮此类饮片时"后下"是必要的、科学的。

Effects on Traditional Chinese Medicine Extracting Machine on Decocting Volume of Volatile Components in Pieces of Chinese Medicine

Objective: By comparing the different infiuence to the quantity of volatile coponents in the decoction of Spear Mint,Swallowwort Root,Cinnamoni,Lilac and Cortex Moutan Radicis,which have been gained by three different way(thoes pieces added behind in traditional and earthen pot and Chinese medicine extracting machine,and added innormal way in Chinese medicine extracting machine)in different decocting time pot.The method of extracting volatile components in piecesof chinese medicine in traditional chinese medicine extracting machine has been determined. Method: Decocting volume of volatile components in decoction was determined by HPLC-GC,and the difference of decocting volume of volatile components in different extracting methods are analysised by statistical software SPSS 13.0. Result: There are very signficent differences(P<0.01)on the content of volatile components in different decoctions of having been made by using traditional chinese medicine decoting machine and the traditional decoting tools.However,results of the pieces of traditional chinese medicine which contain volatile components added behind into traditional chinese medicine decoting machine and the regular mean has no apparent differences(P>0.05). Conclusion: The pieces of traditional chinese medicine composing volatile components could be extrated with other pieces,but it is necessary and scientistic to added behind for extrating those pieces in the regular means.
