鲜品芭蕉根榨汁液与干品芭蕉根水煎液石油醚提取物的GC-MS分析

Study on the Chemical Constitutions of Petroleum Ether Extract from Fresh Rhizoma Musae Juicer Liquid and Dry Rhizoma Musae Decoction by GC-MS

目的:探索芭蕉根治消渴重鲜品榨汁液而非干品水煎液的原因,为芭蕉根的合理利用提供参考。方法:参照芭蕉根的临床应用,采用石油醚对鲜品芭蕉根的榨汁液与干品芭蕉根的水煎液进行提取,利用气相色谱-质谱法分离并分析鉴定其成分,应用色谱峰面积归一化法计算各成分的相对百分含量。结果:鲜品芭蕉根榨汁液的石油醚提取物中鉴定出54个化学成分,其中棕榈酸相对含量为3.13%;而干品芭蕉根水煎液的石油醚提取物中只鉴定出4个化学成分,棕榈酸相对含量高达25.60%。结论:古今文献记载治消渴重用鲜品(生)芭蕉根榨汁液而非干品芭蕉根水煎液,具有一定的科学、合理性。

Objective： Explore the Rhizoma Musae treating Xiaoke emphasis on the fresh juicer liquid instead of dry goods decoction reasons to provide a reference for the rational utilization of Rhizoma Musae.Method： According to the clinical applications of Rhizoma Musae,petroleum ether was used to extract fresh juicer liquid and dry goods decoction,and the chemical compositions were separated,analyzed and identified by gas chromatography-mass spectrometry;peak area normalization method was applied to calculate the relative percentage of the respective components.Result： There were 54 chemical compositions identified in the petroleum ether extract of fresh juicer liquid.The relative content of palmitic acid was 3.13%.However,only 4 chemical compositions were identified in the petroleum ether extract of dry goods decoction,the palmitic acid relative content was up to 25.60%.Conclusion： The study results show that the ancient and modern literatures recorded the usage of Rhizoma Musae juicer liquid to cure ‘Xiaoke’rather than dry goods decoction have a certain scientific reason.
