鲜、干品芭蕉根挥发油化学成分的GC-MS分析

Study on Chemical Components of Essential Oils from Fresh and Dry Rhizoma Musae by Gas Chromatography-Mass Spectrometry

目的:分析比较新鲜和干燥芭蕉根挥发油的化学成分,为芭蕉根的开发利用提供参考。方法:采用水蒸汽蒸馏法分别提取来自同一植株的干、鲜品芭蕉根的挥发油,通过气相色谱-质谱联用法分析和鉴定化学成分。结果:鲜品芭蕉根挥发油中鉴定出36种成分,占总量的76.28%;而干品芭蕉根挥发油中鉴定出32种成分,占总量的81.78%。结论:两者的共有成分中,含量较高的是十五醛、角鲨烯和正庚醛,其在鲜品芭蕉根中的相对含量分别为19.60%,11.46%,8.69%,而在干品芭蕉根中则为17.37%,8.87%,5.07%。其他化学成分及其含量存在差异。

Objective：To analyze and compare the chemical constituents of the volatile oil from fresh and dried Rhizoma Musae.Method：Essential oils obtained by hydrodistillation from fresh and dried Rhizoma Musae which came from the same plant,was analyzed by GC-MS.Result：Thirty-six compounds were characterized,representing 76.28% of the fresh Rhizoma Musae volatile oil,whereas in the dried Rhizoma Musae oil,only 32 compounds were characterized,representing 81.78 %.Conclusion：Among them,the majority were pentadecanal,squalene and heptenal.Their relative content was 19.60%,11.46%,8.69% in fresh Rhizoma Musae oils and 17.37 %,8.87%,5.07 % from dried Rhizoma Musae,respectively.The relative contents of other chemical constituents were different
