当归藤不同部位挥发油成分GC-MS分析

目的]研究当归藤不同部位中挥发油成分。方法]采用水蒸气蒸馏法分别提取当归藤根、茎、叶的挥发油成分,通过气相色谱-质谱联用法对这3个部位挥发油的化学成分进行对比研究,并用面积归一化法获得各化合物的相对含量。结果]从当归藤根中鉴定出11个成分,占挥发油总量的77.67%;从当归藤茎中鉴定出36个成分,占挥发油总量的92.88%;从当归藤叶中鉴定出74个成分,占挥发油总量的85.11%。结论]该方法结果准确可靠,为当归藤的质量标准制定及进一步开发利用提供了科学依据。

Study on the Chemical Constituents of Volatile Oil from Different Parts of Embelia parviflora Wall.ex A.DC.by GC-MS

Objective] To study the chemical constituents of volatile oil from different parts of Embelia parviflora Wall.ex A.DC.Method] The volatile oil was respectively extracted from the root,stem and leaf of E.parviflora by steam distillation and then analyzed by gas chromatography-mass spectrometry(GC-MS).The relative content of all isolated compounds was determined by area normalization.Result] 11 chemical constituents were identified from the root of E.parviflora,accounting for 77.67% of total volatile oil.36 chemical constituents were identified from the stem,accounting for 92.88%of total volatile oil.74 chemical constituents were identified from the leaves,accounting for 85.11% of total volatile oil.Conclusion] The study result was accurate and reliable,which could provide scientific basis for the establishment of quality standard,further development and utilization of E.parviflora.
