川藿香与广藿香挥发油化学成分GC-MS对比分析

目的: 对比分析川藿香和广藿香挥发油化学成分。方法: 采用水蒸气蒸馏法提取挥发油,并运用GC-MS进行分离测定,结合质谱库检索技术对化合物进行结构鉴定,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: 川藿香挥发油中分离出88种成分,鉴定出45种化学成分,占总含量的93.81%;广藿香中分离出92个成分,鉴定出22个化学成分,占总量的85.80%。结论: 采用GC-MS联用技术对川藿香和广藿香挥发油化学成分进行对比分析,二者差异较大。

Analysis of the Chemical Constituents of Essential Oil between Agastache rugosa and Pogostemon cablin by GC-MS

Objective: The chemical components of essential oil from Agastache rugosa and Pogostemon cablin was analyzed by GC-MS. Method: The components were isolated and identified by GC-MS. The components were identified by their mass spectra. The relative content in percentage were calculated from the GC peak areas. Result: Forty-five and twenty-two components were identified in the essential oil of A. rugosa and P. cablin extracted by steam distillation. Conclusion: This paper reports the composition of essential oil between A. rugosa and P. cablin for the first time.
