气相色谱-质谱法分析4种方法提取没药所得提取物的化学成分

目的:为进一步研究没药提供参考。方法:采用气相色谱-质谱法分别对超临界CO2萃取法、索氏提取法、超声提取法和水蒸气蒸馏法提取没药所得提取物的化学成分进行比较分析。结果:各提取方法所得提取物成分差异很大,以超临界CO2萃取物中化学成分和种类较多,除挥发油外还有大量树脂等有效成分;超临界CO2萃取法可避免提取过程中的高温和有机溶剂残留。结论:超临界CO2萃取法可初步判定为适用于没药的提取方法。

Analysis of Chemical Compositions of Myrrha Extractives(Extracted by 4 Different Ways)by GC-MS

OBJECTIVE:To provide references for the further study of myrrha.METHODS:The chemical components of myrrha extractives exteracted by super-borderline CO 2 extraction method,soxhlet extraction method,supersound extraction method and water vapor distillation method were analyzed comparatively by GC-MS.RESULTS:The components of extracˉtives extracted by different ways were very different,with more chemical compositions and more varieties in the super-borˉderline CO 2 extractives-there were great amount of resin besides volatile oil;high temperature and organic solvents residual could be avoided in the extracting process by super-borderline CO 2 extraction method.CONCLUSION:Super-borderline CO 2 extraction method was initially assessed to be a suitable extraction method of myrrha.
