Analysis of Chemical Compositions of Myrrha Extractives(Extracted by4Different Ways)by GC-MS / 中国药房

ABSTRACT

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 extrac?tives extracted by different ways were very different,with more chemical compositions and more varieties in the super-bor?derline 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.
