Abstract

The method of steam distillation was carried out to extract the volatile oil from Rhizoma curcumae . The extraction process was optimized by orthogonal design. The best condition was: using Rhizoma curcumae rough powder as raw material, adding 8 folds of water, and extracting for 8 hours. This optimized process was stable and highly efficient, and the average extract rate of the volatile oil was about 2.51%.The main compounds of volatile oil were Sesquiterpenes which was identified by GC MS.
