摘要
用水蒸气蒸馏法提取莪术挥发油 ,通过正交试验设计法优选获取莪术挥发油的技术参数 ,结果表明 ,以药材粗粉为原料 ,按m (药材 )∶m (水 ) =1∶8加水 ,蒸馏 8h ,药材出油得率平均可达2 .5 1% ,该工艺稳定、可靠 .莪术挥发油的GC
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.
