从姜黄及姜黄浸膏中提取的挥发油化学成分研究

The volatile oil was extracted from Curcuma longa and Turmeric oleoresin by Soxhelt method with petroleum ether.All the volatile oil was analyzed of chemical component by the method of GC-MS,the relative contents of these compounds were calculated using square peaks to normalization.On the volatile oil of Curcuma longa 35 peaks were separated and 21 compounds were identified,which accounted for 89.10%,the main chemical constituents was (-)-Zingiberene(22.12%),β-Sesquiphellandrene(15.24%),α-Turmerone (11.30%),β-Turmerone (8.87%),Ar-turmerone(8.20%),but on the volatile oil of Turmeric oleoresin 32 peaks were separated,of which 21 compounds were identified,which accounted for 90.12% the main chemical constituents was (-)-Zingiberene(23.92%),β-Sesquiphellandrene(15.73%),Ar-turmerone(12.89%),β-Turmerone(10.85%).
