Analysis Chemical Composition in Cycas Revoluta by GC-MS

Objective: Analysis chemical components in Cycas revolute. Method: The contents and chemical compositions of the fatty acids fom Cycas revoluta have been investigated and determined in this paper. Essential oil was extracted with petroleum ether. Extract oil was determined by GC-MS after the preparation of the methyl esters with BF3-CH3-OH. Result: The experimental results showed that there were 5 components of fatty acids in the oil of Cycas revolute by GC-MS. There are Linolenic acid (18.47%), Oleic acid (12.96%), Linoleic acids (10.9%), Palmitic acid (8.82%) and Octadecanoic acid (7.85%). Conclusion: The results reveal there are some important fatty acids in Cycas revolute and provide theoretical basis for chemical constituent research of Cycas revoluta and future extent research.
