Analysis on chemical constituents of essential Oil from hawthorn leaves by GC-MS

Objective To analyze the chemical components of essential oil from hawthorn leaves.Methods Essential oil was extracted by steam distillation.The chemical components of essential oil were analyzed by GC-MS and Kovats index.The relative contents of the components were determined with area percentage method.Results 154 components were separated and 93 components were identified.The main components in the oil were 2,7(14),10-bisabolatrien-1-ol-4-one(18.42%),nezukol(6.25%),trans-sabinene hydrate(4.11%),citronellyl propanoate(2.8%),zonarene(2.65%) and(5E,9E)-farnesyl acetone(2.5%) and so on.Conclusions This is the first time to adopt GC-MS and Kovats index to analyze the chemical components of volatile oil of hawthorn leaves,and this study can provide science basis for further research development of this plant.
