Analysis of Volatile Compounds From Leaves and Fruits of Lindera glauca

Objective:To analyze the chemical components of essential oil from leaves and fruits of Lindera glauca.Method: The essential oil was collected by solid-phase microextration(SPME).The chemical constituents were separated and identified by gas chromatography-mass spectrometry(GC-MS) combined with Kovats index.Result: Twenty-five and thirty-three species of chemical components were identified by GC-MS.The content of the identified compounds extracted from leaves and fruits were 96.51% and 99.73% of the total volatile substances,respectively.D-germacrene(45.56%),(+)-ledene(5.76%) and caryophyllene(5.75%) were the most abundant volatile compounds released from leaves.The main chemical components of the fruit were(Z)-3,7-dimethyl-1,3,6-octatriene(31.90%),copaene(12.75%),α-caryophyllene(8.06%).Fourteen compounds were owned in both leaves and fruits.Conclusion: The main volatile compounds from leaves of L.glauca are obviously different from fruits.
