Abstract: Two liposoluble constituents (extract I and extract II) from leaves and stems of Drypetes cumingii were isolated by solvent extraction method and silica column chromatography.The chemical constituents of these two extracts were analyzed using gas chromatography-mass spectroscopy (GC-MS).15 compounds were identified from the extract I,mainly comprised ester compounds (61.54%).32 compounds were identified from the extract II,and the major constituents were terpenoids (19.72%).It was the first report to study on lipophilic chemical constituents of D.cumingii.The results showed that the ethyl acetate fraction of D.cumingii contained ethyl oleate and nerolidol,which were acted as important raw materials in chemical industry.In addition,squalene and disparlure (normally used in pest prevention) with large quantities were also detected the ethyl acetate fraction of D.cumingii.
