Abstract: This paper deals with the chemical constituents of the absolute from flower of Osmanthus fragrans (GUI HUA). The constituents were determined by using the methods of GC-MS (EI, CI), fractional distillation, column chromatography, TLC and IR. 26 components have been identified, i.e. 1, 2-dimethyl benzene, 6-methyl-5-hepten-2-one, 3-hexenlyl formate, trans-linalool oxide, cislinalool oxide, linalool, megactigm-6, 8-dien-2,5-oxide, nonanol, terpineol, 3,4-dimethylheptane, 6-ethenyl tetrahydroxy-2,2,6,trimethylpyran-3-ol, nerol, dohydro-β-ionone, geraniol, α-ionone, benzylethanol, β-ionone, 3,7,11-triemethyl-l,6,10-dodecatrien-3-ol, m-ethylphenol, γ -decalacton, 9,12-octadecadienal ethyl palmitate, 3-hydro- xybenzoic acid methylester, 11,14,17-eicosatrienoic acid methylester.
