The essential oil composition of Osmanthusfragrans was analyzed qualitatively and quantitatively by gas chromatog-raphy-mass spectrometry(GC-MS) under the help of heuristic evolving latent projection(HELP). 48 components were identified accounting for 92.79% of the total area of peaks and the main compounds were α-methyl-α-[4-methyl-3-pentenyl] oxiranemethanol, β-linalool, lilac aldehyde, (E)-β-ionone, hexadecanoie acid, methyl salicylate contributing to 62.32% of total essential oil. The results show that overlapped peak clusters were resolved into pure chromatograms and pure mass spectra. Under assistance of the HELP method, the accuracy of qualitative and quantitative results was greatly improved.
