Abstract

Abstract:

The essential oil composition of Osmanthus fragrans was analyzed qualitatively and quantitatively by gas chromatography- 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, hexadecanoic 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.

Key words: GC-MS, heuristic evolving latent projection(HELP), Osmanthus fragrans, essential oil
