ABSTRACT
Objective Gas chromatography-mass spectrometer (GC-MS) technology combined with Heuristic evolving latent projections (HELP) method were used to qualitatively analyze the volatile oil of fructus lycii (Lycium barbarumL.)Methods With the best temperature-programmed chromatographic condition, overlapping peaks among the total ion chromatogram were separated. Then an automatic mass spectral deconvolution and identification system (AMDIS) was used to identify volatile components comprehensively. Finally, the pure chromatographic peaks were matched with NIST 05a mass spectra library for giving the precise qualitative result. Results Totally, 29 compounds in fructus lycii (Lycium barbarum L.) were identified accurately.Conclusions Compared with the traditional qualitative analysis method, the new established method which GC-MS technology combined with HELP could get tremendous advantages. It not merely enhanced the accuracy of identification but also solved the bottleneck of handling the inseverable compounds.
