Analysis of the volatile components of Agrimonla Pilosa Ledeb by gas chromatography-mass spectrometry

Based on chemometric resolution methods, a method for qualitative and quantitative determination of the volatile components in Agrimonla Pilosa Ledeb was developed by chromatography-mass spectrometry. The overlapping chromatographic peaks were resolved into pure chromatograms and spectra with heuristic evolving latent projections (HELP), qualitative analysis was performed by similar search in NIST library with the obtained pure mass spectrum of each component and the quantitative results were obtained by calculating the volume of total two-way response. The results show that 56 components are separated and 50 components are identified, accounting for 90.53% of the total content. The main components are alcohols and monoterpene, accounting for 50.58% and 18.34% of the total content, respectively. The present method can be used to provide useful information for further study and development of Agrimonla Pilosa Ledeb.
