Analysis of the Volatile Chemical Constituents of Agrimonla pilosa Ledeb with Gas Chromatography-Mass Spectrometry and Heuristic Evolving Latent Projections

Analysis of the volatile components in Agrimonia pilosa Ledeb with heuristic evolving latent projections (HELP) was presented. After extracted with water distillation method, the volatile components were detected by GCMS. Then the qualitative and quantitative analysis of the volatile components was completed with HELP resolving two-dimensional original data into mass spectra and chromatograms. 62 of 83 separated constituents in the total ion chromatogram of the volatile components were identified and quantified, accounting for about 86.49% of the total content. The obtained information can provide foundation for further study of Agrimonia pilosa Ledeb. This developed method can also be used for quality control of Agrimonia pilosa Ledeb samples.
