This study used methanol as extraction solvent and eluent, using XAD-4 macroretcular resin as adsorbent, using gas chromatography - mass spectrometer, respectively assayed the organic components of panax rhizosphere soil, panax root exudates and decomposed panax products, the results showed: rhizosphere soil were effectively identified seven kinds of components, and panax root exudates were identified eight kinds of components, decomposed panax products were identified eight kinds of components. Through literature search, we found that most of them belonged to plant allelochemicals. 8-pentadecanone and tridecanoic acid methyl ester identified from panax rhizosphere soil and n-hexanoic acid, n-hexanoic acid and 2-methyl-hexanoic acid identified from decomposed panax products were not reported in the previous allelochemicals study, this kinds of components may be panax specific allelochemicals. Its formation and its function´s mechanism needed further research.
