Gu, Wen-Ting published the artcileNon-targeted metabolomic analysis of variation of volatile fractions of ginseng from different habitats by HS-SPME-GC-MS coupled with chemometrics, Formula: C10H20O2, the main research area is Panax metabolomic volatile compound chemometrics solid phase microextraction.
Cultivated ginseng (CG), transplanted ginseng (TG) and mountain cultivated ginseng (MCG) classified by the habitat type all belong to Panax ginseng and were reported to have similar types of secondary metabolites. Nonetheless, owing to the distinctly diverse habitats in which these ginseng types grow, their pharmacol. effects differ. In the present study, an emerging anal. approach involving headspace solid-phase microextraction-gas chromatog.-mass spectrometry (HS-SPME-GC-MS) was established to effectively distinguish among CG, TG and MCG. First, the volatile components were analyzed and identified by using the NIST library combined with measured retention indexes (Kovats′, RI), and a total of 78 volatile components were finally characterized, which included terpenes, alcs., esters, aldehydes and alkynols. Furthermore, multivariate statistical approaches, principal component anal. (PCA) and orthogonal partial least-squares discrimination anal. (OPLS-DA) were subsequently utilized to screen for compounds of significance. Under optimized HS-SPME-GC-MS conditions, 12, 16, and 16 differential markers were screened in the CG-TG, CG-MCG and TG-MCG groups, resp. Our study suggested that HS-SPME-GC-MS anal. combined with metabolomic anal. methods and chemometric techniques can be applied as potent tools to identify chem. marker candidates to distinguish CG, TG and MCG.
