Background : The geographical origin of Panax ginseng Meyer, a valuable medicinal plant, is important to both ginseng producers and consumers in the context of economic profit and human health benefits. We therefore aimed to discriminate between the cultivation regions of ginseng using the stable isotope ratios of C, N, O, and S, which are abundant bio-elements in living organisms. Methods and Results : The C, N, O, and S stable isotope ratios were measured by isotope ratio mass spectrometer, and then these isotope ratios profiling was statistically analyzed with chemometrics. The various isotope ratios found in Panax ginseng roots were significantly influenced by region, cultivar, and the interactions between these two factors (P ≤ 0.0002). In particular, δ18O was lower in ginseng roots grown at high altitudes (r = −0.47), while δ34S was higher in ginseng roots grown close to coastal areas (r = −0.48). Chemometric results provided discrimination between the majorities of different cultivation regions. Conclusion : Our case study extends the understanding about the variation of C, N, O, and S stable isotope ratios in ginseng root depending on cultivation region. Hence, the analysis of stable isotope ratios is a suitable tool for discrimination between the regional origins of ginseng samples from Korea, with potential application to other countries.
