“…Hydrogen and oxygen stable isotopes of plant materials are strongly linked to the climatic conditions (relative humidity, temperature and amount of precipitation) and geographical characteristics (distance from the sea or other evaporation source, altitude and latitude) of the area where the plants grew. [18,29,[41][42][43][44] East Africa (Uganda) shows significantly higher δ 18 O (Fig. 1) than the other macro-areas, while Peru and Asia have the lowest.…”

Stable isotope composition of cocoa beans of different geographical origin

The isotopic profile (δ(13) C, δ(15) N, δ(18) O, δ(2) H, δ(34) S) was used to characterise a wide selection of cocoa beans from different renowned production areas (Africa, Asia, Central and South America). The factors most influencing the isotopic signatures of cocoa beans were climate and altitude for δ(13) C and the isotopic composition of precipitation water for δ(18) O and δ(2) H, whereas δ(15) N and δ(34) S were primarily affected by geology and fertilisation practises. Multi-isotopic analysis was shown to be sufficiently effective in determining the geographical origin of cocoa beans, and combining it with Canonical Discriminant Analysis led to more than 80% of samples being correctly reclassified.

As much as the popularity of ginseng in herbal prescriptions or remedies, ginseng has become the focus of research in many scientific fields. Analytical methodologies for ginseng, referred to as ginseng analysis hereafter, have been developed for bioactive component discovery, phytochemical profiling, quality control, and pharmacokinetic studies. This review summarizes the most recent advances in ginseng analysis in the past half-decade including emerging techniques and analytical trends. Ginseng analysis includes all of the leading analytical tools and serves as a representative model for the analytical research of herbal medicines.

“…To date, this method has been successfully applied to determine the authenticity of various agricultural products (i.e., geographical origin: rice, vegetables, olive oil, juice, honey, wine, nut, tea; whether it is of organic origin: beef, milk; others: discrimination of cow milk vs. buffalo milk) [11], [12], [13], [14], [15], [16], [17]. In a prior study [18], the H isotope composition in ginseng was used to discriminate the geographical origin effectively between Korea and China. In particular, the negative value of N isotope composition in ginseng collected at Incheon, Korea was indicative of the application of synthetic fertilizer, possibly urea.…”

“…Few studies [18], [19], to our knowledge, have investigated the authenticity of ginseng using the analysis of light element isotope composition. Therefore, in the present study, we have measured the difference and variation of C, N, and S stable isotope ratios in 6-yr-old ginseng root depending on ginseng cultivation conditions (i.e., cultivation soil type and fertilizer type/amount).…”

BackgroundThe natural ratios of carbon (C), nitrogen (N), and sulfur (S) stable isotopes can be varied in some specific living organisms owing to various isotopic fractionation processes in nature. Therefore, the analysis of C, N, and S stable isotope ratios in ginseng can provide a feasible method for determining ginseng authenticity depending on the cultivation land and type of fertilizer.MethodsC, N, and S stable isotope composition in 6-yr-old ginseng roots (Jagyeongjong variety) was measured by isotope ratio mass spectrometry.ResultsThe type of cultivation land and organic fertilizers affected the C, N, and S stable isotope ratio in ginseng (p < 0.05). The δ15NAIR and δ34SVCDT values in ginseng roots more significantly discriminated the cultivation land and type of organic fertilizers in ginseng cultivation than the δ13CVPDB value. The combination of δ13CVPDB, δ15NAIR, or δ34SVCDT in ginseng, except the combination δ13CVPDB–34SVCDT, showed a better discrimination depending on soil type or fertilizer type.ConclusionThis case study provides preliminary results about the variation of C, N, and S isotope composition in ginseng according to the cultivation soil type and organic fertilizer type. Hence, our findings are potentially applicable to evaluate ginseng authenticity depending on cultivation conditions.
