“…From these points of view, the development of techniques to determine geographic origin is highly desirable for consumers, agricultural farmers, retailers and administrative authorities. Thus, the first technique for determining the geographic origin of Welsh onions (Allium fistulosum L.) was developed in 2004 [4][5][6] . The analytical manual for Center for Food Quality, Labeling and Consumer Services to monitor merchandise in the Japanese market was compiled and published on the internet in 2005 9 .…”

Scientific techniques for determining the geographic origin of agricultural products have attracted considerable attention in recent years. The most popular origin-determining technique is based on the composition of inorganic elements, and the technique has been applied to Welsh onions (Allium fistulosum L.). The technique on Welsh onions has been developed and compiled in a manual for monitoring market merchandise earlier than other origin-determining techniques in Japan. This technique makes use of chemometric analysis on concentration ratios of 19 elements (Na, P, K, Ca, Mn, Fe, Cu, Zn, Sr, Ba, Co, Ni, Rb, Mo, Cd, Cs, La, Ce, and Tl) to Mg to determine whether the geographic origin of Welsh onions sold in Japan is Japan or China. The technique is quite practical in that it can screen geographic origin within 2 days by the analysis of inorganic elements by inductively coupled plasma optical emission spectrometry and inductively coupled plasma mass spectrometry.

“…Each data in the chart was shown as relative concentration. Principal component analysis (PCA) and soft independent modeling of class analogy (SIMCA) were used as exploratory techniques and classification procedures, respectively [6]. Variables such as Na, Mg, Al, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ge, As, Mo, Hg and Pb have been used as discriminating factors.…”

Quality and safety issues related to traditional animal medicine: role of taurine

et al. 2010

BackgroundCalculus Bovis (:C.Bovis) is one of the most precious and commonly-used medicinal materials in Japan and China. As the natural occurrence is very rare, a source of supply for C. Bovis is far behind the actual need and great efforts have been taken for some substitutes of natural C. Bovis. Unfortunately, very little information is available on the quality and/or clinical efficacy of medication based on C. Bovis. To ensure sustainable use of traditional therapeutic agents derived from C. Bovis, we felt that several issues needed to be addressed: 1) the source of the C. Bovis materials and quality control; 2) the role of taurine in the efficacy of C. Bovis.MethodsNine samples of natural C. Bovis and its substitutes were collected. ICP-MS was used for elemental analysis and the characterization was performed by principal component analysis (PCA) and soft independent modeling of class analogy (SIMCA) as multivariate approaches. The efficacy of C. Bovis was evaluated for morphology, viability and beating pattern on cultured cardiac myocytes and/or fibroblasts.ResultsPCA and multi-elemental focus was effective in discriminating C. Bovis samples derived from different habitats. A satisfactory classification using SIMCA was obtained among Australia C. Bovis, other habitats and the substitutes. Australian samples had better batch uniformity than other habitats and were composed of fewer elements. We have used Australian C. Bovis for assessment on its bioactive compounds. Rat cardiac cells incubated with C. Bovis extract (0.01-0.1mg/ml) maintained normal morphology, viability and beating pattern. Cardiac myocytes and fibroblasts treated for 48 h with CA (0.5mM) or DCA (0.1mM) caused cell injury, as reflected by changes in appearance and a reduction of viability detected by the MTS assay. In cardiomyocytes, 0.5 h exposure of CA (0.5mM) markedly decreased the velocity ratio of beating, whereas the simultaneous addition of 1 mM taurine largely prevented the decrease.ConclusionsThe multi-elemental focus provided some references for the quality control and the efficacy of C. Bovis. Taurine partly attenuated the harmful actions of bile acids. It is plausible that the relationship between taurine and the bile acids contributes to therapeutic effect of C. Bovis.

As co-research with agricultural chemists, we developed a vegetable geographical origin identification system using difference of trace element compositions of vegetables from cultivated districts. The system works well to identify geographical origin of vegetables in our previous works. However, there are some problems to gather trace element compositions data. Generally, measured trace element data contains outlying observations, and normally an experimenter removes these kinds of outlying observations. However, in case of massive data must be registered in short time, checking of measured data by hand is an obstruction to automatically registration. Therefore, in this paper, we describe about trial to introduce outlying observation detector using Smirnov test. Also, we describe about how to extract measured data in electronic form from measuring instruments such as ICP-MS which are normally closed system.
