Abstract:In order to establish the identified model of jujube origin and provide theoretical basis for the origin traceability of jujube, samples of jujube were originated from Henan Xinzheng, Shanxi Taigu, and Xinjiang Hami, Cele and Yutian. The contents of strontium isotope (87Sr/86Sr) and 33 elements in jujube were determined by thermoelectric ionization mass spectrometer and inductively coupled plasma mass spectrometer. The discriminant analysis of jujube from different producing areas in Xinjiang province, Henan province and Shanxi province was carried out in combination with principal components and discriminant analysis in stoichiometry. Multiple comparison results showed that the Rb content of Xinzheng and Yutian jujube was significantly higher than that of Hami and Cele.The content of Zn in Taigu jujube was significantly higher than that in Yutian. The Sr isotope signatures (87Sr/86Sr) in Cele jujube was highest than that in jujube from other areas, while the 87Sr/86Sr in Xinzheng, Taigu and Yutian was significantly higher than that from Hami. By collinearity diagnosis analysis, the discriminating model of 87Sr/86Sr and seven elements (scandium, vanadium, cobalt, zinc, yttrium, cadmium and cesium) were established.The overall discriminant rate of jujube back substitute test and cross-check test from five areas were 100% and 82.7%, respectively. It might be feasible to distinguish jujube from different areas by 87Sr/86Sr and seven elements combined with stoichiometry.
