Abstract: For the reason that:some agricultural products which have higher economic value were often simulated by the counterfeiters.It was in urgent need of building theirs source database to insure the safety of agricultural products in order to clear the change laws of stable nitrogen isotope in tissue of Chinese-date,and the effect of such factors as breed,region,and sampling time on δ15N values of in tissue of Chinese-date,as well as to screen the sampling location of Chinese-date in origin traceability,it was measured in this paper δ15N values in tissue of fructus corni,jujube meat,jujube pit as the research object to Zanhuang jujube and jujube in Tai-hang Mountain main producing areas such as Zanhuang Country,Xingtang Country,Fuping Country.The results showed that:Under the comprehensive influence of such factors as breed,region,sampling time and year,the difference of δ15N value sexsited between breeds of Zanhuang jujube and jujube,Zanhuang jujube was higher than that of jujube;And the change law of the two breeds was different:For Zanhuang jujube,jujube pit >jujube meat(P>0.05) >frctus corni(P>0.05),For jujube:jujube meat>frctus corni(P>0.05)>jujube pit(P<0.05).For the reason that the value of δ15N had no significant difference in jujube meat between two breeds,it was suggested that we should take jujube meat as sampling location in origin traceability of Chinese-date.The effects of breed,region,and sampling time on δ15N of jujub meat was co-operational.

Key words: Chinese-date, Traceability, Stable isotope, δ15N
