Abstract:

In order to systematically study enrichment and absorption rules of Lycium barbarum, and promote the safety production, an atomic fluorescence method has been developed for quantitative analysis. Using Lycium barbarum variety ‘Ningqi No.1’ as the material, spraying sodium selenite through leaf, selenium-rich Lycium barbarum was formed by absorption and transformation. The results showed that: 7 Se concentrations in the 0.1-200.0 mg/kg between the Lycium barbarum selenium content significantly increased, taking Lycium barbarum fruit was affected for selenium analysis, the selenium content between the 0.17-3.34 mg/kg, and the linear relationship was obtained in this method (r=0.9992). Spray concentration, the number were the key factors of production of selenium-rich Lycium barbarum by application of sodium selenite. Drying process was no significant effect on the selenium content in Lycium barbarum.
