摘要：

The influence of Gamma irradiation on content of some important flavonoids (flavonones glycosides and polymethoxylated flavones) was evaluated during storage of Moroccan clementina treated at a mean dose of 0.3 kGy and stored three months at 3'C. Results shows that at day one, gamma irradiation induced degradation of small quantities of these flavonoids, however after 14 days of storage, the content of these compounds was significantly higher (p less than or equal to 0.05) in irradiated samples. Irradiation stimulated biosynthesis of flavonoids after 14 days of storage. Hesperidin was the major flavanones compounds in clementines. Nobiletin and Heptamethoxyflavone were the major polymethoxylated flavones in clementines. Our study demonstrated that the content of these compounds was significantly higher (p less than or equal to 0.05) in irradiated samples.
