Abstract: The toxic experiment of Fuzhuan tea was carried out by using the extracted instant Fuzhuan tea as material in order to evaluate its safety for the mice and rat. The results showed that the LD50 of male mice and female mice was 14β700βmg/kg·bw and 19β600βmg/kg·bw respectively(the limit reliability was 10β600~36β000), and both of the Ames test and the semen teratogenicity results were negative. During the 30 days fed by the feeding mixed with 0.85%, 1.25%, 1.70% instant Fuzhuan Tea for the rat rats of each dose group grew well, the hemogram indexes of rats from each dosage, blood biochemical indexes and triglyceride, Urea anhydride, blood muscle anhydride and blood sugar indexes, ratio of spleen to body weight, kidney to body weight, and the histopathological characteristic of all test rats showed no significantly difference (P<0.05), which suggested Fuzhuan Tea was a no poisonous food.
