EVALUATION OF MITODEPRESSIVE EFFECT OF SUNSET YELLOW USING Allium sativum ASSAY
نویسنده
چکیده
The influence of a permitted yellow food colour, Sunset yellow –FCF on root tips of Allium sativum was investigated with a view to ascertaining its mitodepressive effect. Root tips of Allium sativum were treated with five concentrations of Sunset yellow like 100 ppm,250 ppm,500 ppm,750 ppm and 1000 ppm and with distilled water as control. The time of action of the respective concentration of solutions were 2 hrs,4 hrs and 6 hrs. Exposure to different concentrations of Sunset yellow showed an inhibitory effect on cell division of Allium sativum root tips. It caused a general decline in mitotic index value. Sunset yellow diminishes the mitotic index in correlation with the increased concentration and duration of treatment. The results implicated Sunset yellow – FCF as a mitotic depressor.
