STUDY ON THE PROTECTIVE EFFECT OF SINAPINE AGAINST RADIATION TO DROSOPHILA / 营养学报

Objective To investigate the antiradiation effect of sinapine in Drosophita. Method Sinapine in cauliflower was quantified by HPLC, and added in Drosophila culture substrate. We observed the effect of sinapine from cauliflower on reproductive rate, sex ratio, mutation rate of Drosophila after UV radiation. Results Sinapine in cauliflower contained 4.429 ?g/ml thiocyanate. After adding sinapine thiocyanate 0.29075 mg/ml to the media,the reproductive rate of UV irradiated Drosophila culture increased 27.083%, the sex ratio (female/male) and mutation rate declined 23.457% and 97.202% respectively, and the growth cycle became normal again. Conclusion Cauliflower’s sinapine thiocynate has quite favorable anti-radiation function.
