【Abstract】 In this paper,different conditions for the determination of nilestriol with fluorescent spectrometry were investigated.It was found that β-cyclodextrin could enhance the fluorescence intensity greatly under neutral situation,thus a simple and highly sensitive approach was put forward with the linear range of 2.63×10^-7～1.84×10^-5 mol/L and the detection limit of 9.4×10^-8 mol/L,which has been successfully applied to the determination of nilestriol in tablets.The results were satisfactory.更多还原
