Fluorinmetric Determination of Aloe-emodin in Samples
QI Deng-fu (Shandong University of Technology, Zibo 255091, China)
The optimal conditions of aloe-emodin determination were studied by fluorimetric analysis. Based on the conditions of λex/em=470/545nm and pH=7.0, the linear range of calibration curve is 3.7×10 -6 ～3.0×10 -5 . The detection limit is 31ppb and the relative deviation is 2.18%.This developed method is successfully applied to the determination of aloe-emodin in samples of cassi toral,Serum and urine.The results are satisfying.
