本文基于首乌片中的二苯乙烯甙径Dans-Cl试剂衍生化后,具有强烈的荧光特性,提供了在醋酸乙酯递质中的荧光分光光度测定方法。激发波长338nm,发射波长510nm。二苯乙烯甙溶液浓度在1.0×10~(-7)～5.0×10~(-7)g/ml范围内衍生化后与荧光强度呈线性关系。溶液的荧光强度在2hr内稳定。文内拟定的测定条件与紫外分光光度法测得的结果基本一致。 In this paper, based on the stilbene quinone Dias-Cl reagent derived from Shouwu tablets, it has strong fluorescence characteristics and provides a fluorescence spectrophotometric method for determination of ethyl acetate in the transmitter. Excitation wavelength 338nm, emission wavelength 510nm. When the concentration of stilbene solution was derivatized in the range of 1.0×10 -7 to 5.0×10 -7 g/ml, the fluorescence intensity was linear. The fluorescence intensity of the solution is stable within 2 hr. The experimental conditions developed in this paper are basically consistent with those obtained by UV spectrophotometry.
