本文报道二阶导数光谱法可迅速测定滴眼液中后马托品的含量。本法制备样品简便,制成稀释液即可测定。此法尚可测定硫酸阿托品滴眼液的含量。仪器 Shimadzm UV～265FW分光光度计,条件设置如下:导数模式:二阶;波长范围240～290 nm;光度范围+0.1～-0.1;△λ2nm;扫描速度慢(每分钟50nm),横坐标刻度10nm/cm。制剂和标准品氢溴酸后马托品滴眼液1.0和2.0％(w/v),硫酸阿托品滴眼液0.5和1.0％,均按BPC(1973年)配制。
This article reports the second derivative spectrometry rapid determination of horsutail eye drops content. The method of preparing samples is simple and can be determined by dilution. This method can be determined atropine sulfate eye drops content. The instrument Shimadzm UV ~ 265FW spectrophotometer, the conditions are set as follows: Derivative mode: second order; wavelength range of 240 ~ 290 nm; Luminosity range +0.1 ~ -0.1; △ λ2nm; Scanning speed (50nm per minute), abscissa scale 10nm / cm. Formulations and Standards 1.0 and 2.0% (w / v) of atropine hydrobromide eye drops and 0.5 and 1.0% of atropine sulfate eye drops were formulated according to BPC (1973).
