本文采用双波长薄层扫描法,以氯仿—甲醇—水(65:35:10)下层为展开剂,2%茚三酮试剂作显色剂,经薄层扫描测定了鼻出血处理剂中麻黄素的含量,结果平均回收率101.4%变异系数3.05%。盐酸丁卡因可直接用紫外分光光度法在310±1nm 泼长处测定含量,麻黄素及其他附加剂在此波长下对丁卡因的影响小于1%,回收率为100.6%,变异系数0.93%。 In this paper, double-wavelength thin-layer scanning method was used, the lower layer of chloroform-methanol-water (65:35:10) as developing solvent, 2% ninhydrin reagent as the color reagent, The results showed that the average recovery rate was 101.4% and the coefficient of variation was 3.05%. Tetracaine hydrochloride may be directly measured by UV spectrophotometry at a concentration of 310 ± 1 nm sparging, ephedrine and other additives at this wavelength tetracaine less than 1%, the recovery rate was 100.6%, the coefficient of variation of 0.93% .
