本文采用薄层扫描法对中成药小儿奇应丸中的盐酸奎宁含量测定作了探讨。以氯仿一醋酸乙酯—二乙胺(6∶3∶1)为展开削,用岛津CS—930双波长薄层扫描仪扫描测定,仪器参数:反射法,锯齿扫描,λ_R=360nm,λ_S=325nm,SX=3。盐酸奎宁在1～11μg范围内线性关系良好,回收率为100.8%,方法简便、灵敏、准确。 In this paper, thin layer scanning method for determination of quinine hydrochloride content of Chinese medicine pediatric Qi Ying pill was discussed. Using chloroform-ethyl acetate-diethyl amine (6: 3: 1) as a starting point, the samples were measured with Shimadzu CS-930 dual-wavelength thin layer scanner. The parameters of the instrument were: reflection method, sawtooth scanning, λR = 360nm, = 325 nm, SX = 3. Quinine hydrochloride in the range of 1 ~ 11μg good linearity, recovery was 100.8%, the method is simple, sensitive and accurate.
