本文报导用硅藻土-乙睛柱的分配层析法从皮质甾类分离氯碘喹啉是一个简便、快速的定量方法。分离后,使氯碘喹啉形成镍络合盐在406毫微米波长处测定其含量,皮质甾类的测定则采用美国药典第18版的蓝四唑法。21种不同的药物处方如霜膏、洗剂、油膏以及混悬剂等均可用这方法进行测定。设备用紫外分光光度计,玻璃层析柱(2.2×15厘米,一端收缩为0.4×5厘米)附铝制压棒。用酸
This paper reports the isolation of chloroiodoquinol from corticosteroids using a diatomaceous earth-ethyl acetate column chromatography as a simple and rapid method of quantification. After isolation, the content of the chloroiodoquinoline nickel complex salt was measured at a wavelength of 406 nm and the corticosteroid was determined using the blue tetrazolium method of the U.S. Pharmacopeia, 18th edition. 21 different kinds of prescription drugs such as creams, lotions, ointments and suspensions can be measured by this method. Equipment with UV spectrophotometer, glass column (2.2 × 15 cm, one end contracted to 0.4 × 5 cm) with aluminum bar. With acid
