疾肤康软膏是卫生部批准生产的新药。为控制药品质量,采用薄层层析法和紫外光谱法,对处方中主要成分进行定性试验。用紫外分光光度法在269±1nm波长处对其主要成分十八碳三烯酸的含量进行测定。实验表明,该方法简便,结果准确。
Gufukang ointment is a new drug approved by the Ministry of Health. In order to control the quality of medicines, the main components of the prescriptions were qualitatively tested by thin layer chromatography and ultraviolet spectroscopy. The content of octadecatrienoic acid, its main component, was determined by ultraviolet spectrophotometry at a wavelength of 269±1 nm. Experiments show that this method is simple and accurate.
