复方甲氧沙林洗剂可治疗银屑病、湿疹、白癜风、扁平苔藓等。本文采用高校液相测定了复方甲氧沙林洗剂中醋酸地塞米松和甲氧沙林的含量,固定相为:思普乐C18液相色谱柱(4.6mm×250mm,5μm),甲醇-水(75:25)为流动相,检测波长为240nm;此方法简便、准确、重现性好,可用于复方甲氧沙林洗剂中甲氧沙林和醋酸地塞米松的含量测定。 Compound methoxsalen lotion can treat psoriasis, eczema, vitiligo, lichen planus and so on. In this paper, the content of dexamethasone acetate and methoxsalen in the compound methoxalin lotion was determined by the liquid phase in the university. The stationary phase consisted of Spirulina C18 column (4.6 mm × 250 mm, 5 μm), methanol- Water (75:25) as the mobile phase at a detection wavelength of 240 nm. The method is simple, accurate and reproducible. It can be used for the determination of methoxsalen and dexamethasone acetate in compound methoxsalen.
