摘  要:目的:用高效液相色谱(HPLC)法测定环孢素乳膏剂中环孢素的含量。方法:色谱柱为VP-ODS C18柱(4.6mm×150mm,5μm);流动相为乙腈-水-磷酸(760:240:0.5,v/v);流速为1mL·min^-1;检测波长为210nm;柱温为60℃。结果:环孢素在20-400mg·L^-1范围内线性关系良好(r=0.9996),高、中、低浓度回收率(n=3)分别为98.6%(RSD为0.95%)、99.0%(RSD为0.82%)和99.2%(RSD为0.57%)。结论:该方法灵敏度高.线性范围广,具有较高的专属性,快速简便,重现性好,适合于该制剂的含量测定和质量控制。OBJECTIVE To establish an HPLC method for determination of the content of cyclosporin in its cream. METHODS The HPLC system consisted of C18 column(4. 6 mm× 150 mm, 5μm) with acetonitrile-water-phosphate (760:240:0. 5, v/v) as mobile phase, detection at 210nm, the flow rate was 1.0 mL,min-1 and column temperature at 60 ℃. RESULTS The linear range was 20 - 400 mg. L^- 1 (r = 0. 999 6). The recovery (71 = 3) was 98. 6% at a higher concentration (with RSD of (1. 95%), 99. (1%/40 at middle concentration (with RSD of 0. 82%) and 99. 2% at a lower concentration (with RSD of 0. 57%). CONCLUSION The method is found to be simple, quick, accurate and suitable for determination of content of cyclosporin cream.
