摘要
目的建立反相高效液相色谱法测定羟苯磺酸钙分散片中的有关物质。方法色谱柱为Hypersil C6H5柱,流动相:0.5 mol.L-1磷酸二氢钠溶液-甲醇-三乙胺(100∶5∶0.02);流速为1.0 ml.min-1;测定波长为301 nm。结果不仅能够测定原料中杂质对苯二酚,还能够与破坏性试验产生的降解产物有效分离。结论该法简便、准确、结果可靠。
AIM To develop a RP-HPLC method for the determination of related substances and degradation subtances of calcium dobsilate.METHODS Chromatographic conditions were as follows： Column： Hypersil C6H5, the mobile phase was composed of 0.5 mol· L^- 1 NaH2PO3 buffer-methanol-cyclo hexyl amine（100 ： 5 ： 0.02） with the flow rate of 1.0 ml· min^- 1, the detective wavelength： 289 nm. RESULTS The impurity and degradation products were detenninged. CONCLUSION The method is convenient,accurate and the results is reliabel.
