摘 要：
本试验建立了鱼腥草、柴胡、维生素C、盐酸林可霉素、黄芪多糖等注射液中非法添加地塞米松磷酸钠的超高效液相色谱检查方法。采用Waters ACQUITY UPLC?BEH C18色谱柱(2.1mm×50mm,1.7μm),以0.75%三乙胺溶液(磷酸调节pH 3.0)-甲醇-乙腈(50∶45∶5)为流动相,流速0.3mL/min,二极管阵列检测器,波长采集范围为190~400nm,记录色谱图波长242nm,柱温25℃,进样量10μL。地塞米松磷酸钠质量浓度在10.0~200.0mg/L内峰面积呈良好线性关系(R2=0.9999),在鱼腥草、柴胡、维生素C、盐酸林可霉素、黄芪多糖等注射液中地塞米松磷酸钠的平均回收率和相对标准偏差(RSD)分别为97.54%和1.14%、101.59%和0.19%、100.92%和0.92%、99.82%和0.73%、100.08%和0.62%。本方法简单、快速、灵敏、可靠,适用于鱼腥草等5种注射液中非法添加地塞米松磷钠的检查。

摘 要：
A detection method of dexamethasone sodium phosphate in houttuynia injection,bupleurum injection,vitamin C injection,lincomycin hydrochloride injection,and asragulus polysacharin injection was established by UPLC-PDA.The Waters ACQUITY UPLC?BEH C18column(2.1mm×50mm,1.7μm)was used,the mobile phase consisted of 0.75% triethylamine phosphatic liquor/solution(pH 3.0)-methyl alcohol-acetonitrile(50∶45∶5),the flow rate was0.3mL/min,the column temperature had remained 25 ℃,photodiode array detector wavelength range was 190 to 400nm,the recorded wavelength was 242 nm,the injection volume was 10μL.The linear range of dexamethasone sodium phosphatel was 10.0to 200.0mg/L(R2=0.9999),the mean recovery and RSD for dexamethasone sodium phosphate in houttuynia injection,bupleurum injection,vitamin C injection,lincomycin hydrochloride injection and asragulus polysacharin injection were 97.54 % and 1.14%,101.59% and 0.19%,100.92% and 0.92%,99.82% and0.73%,100.08% and 0.62%,respectively.This method was accurate,easy and fast,it was suitable for detection of dexamethasone sodium phosphatein houttuynia injection and other four kinds of injections.
