摘 要:目的建立复方苦参注射液中氧化槐果碱、氧化苦参碱和苦参碱的含量测定方法。方法Hypersil ODS2色谱柱(200mm×4.6mm,5μm),流动相为甲醇-乙腈-水-磷酸(体积比为10.00:30.00:65.00:0.05.含33mmo·L^-1的SDS)。检测波长为210nm,柱温为室温。结果氧化槐果碱质量浓度在2.52~50.4mg·L^-1内与峰面积呈良好线性关系,r=0.9999(n=6),平均回收率为98.2%。RSD为1.8%(n=9);氧化苦参碱质量浓度在17.44-174.4mg·L^-1内与峰面积呈良好线性关系。r=0.9997(n=6),平均回收率为99.5%,RSD为2.2%(n=9);苦参碱质量浓度在1.96~39.20mg·L^-1内与峰面积呈良好线性关系,r=0.9997(n=6),平均回收率为102.3%,RSD为2.0%(n=9)。结论测定方法可作为复方苦参注射液质量控制方法。Objective To establish a RP-HPLC method for simultaneous determination of oxysophocarpine, oxymatrine and matrine in compound kushen injection. Methods The column of Hypersil ODS2(4.6 mm × 200 mm, 5 μm) was used, the mobile phase was methanol-acetonitrile-water-phosphoric acid( V: V: V: V = 10:30:65:0.05, 33 mmol· L^-1 SDS), the detection wavelength was set at 210 nm and the column tem- perature was 25℃. Results The linear range of oxysophocarpine was 2.52-50.4 mg· L^-1, oxymatrine was 17.44-174.4 mg· L^-1 and matrine was 1.96-39.20 mg· L^-1 respectively. The average recoveries of oxysophocarpine, oxymatrine and matrine were 98.2 % with RSD 1.8 %, 99.5 % with RSD 2.2 % and 102.3 % with RSD 2.0 % ( n = 9). Conclusions The method is accurate, sensitive and suitable for the quality control of compound kushen injection.
