摘  要:目的建立测定心脑肾康胶囊的反相高效液相色谱法。方法采用芬兰产C18柱(Φ5μm,4.6×150mm),0.04mol·L^-1枸橼酸-N,N-二甲基甲酰胺-四氢呋喃(55:8:2)为流动相,流速:1.0mL·min^-1,检测波长:280nm,柱温:35℃,峰面积外标法定量。结果表没食子儿茶素没食子酸酯(EGCG)在0.24~1.44μg范围内线性关系良好(r=0.9998,n=6),平均回收率为(100.63±1.88%,n=5),RSD日内0.48%,RSD日间1.87%。结论本法简便、灵敏、重现性好,适合心脑肾康胶囊的含量测定和质量控制。OBJECTIVE To establish a simple method for the determination of the content of epigalloeatechin gaUate(EGCG) in Xinnan Sbenkang (XNSK) by RP-HPLC. METHODS Used C18 chromatographic column( Φ5μm,4.6 × 150mm) ,0.04mol · L^-1 citric acid- N,N- dimethylformarnide- THF (55: 8: 2) as mobile phase,and the detector wavelength was at 302nm. The EGCG content was determined with peak area by external reference method. RESULTS The line arrange was from 0.24 to 1.44μg (r =0.999 8). The average recovery was( 100.63± 1.88) % , The RSD of within-day was 0.48% , and that of between-day was 1.87% . The detection limit was 0.012μg·mL^-1. CONCLUSION The method is simple, sensitive, and feasible for the determination of EGCG content and quality control of XNSK.
