摘 要:采用高效液相色谱法测定连蒲双清片中咖啡酸及盐酸小檗碱含量。色谱柱为Diamonsil C18,流动相A:乙腈,B:0.5%三乙胺水溶液(用磷酸调PH值为3.14)[0~13min(A∶B=12∶88),13~35min(A∶B=25∶75)],流速:1.0mL·min-1,检测波长320nm,进样量:10μL。盐酸小檗碱在148~740μg(r=0.9996)、咖啡酸在1~20μg(r=0.9995)范围内具有良好的线性关系,平均回收率分别为99.64%(RSD=0.81%)、99.45%(RSD=1.18%)。本方法准确可靠,简单易行,可用于连蒲双清片的含量测定。Use HPLC method measurement Lianpu Shuangqing Pian double caffeic acid and berberine hydrochlcride content. The assay was performed on Diamonsil C18 with flow gradient A. acetonitrile, B: 0. 5% chemical reacent (adjust pH to be worth to 3.14 with the phosphoric acid) 0-13min (12%A+88% B) 13-35min (25%A+75%B) current velocity: 1.0mL % min-I , the examination wave-length is 320 nm. Berberine hydrochlcride was sour in 148%740 %g, caffeic acid at 1-20 μg had the good line form relation (r=0. 9997, r=0. 9996), the average recovery rate distinguished to 99.64%, 99.45%. This method is accurate, reliable, simple and feasible. It can be used for the determination of caffeic acid and berberine hydrochlcride in Lianpu Shuangqing Pian.
