【Abstract】 Objective: A method was established for the determination of isorhamnetine and quercetin in flavone hippophaes tablets by HPLC.Methods:The HPLC system consisted of Diamonsil C18 column (250 mm×4.6 mm, 5μm), mobile phase of methanol-0.02mol/L phosphoric acid (54:46) .column temperature at 40℃,with detection at 368 nm. Results:The linear range of isorhamnetine and quercetin were 6.5-32μg/ml (r = 0.9996) and 2.5-12.4 μg/ml (r= 0.9991).The average recoveries were 99.4% and 99.8%,respectively.The wit... 更多还原 【关键词】 醋柳黄酮片; 异鼠李素; 槲皮素; 高效液相色谱法; 【Key words】 Flavone hippophaes tablets; Isorhamnetine; Quercetin; HPLC;
