Abstract:ObjectiveTo establish a HPLC method for the determination of Hyperoside in Compound luobuma tablets I.MethodsThe HPLC method was used with a mixture of accetonitrile-0. 2% phosphate(15∶75)as the mobile phase.The determination wavelength was set at 256nm with the flow rate of 1. 0ml/min.ResultsThere was a good linearrelationship between the sample volume and the peak area in the range of 35. 6μg~71. 2μg(r =0. 999).The average recovery rate was 98. 93%,RSD =1. 98%(n =6).ConclusionsThe method is stable and accurate.It can be used for the content determination of Hyperoside in Compound luobuma tablets I.

复方罗布麻片Ⅰ收载于《化学药品地方标准上升国家标准(第十一册)》,由罗布麻叶、野菊花、防己、硫酸双肼嗪等组成,为中西药复方制剂.方中罗布麻叶具有平肝安神、清热利水之功,对本方发挥临床疗效有重要作用.原标准中未对罗布麻叶进行质量控制.现代药理研究表明,罗布麻叶降血压、降血脂主要活性成分为黄酮类化合物,其中以金丝桃苷含量最高[1].为有效控制复方罗布麻片Ⅰ的质量,促进临床用药安全,本试验建立了以反相高效液相色谱法测定复方罗布麻片Ⅰ中金丝桃苷含量的方法.
