【摘要】:目的:建立HPLC同时测定鸡血藤中原儿茶酸、儿茶素、表儿茶素、甘草素、芒柄花素、美迪紫檀素含量的方法,为鸡血藤药材质量标准改进提供参考。方法:采用ZORBAX SB-C18色谱柱(4.6 mm×150 mm,5μm),以乙腈(A)-0.2%磷酸(B)为流动相进行梯度洗脱,流速1 m L·min~(-1),检测波长为260 nm(检测原儿茶酸、芒柄花素)和280 nm(检测儿茶素、表儿茶素、甘草素、美迪紫檀素),柱温30℃。结果:原儿茶酸、儿茶素、表儿茶素、甘草素、芒柄花素、美迪紫檀素的质量浓度分别在2.286~228.6μg·m L~(-1)(r=0.999 9)、2.174~217.4μg·m L~(-1)(r=0.999 9)、2.79~279μg·m L~(-1)(r=0.999 9)、0.424~42.4μg·m L~(-1)(r=0.999 9)、2.426~242.6μg·m L~(-1)(r=0.999 9)、0.339~33.92μg·m L~(-1)(r=0.999 8)的范围内线性关系良好,加样回收率分别为99.8%(RSD=1.0%)、99.8%(RSD=2.5%)、101.2%(RSD=2.3%)、100.8%(RSD=1.8%)、100.9%(RSD=2.3%)、100.6%(RSD=2.4%)。11批药材中原儿茶酸、儿茶素、表儿茶素、甘草素、芒柄花素、美迪紫檀素含量范围分别为0.250~0.898、1.447~5.662、1.759~11.925、0.035~0.134、0.218~0.535、0.065~0.585 mg·g~(-1)。结论:该方法可用于同时测定鸡血藤中6个黄酮类成分的含量,为该药材的质量标准改进提供参考。
[Abstract]:Objective: to establish a HPLC method for the simultaneous determination of protocatechuic acid, catechin, epigallocatechin, glycyrrhizin, amaranthylin in chicken blood vine, and to provide reference for the improvement of quality standard. Methods: a ZORBAX SB-C18 column (4.6 mm 脳 150 mm,5 渭 m),) with acetonitrile (A) 0.2% phosphoric acid (B) as mobile phase was used for gradient elution with a flow rate of 1 mL min~ (-1) and a detection wavelength of 260 nm (for protocatechuic acid). The column temperature was 30 鈩,
