HPLC法同时测定脑脉泰胶囊中12种成分的含量OA北大核心CSTPCD
Simultaneous content determination of twelve constituents in Naomaitai Capsules by HPLC
目的 建立HPLC法同时测定脑脉泰胶囊中 3′-羟基葛根素、2-羟基红花黄色素A、葛根素、葛根素芹菜糖苷、3′-甲氧基葛根素、大豆苷、二苯乙烯苷、木犀草苷、染料木苷、木犀草素、丹酚酸B、迷迭香酸的含量.方法 分析采用Kromasil C18 色谱柱(250 mm×4.6 mm,5 μm);流动相乙腈-水(含 1.0 g/L 磷酸),梯度洗脱;体积流量0.8 mL/min;柱温 30℃;检测波长 280 nm.再进行聚类分析、主成分分析.结果 12 种成分在各自范围内线性关系良好(r＞0.999 0),平均加样回收率 97.07%～98.30%,RSD 0.86%～1.82%.10 批样品聚为 4 类,4 种主成分累积方差贡献率达 86.262%.结论 该方法简便稳定,可靠准确,可为脑脉泰胶囊的质量控制提供科学依据.
AIM To establish an HPLC method for the simultaneous content determination of 3′-hydroxy-puerarin,hydroxysafflor yellow A,puerarin,puerarin apigenin,3′-methoxypuerarin,daidzein,stilbene glycoside,luteolin side,genistein side,luteolin B and rosmarinic acid in Naomaitai Capsules.METHODS The analysis was performed on a 30℃ thermostatic Kromasil C18 column(250 mm×4.6 mm,5 μm),with the mobile phase comprising of acetonitrile-water(containing 1.0 g/L phosphoric acid)flowing at 0.8 mL/min in a gradient elution manner,and the detection wavelength was set at 280 nm.Subsequently,principal component analysis and cluster analysis were made.RESULTS Twelve components showed good linear relationships within their own ranges(r＞0.999 0),whose average recoveries were 97.00%-99.00% with the RSDs of 0.86%-1.82% .Ten batches of samples were clustered into four categories,the accumulative variance contribution rate of four principal components reached 86.262% .CONCLUSION This simple,stable,reliable and accurate method can be used for the quality control of Naomaitai Capsules.
