HPLC法同时测定有柄石韦中6种有效成分的含量

建立了高效液相色谱法同时测定有柄石韦中原儿茶酸、绿原酸、香草酸、咖啡酸、芒果苷以及芦丁6个主要成分含量的方法。采用Sino Chrom ODS-BP C18(4.6 mm×150 mm,5μm)色谱柱,以质量分数0.1%磷酸(A)-乙腈(B)为流动相进行梯度洗脱,流速1.0 m L/min,检测波长320 nm,柱温25℃。结果表明,6种成分线性关系良好(R≥0.999 2,n=5),且分离度较好,平均加样回收率相对标准偏差均小于5%。该方法快速、简便、准确,为药用植物有柄石韦的定量检测和质量控制提供了实验依据。

Simultaneous determination of six active constituentsin the Pyrrosia petiolosa (Christ) Ching by HPLC

A HPLC method for simultaneous determination of the contents of six main bioactive constituents (protocatechuic acid, chlorogenic acid, vanillic acid, caffeic acid, mangiferin, and rutin) in the Pyrrosia petiolosa (Christ) Ching was presented. The analysis was performed on SinoChrom ODS-BP C18（4.6 mm × 150 mm，5 μm）column. The six components were separated with gradient elution using mobile phase composed of 0.1% acetic acid (A) acetonitrile (B) at a flow rate of 1.0 mL/min. The UV detection wavelength was set at 320 nm. The column temperature was kept at 25℃. Six ingredients showed good linear relationship (R≥0.999 2, n=5), with relative standard deviation values less than 5%. Results reveal that this method is rapid, simple, and accurate, to provide experimental foundation for the quantitative detection and quality control of Medical Pyrrosia petiolosa (Christ) Ching.
