To establish a RP-HPLC method for fast and simultaneous determination of four index contents, which are Genpioside, Baicalin, Berberine Hydrochloride and Ammonium Glyeyrrhizinate, in Qingwei Huanglian tablets.
A separation was well achieved by gradient elution on a Hypersil C18 (4.6 mm x 250 mm, 5 microm) column with the mobile phases of acetontrile -0.5% triethylamine water-solution (pH 3.0) at a flow rate of 1.0 mL x min(-1), detection wavelength of 230 nm, and room temperature.
The calibration curve were linear in the ranges of 4.82-77.2, 5.80-92.8, 1.63-26.1 and 6.40-102 microg x mL(-1) (r = 0.9997-0.9999) for genpioside, baicalin, berberine hydrochloride and ammonium glyeyrrhizinate, respectively. The average recoveries of four index components were not less than 98.0%.
The method is convenient, rapid and accurate. It is suitable for the quality control of Qingwei Huanglian tablets.
建立一种反相高效液相色谱法,用于快速同时测定清胃黄连片中的4种指标成分,即栀子苷、黄芩苷、盐酸小檗碱和甘草酸铵。
采用Hypersil C18(4.6 mm×250 mm,5μm)色谱柱,以乙腈-0.5%三乙胺水溶液(pH 3.0)为流动相进行梯度洗脱,流速为1.0 mL·min⁻¹,检测波长为230 nm,柱温为室温,实现了良好的分离。
栀子苷、黄芩苷、盐酸小檗碱和甘草酸铵的校准曲线分别在4.82 - 77.2、5.80 - 92.8、1.63 - 26.1和6.40 - 102μg·mL⁻¹范围内呈线性关系(r = 0.9997 - 0.9999)。4种指标成分的平均回收率均不低于98.0%。
该方法简便、快速、准确,适用于清胃黄连片的质量控制。
