摘要:目的 建立HPLC波长切换法测定银花芒果片中芒果苷、橙皮苷含量的方法。方法 采用Agilent ZORBAX Eclipse XDB-C18(4.6 mm×150 mm,5 ?m)色谱柱,流动相为甲醇-0.2%磷酸水溶液,梯度洗脱,流速为1.0 mL/min,柱温30 ℃,波长切换时间序列采样(0~20 min为258 nm,20~50 min为283 nm)。结果 芒果苷进样量在0.042~0.761 ?g 范围内线性关系良好(r=0.999 9),平均回收率为99.86%,RSD=1.5%(n=9);橙皮苷进样量在0.076~1.361 ?g范围内线性关系良好(r=0.999 8),平均回收率为99.91%,RSD=0.7%(n=9)。结论 本方法简便、快捷、准确,可用于该制剂的质量控制。

Abstract: Objective To establish an HPLC method of wavelength switching simultaneous determination for the contents of mangiferin and hesperidin in Yinhua Mangguo Tablets. Methods Agilent ZORBAX Eclipse XDB-C18 (4.6 mm×150 mm, 5 ?m) column was used. The mobile phase was methanol-water containing 0.2% phosphoric acid with gradient elution mode at the flow rate of 1.0 mL/min; the detection wavelength was 258 nm (0–20 min) for mangiferin, 283 nm (20–50 min) for hesperidin. Results Mangiferin had a good linearity in the range of 0.042–0.761 ?g, and the average recovery was 99.86%, with RSD of 1.5% (n=9). Hesperidin had a good linearity in the range of 0.076–1.361 ?g, and the average recovery was 99.91%, with RSD of 0.7% (n=9). Conclusion The method is simple, accurate and reproducible, which can be used to the quality control of Yinhua Mangguo Tablets.

银花芒果片是由芒果叶、陈皮、蒲公英、桔梗、金银花、百部、甘草等制成的中药成方制剂,有疏风清热、止咳化痰的功效,临床用于外感风热所致的咽痛、喉痒、咳嗽、上呼吸道感染、急性支气管炎等症,收载于《国家中成药标准汇编内科肺系(二)分册》。现行质量标准为测定陈皮中的橙皮苷含量,但对处方中另一味主要药物芒果叶只有薄层鉴别实验,未进行定量测定,难以有效全面地反映制剂的质量。芒果叶具有止咳化痰的功效,芒果苷是其中的主要活性成分[1]。本试验选择芒果苷和橙皮苷为质量控制指标,采用HPLC波长切换法测定银花芒果片中芒果苷和橙皮苷的含量。
