| 摘要: |
| 为完善麻杏石甘颗粒质量标准，采用高液相色谱法对麻杏石甘颗粒中盐酸麻黄碱的含量测定进行了研究。采用Thermo scientific BDS C18色谱柱（4.6 mm×250 mm，5 μm），流动相为乙腈-0.1%磷酸溶液（含0.1%三乙胺）（3:97），检测波长207 nm，流速1.0 mL/min，柱温30℃，进样量10 μL。结果表明，盐酸麻黄碱进样浓度在5～60 μg/mL范围内，峰面积与盐酸麻黄碱含量呈良好线性关系（R2= 0.9999）。样品平均回收率为96.62%（n=6），RSD为1.30%。本方法简便、准确度高、重复性好、耐用性强，为进一步提高该制剂的质量标准，保证临床效果，提供了检测依据。 |

| Abstract: |
| In order to improve the quality standard of Maxingshigan granules, the content of ephedrine hydrochloride in Maxingshigan granules was determined by high liquid chromatography.Thermo scientific BDS C18 column (4.6 mm×250 mm, 5 μm) was used, the mobile phase was acetonitrile-0.1% phosphoric acid solution (containing 0.1% triethylamine) (3:97), the detection wavelength was 207 nm, the flow rate was 1.0 mL/min, the column temperature was 30℃, and the sample volume was 10 μL.The results showed that the injection concentration of ephedrine hydrochloride was within 5～60 μg/mL, the peak area had a good linear relationship with the content of ephedrine hydrochloride (R2=0.9999).The average recovery was 96.62%(n=6), and the RSD was 1.30%. This method is simple, accurate repeatable, and strong durability, which provides a basis for further controlling the quality standard of Maxingshigan granules. |
