目的 建立小儿百部止咳糖浆中苦杏仁苷的测定方法；方法 采用反相高效液相色谱法，色谱柱为Agilent Hypersil ODS， 流动相为甲醇-0.1%磷酸溶液(19∶81)，检测波长210 nm。结果 苦杏仁苷在0.081 6～1.020 μg呈良好的线性关系，平均回收率为98.63%，RSD＝1.15%。结论 本方法简便、准确，重现性好。可作为小儿百部止咳糖浆的质量控制标准。

Objective To establish a method for determination of amygdaloside in Child Baibu Zhike Syrup. Methods RP-HPLC was used with Agilent Hypersil ODS as analytical column. The mobile phase was methanol-0.1% phosphoric acid solution (19:81). The detective wavelength was set at 210 nm. Results The calibration curve was linear in the range of 0.081—1.020 μg for amygdaloside r＝0.999 9). The average recovery was 98.63% (RSD＝1.15%). Conclusion The method is convenient, accurate and reproducible. It can be applied to quality control of amygdaloside in Child Baibu Zhike Syrup.
