HPLC法测定太子参黄芪口服液中太子参环肽B的含量

目的：建立太子参黄芪口服液中太子参环肽B含量测定的HPLC方法。方法采用Phenomenex Luna-C18柱(4.6 mm×250 mm，5μm)，以乙腈-0.1%醋酸溶液为流动相，梯度洗脱，流速1.0 ml/min，柱温30℃，检测波长203 nm。结果太子参环肽B在0.016～0.320 mg/ml浓度范围内有良好线性关系(r＝0.9998)，平均加样回收率为98.92%，RSD为0.80%。检测5批太子参黄芪口服液中太子参环肽B的平均含量为1.63 mg/ml。结论本方法灵敏度高、准确、重复性好、专属性强，可用于太子参黄芪口服液的质量控制。

Determination of heterophyllin B inTaizishen-Huangqi oral solution by HPLC

Objective To study a method for the determination of heterophyllin B inTaizishen- Huangqi oral solution.Methods The HPLC system consisted of Phenomenex Luna-C18 (4.6 mm × 250 mm, 5μm) column, the mobile phase consisted of acetonitrile and 0.1% acetic acid, the gradient elution flow rate was 1.0 ml/min, the column temperature was 30℃, and the UV detector was set at 203 nm.Results The linear response range was 0.016-0.320 mg/ml (r=0.999 8). The average recovery of heterophyllin B was 98.92%, and RSD was 0.80%. The average determination of Heterophyllin B within 5 batches of preparation was 1.63 mg/ml. Conclusions The method showed its high sensitivity, accurate, repeatable and high secificity. It could be used as a method to control the standard ofTaizishen-Huangqi oral solution.
