摘　　要：采用高效液相色谱法对银杏内酯A进行测定含量和检查有关物质专属性研究。能有效检查有关物质,最低检出量为0.03μg。在0.1～0.5mg/ml范围内,银杏内酯A浓度与峰面积有良好的线性关系(r=0.9998);平均回收率为99.9%,RSD为0.15%。本方法准确、灵敏、结果可信,专属性良好。To develop the specificity for ginkgolide A(GA). HPLC was used to determine ginkgolide A content and test its related compounds. The method can test related compounds with a detection limit of 0.03μg. There is a good linearity in the range of 0.1～0.5mg/ml of ginkgolide A. The average recovery was 99.9% and RSD was 0.15% respectively. The method is repeatable,accurate and highly specific.
