Abstract: 目的 建立液相色谱法测定痛舒胶囊中三七皂苷R1及人参皂苷Rg1、Rb1含量.方法 采用Watres Symmetry RP18(4.6 mm×250 mm,5 μm)色谱柱,乙腈-水为流动相,梯度洗脱,体积流量1.0 mL·min-1,检测波长203 nm,柱温30 ℃.结果 三七皂苷R1的线性范围为0.206~3.09 μg(r=0.999 4),平均加样回收率为104.2%,RSD为0.77%(n=9);人参皂苷Rg1的线性范围为0.882~13.23 μg(r=0.999 5),平均加样回收率为100.7%,RSD为1.1%(n=9);人参皂苷Rb1的线性范围为0.921~13.82 μg(r=0.999 2),平均加样回收率为103.1%,RSD为2.1%(n=9).结论 本方法灵敏、准确,重现性好,可用于本制剂的含量测定及质量控制.
