Abstract
目的:建立高效液相色谱(HPLC)法同时测定虎力散片中三七皂苷R1、人参皂苷Rg1和Rb1的含量.方法:采用CAPCELL PAK C18色谱柱(250 mm×4.6 mm,5μm),流动相A为乙腈,流动相B为水,梯度洗脱,流速为1.0 mL/min;柱温30℃,检测波长203 nm.结果:三七皂苷R1、人参皂苷Rg1和Rb1线性范围分别为0.095~1.428μg(r=0.9999)、0.326~4.896μg(r=1.0000)、0.307~4.611μg(r=0.9999);平均加样回收率分别为98.16%(RSD=1.07%)、99.58%(RSD=0.44%)、99.73%(RSD=0.47%).结论:该方法结果准确、精密度和重复性好,可用于虎力散片的质量控制.
