目的 HPLC法测定追风搜骨宁丸中马钱子碱和士的宁含量。方法采用HPLC法,以光电二极管阵列检测器(PDAD),色谱柱CAPCELL PAK MG C18(4.6mm×250mm 5(m),马钱子碱、士的宁[含量测定]项下流动相为乙腈-0.01mol/l辛烷磺酸钠与0.02mol/l磷酸二氢钾等量的混合溶液(用10%磷酸调节ph值2.8)(23;77),流速1.0ml/min,检测波长为260nm,柱温30℃,对制剂中马钱子碱、士的宁进行定量测定。结果 HPLC法测定马钱子碱在0.0229~0.172μg范围内均呈良好的线性关系,r=0.9991,加样回收率为96.65%,RSD=0.94%;HPLC法测定士的宁在0.0423~0.317μg范围内均呈良好的线性关系,r=0.9998,加样回收率为97.81%,RSD=2.88%。结论该方法操作简便、专属性、重现性好,可有效地测定追风搜骨宁丸中马钱子碱和士的宁的含量。
Objective To determine the content of brucine and strychnine in Zhuifeng Souguning Pills by HPLC .Methods The content of hydroxyl safflower Brucine and Strychnine was determined by HPLC ,which was conducted with a PDAD detecter and the detection wavelength set at 260nm.The column was CAPCELL PAK MG)C18(4.6mm ×250mm,5(m)with mobile phase consisted of acetonitrile-Octane sulfonate with 0.02mol/l potassium dihydrogen phosphate mixed solution of equal (with 10%phosphoric acid to adjust the ph 2.8)(23∶77)and the flow rate was 1.0ml/min.The column temperature maintained at 30℃.Results HPLC determined that hydroxyl safflower Brucine was in range from 0.0229 to 0.172μg, which presented a good linear relationship ( r=0.9991 ) .The average recovery was 96.65%, RSD was 0.94%.HPLC determined that hydroxyl safflower Strychnine was in range from 0.0423 to 0.317μg, which presented a good linear relationship ( r=0.9998) .The average recovery was 97.81%, RSD was 2.88%.Conclusion The meth
