Abstract: 目的 制定高效液相色谱法测定芪归祛白胶囊中梣酮含量的方法.方法 色谱柱:Zorbax C18柱(十八烷基硅烷键合硅胶为填充剂,4.6mm×250 mm,5μm);柱温:室温(25℃);流动相:甲醇-水(56∶44);流速:1.0ml·min-1;进样量:20μl.检测波长:218nm.结果 当梣酮浓度在1.5~9.0μg·ml-1范围内时呈良好的线性关系,回归方程:Y=3.4857×104X-1.3422×103,r=0.9997.平均回收率98.71%,RSD为1.09%,n=5.梣酮与其它杂质峰达基线分离,梣酮周围无杂质,分离度达2以上.结论 采用高效液相色谱法测定芪归祛白胶囊中梣酮的含量,操作较简便、灵敏度高、阴性无干扰,能较好地控制芪归祛白胶囊中梣酮的含量.
