Abstract: 目的 对蒲地蓝消炎片进行定性定量方法研究.方法 对处方中的黄芩、蒲公英、苦地丁、板蓝根4味药材采用显微或薄层色谱(TLC)进行鉴别,采用高效液相色谱法测定黄芩中有效成分黄芩苷的含量,C18色谱柱,流动相:甲醇-水-磷酸(47:53:0.2)为流动相,检测波长280 nm,流速为1.0 mL·min-1.结果 在薄层色谱中可检出黄芩、蒲公英、苦地丁、板蓝根,含量测定中黄芩苷进样量在5.008~100.16μg范围内线性关系良好(r=0.9998);黄芩苷的加样回收率为98.87%,RSD为0.95%(n=9).结论 本方法操作简单,受外界干扰因素少,重现性好,可用于蒲地蓝消炎片的质量控制.
