建立了高效液相色谱同时测定中药材虎掌南星中核苷类活性成分(腺嘌呤、次黄嘌呤、黄嘌呤、尿苷、胸腺嘧啶、腺苷、鸟苷)含量的方法.以Lichrospher C18色谱柱(150 mm×4.6 mm, 5 μm)分离,以乙腈-水(含0.1%甲酸)为流动相,梯度洗脱,在254 nm下检测,腺嘌呤、次黄嘌呤、黄嘌呤、尿苷及鸟苷分别在1.6～50 mg/L 范围内、胸腺嘧啶和腺苷分别在1.2～40 mg/L 范围内的线性关系良好,相关系数均大于 0.9995,加标回收率为98.9% ～101.2% ,相对标准偏差均小于3% .方法学考察结果显示符合含量测定要求,并应用于不同产地虎掌南星的测定.该方法操作简便、快速,结果可靠,重现性好,可作为虎掌南星质量评价的参考依据.
