中文摘要
目的建立HPLC法测定射干提取物中射干苷和鸢尾黄素的含量。方法采用Kromasil C18色谱柱(250 mm×4.6mm,5μm),以水(磷酸调pH3)-甲醇(45∶55)为流动相,流速0.8 mL.min-1,柱温35℃,检测波长265 nm。结果射干苷、鸢尾黄素得到有效分离,回归方程分别为:Y射干苷=1.953×105X+5.847×103(r=0.9999);Y鸢尾黄素=2.504×105X+1.887×104(r=0.9999);线性范围为0.2~10.0μg.mL-1;平均回收率分别为101.01%±1.02%、99.49%±1.34%;RSD分别为1.01%、1.35%(n=6)。结论所建方法操作简便、准确,重复性好,可用于同时测定射干提取物中的射干苷和鸢尾黄素。
