高效液相色谱法同时测定补肾化瘀浸膏中淫羊藿苷及柚皮苷含量
Herald of Medicine(2014)
Abstract
目的:建立高效液相色谱法同时测定补肾化瘀浸膏中淫羊藿苷及柚皮苷含量。方法 C18柱(4.6 mm×250 mm,5μm),以乙腈-磷酸溶液(0.2%磷酸,pH=2.9)为流动相,梯度洗脱,流速0.8 mL·min-1,检测波长269 nm,柱温30℃。结果淫羊藿苷在0.3~3.0μg范围内线性关系良好(r=0.9999),加样回收率105.6%,RSD为0.95%;柚皮苷在0.12~1.20μg范围内线性关系良好(r=0.9999),加样回收率94.0%,RSD为0.52%。结论该方法操作简便,准确稳定,重复性好,可作为补肾化瘀浸膏的质量控制标准。
