高效液相色谱法测定五加参颗粒中紫丁香苷含量
China Pharmaceuticals(2012)
Abstract
目的建立测定五加参颗粒中紫丁香苷含量的高效液相色谱法。方法采用Agilent C18色谱柱(250 mm×4.6 mm,5μm),流动相为乙腈-0.3%甲酸溶液(体积比12∶88),流速为1.0 mL/min,检测波长为265 nm,柱温为30℃。结果紫丁香苷进样量在0.041 04~0.451 4μg(r=0.999 9)范围内与峰面积积分值线性关系良好,平均加样回收率为101.50%,RSD=1.96%(n=6)。结论高效液相色谱法灵敏度高、操作简便、准确可靠,可用于五加参颗粒中紫丁香苷的含量测定。
