摘要
用反相高效液相色谱法测定家兔血浆中赤芍801PG浓度。采用NucieoselC18色谱柱,甲醇∶水∶冰乙酸(48∶50∶2)为流动相,4羟基苯甲酸乙酯为内标物,紫外检测波长275nm,对ivPG后不同时间家兔血浆中药物含量进行测定。结果表明:PG浓度为2.5μg/ml的平均回收率为96.70%,其RSD=1.83%。浓度5μg/ml的样品平均回收率为98.86%,RSD=1.05%。其最低检测限为0.1μg/ml。
A HPLC method was used to determine the content of Radix Paeoniae Rubar (Chishao) 801 in rabbit's plasma, using Nucleosil C 18 column, methanol, water and glacial acetic acid (48∶50∶2) as mobile phase ethye 4 hydroxybenzoate as internal standard,and UV detector(λ max ∶275nm, AUFS∶0.02).The average recovery was 96.70% (C:2.5μg/ml) and 98.86%(C: 5μg/ml) respectively. The lowest determination limit was 0.1 μg/ml.The method is simple, accurate, sensitive and reliable.
