摘要
目的:建立一种高效液相色谱法测定暖宫孕子胶囊中芍药苷含量的方法.方法:用C18ODS2色谱柱;以甲醇-0.05moL/L磷酸二氢钾溶液-醋酸-异丙醇(67:173:4:4)为流动相;流速为1.0 mL/min;检测波长为230 nm;柱温为25℃.结果芍药苷在0.087~0.435 ug范围内呈良好的线性关系,r=0.9997,平均回收率为96.4%(RSD=1.2%).结论该方法简便、快捷、准确.
Objective Establish a HPLC method for the determination of Paeoniflorin in Nuangong Yunzi Pill. Methods The determination was performed on C18 ODS(5 um,4.6 mm × 250 mm) column, the mobile phase consisted of Methanol - ( 0.05 moL/L) KH2 P3O4 - aceticacid-isopmpanol ( 67: 173 : 4: 4), the detection wavelength was set at 230nm , the flow rate at 1.0 mL/min, and column temperature was 25 ℃. Results Good linear relation was achievedwhen sample size ranged at 0.087 ~ 0.435 ug(r = 0.9997), and the average recovery at 96.4% (RSD = 1.2% ). Conclusions The method was simple, rapid and accurate.
