【摘要】 目的建立脑灵颗粒剂中淫羊藿苷的含量测定方法。方法采用水溶解醋酸乙酯提取-聚酰胺小柱纯化去杂方法制备供试品。HPLC法,C18柱,甲醇-0.1mol/L磷酸二氢钠水溶液(6∶5)为流动相,检测波长270nm。按外标法检测。结果淫羊藿苷在0.24～1.20μg之间呈线性关系,r=0.9998,样品平均回收率为98.2%,RSD为1.3%(N=5)。结论该方法简便,重现性好,可作为脑灵颗粒剂的含量测定方法。更多还原

【Abstract】 Objective: To establish a method for determinating icarin content in Naoling Granule. Methods: Water-soluble ethyl-acetate-extracting polyamide column purification was adopted. The content of icarin was determined by HPLC. C18 column was used, mobile phase was methanol:0.1mol/mL sodium phosphate dibasic (6:5) and detection wavelength was at 270nm. Results: Icarin has a good linearity in the range of 0.24～1.2μg ( r=0.9998). The average recovery was 98.23 %and RSD was 1.2 %(N=5). Conclusion: The method was simple with good reproducibility and can be used for the content determination of icarin in Naoling Granule.更多还原
