摘要
目的:建立高效液相色谱法测定山奈酚胃漂浮缓释片中主药含量的方法。方法:色谱柱为Hypersil ODS C18,流动相为甲醇-0.4%醋酸溶液(48∶52),流速为0.8mL·min-1,检测波长为360nm,柱温为45℃。结果:山奈酚检测浓度线性范围为5.0~40.0μg·mL-1(r=0.9997);方法回收率为100.29%,RSD=1.77%(n=6)。结论:本方法灵敏、准确、专属性强,可用于山奈酚胃漂浮缓释片中主药含量的测定。
OBJECTIVE:To establish the HPLC method for the content determination of kaempferol in Kaempferol gastric floating sustained-release tablets.METHODS:Hypersil ODS column was adopted with mobile phase consisted of methanol-0.4% acetic acid solution(48:52) at flow rate of 0.8 mL·min^-1.The detection wavelength was set at 360 nm and column temperature was 45 ℃.RESULTS:The linear range of kaempferol was 5.0~40.0 μg·mL-1(r=0.999 7) with an average recovery of 100.29%(RSD=1.77%,n=6).CONCLUSION:The method is sensitive,accurate and specific.It is suitable for the content determination of kaempferol in Kaempferol gastric floating sustained-release tablets.
