目的 :为山茱萸及其制剂中马钱素建立专属性含量测定方法。方法 :采用RP HPLC测定。固定相为YWG C18[4 .6 (i.d)× 2 5 0mm]色谱柱 ,流动相∶甲醇 水 (30∶70 ) ,检测波长为 2 36nm。结果 :马钱素的平均加样回收率为 97.6 5 % ,RSD为 1.2 2 % (n =5 )。结论 :本法简便、快速、重现性好 ,为山茱萸及其制剂的质量控制和评价提供了可靠的依据
Objective : To establish a method for determining the specific content of loganin in hawthorn and its preparations. Method : Determination by RP HPLC. The stationary phase was a YWG C18 [4 .6 (i.d) × 250 mm] column with a mobile phase of methanol water (30:70) and a detection wavelength of 236 nm. Results: The average recovery rate of loganin was 97.65%, and the RSD was 1.2 2% (n =5). Conclusion : This method is simple, rapid and reproducible, providing a reliable basis for the quality control and evaluation of hawthorn and its preparations.
