目的 分離純化阿可拉定（淫羊藿苷，IC-162）的主要有關(guān)物質(zhì)，進(jìn)行結(jié)構(gòu)確證。方法 利用反相硅膠和凝膠柱色譜分離阿可拉定中的2個主要雜質(zhì)，經(jīng)化合物譜圖數(shù)據(jù)（LC-DAD、LC-MS、¹H-NMR和¹³C-NMR）鑒定其結(jié)構(gòu)。結(jié)果 阿可拉定中2個主要雜質(zhì)分別為8-異戊烯基山柰酚和朝藿素B。結(jié)論 阿可拉定有關(guān)物質(zhì)的定量和定性研究可以為制定合理的雜質(zhì)限度提供依據(jù)。

Objective To purify and identify the main related substances of icraiin (IC-162). Methods Two main impurities were isolated from IC-162 with reverse phase silica gel and Sephedax LH-20. The structural characteristics of impurities were determined by spectral methods, such as LC-DAD, LC-MS, ¹H-NMR, and ¹³C-NMR. Results The structures of two impurities were identified as 8-isopentenyl kaempferol and epimedokoreanin B. Conclusion With the quantitative and qualitative studies, the related impurities will be controlled in the reasonable limit.
