| Abstract: | 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. |
