  • Applications

    Icariside B8 (CAS 126176-78-1) is a natural flavonol glycoside derived from Epimedium species. In practice, its primary applications lie in pharmaceutical/natural product research and analytical quality control, where it is used as a reference standard for evaluating Epimedium extracts (for example in HPLC/LC-MS methods). It is also explored as an intermediate or building block for the synthesis of related flavonoids in research and development. Additionally, it may be evaluated for cosmetic formulations as a natural antioxidant or stabilizer, and it may appear in botanical dietary supplements based on Epimedium constituents, subject to local regulations.
