Solid-phase extraction of ursolic acid from herb using β-cyclodextrin-based molecularly imprinted microspheres

A new method was employed to solid-phase extract ursolic acid from Ilex kudingcha C. J. Tseng using molecularly imprinted microspheres (MIMs) as the sorbent. Using a surface molecular imprinting technique, MIMs for ursolic acid were prepared with bonded β-CD and acrylamide in combination based on fu...
