We demonstrate a facile approach for smart time-saving extraction of active components of rutin and rhoifolinby a new kind of magnetic particles （MPs）. The inorganic borate functionalized magnetic particles are qua-si-spherical with an average diameter of 200--220 nm. The MPs were characterized by scanning electron micros-copy and X-ray diffraction techniques. The inorganic boron content in MPs was confirmed by electron-dispersiveX-ray spectroscopy. The extraction and release efficiency of MPs were investigated. The smart borate-decoratedmagnetic particles show a specific extraction towards the active components containing cis-1,2 diol moieties. Rutinand rhoifolin were extracted at 16.55 and 22.49 mg/g, respectively. The recycling test shows that MPs can be reusedand maintain a significant efficiency for seven cycles. Hence, a novel structured and reusable magnetic nanomateri-al for extracting rutin and rhoifolin was developed. This strategy of specific extraction will be an important methodto obtain the active components with some structure features through designing various structured particles.
