AbstractWe demonstrate a facile approach for smart time‐saving extraction of active components of rutin and rhoifolin by a new kind of magnetic particles (MPs). The inorganic borate functionalized magnetic particles are quasi‐spherical with an average diameter of 200–220 nm. The MPs were characterized by scanning electron microscopy and X‐ray diffraction techniques. The inorganic boron content in MPs was confirmed by electron‐dispersive X‐ray spectroscopy. The extraction and release efficiency of MPs were investigated. The smart borate‐decorated magnetic particles show a specific extraction towards the active components containing cis‐1,2 diol moieties. Rutin and rhoifolin were extracted at 16.55 and 22.49 mg/g, respectively. The recycling test shows that MPs can be reused and maintain a significant efficiency for seven cycles. Hence, a novel structured and reusable magnetic nanomaterial for extracting rutin and rhoifolin was developed. This strategy of specific extraction will be an important method to obtain the active components with some structure features through designing various structured particles.
