摘要： Indole-3-carbinol (I3C) is a type of natural anticancer while the low extraction efficiency of I3C limits its application. In this study, a novel two-dimensional metal-organic framework Cu-TCPP @AuNPs-MPB was syn-thesized by chemical precipitation and in situ polymerization, used for enrich I3C in cruciferous vegetables. The synthesized material was analyzed by Scanning electron microscopy (SEM), X-ray diffraction (XRD), Element analysis (EA), Inductively coupled plasma (ICP), Fourier transform infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET) and X-ray photoelectron spectroscopy (XPS). Cu-TCPP@AuNPs-MPB loaded with MPB realized specific adsorption of I3C, a large number of properties and easily dispersed in aqueous solution, which provided more enrichment sites for I3C and greatly improved the efficiency of enrichment. It was found that 93% 200 mu g/mL I3C could be enriched by per 20 mg Cu-TCPP@AuNPs-MPB within 30 min under optimal conditions. Combined with HPLC-MS/MS quantitative detection technology, a complete set of enrichment detection system has been constructed to enrich I3C in cruciferous vegetables. The whole process with high efficiency avoids the use of toxic solvents, which is environmental friendly, providing a new reference for production applications in the I3C industry.
