“…PSM can improve the selective and chemical stability of Fe 3 O 4 MNPs, which have been used to adsorb various metabolites, medicines, and pollutants. For enrichment by MSPE and detection of PAs from plant oil samples, a thermo‐responsive adsorbent was prepared by Li et al [60]. Fe 3 O 4 @PGMA@PNIPAAm NPs were prepared through PSM using Fe 3 O 4 as magnetic core, PNIPAAm as a thermo‐responsive agent, and PGMA as graft linker.…”

Sample preparation, including extraction, separation, and purification, is a vital process for natural product analysis. As an attractive sample pretreatment method, magnetic solid‐phase extraction (MSPE) has gained plenty of attention, mainly due to its simpler operation, less consumption of organic solvents, and shorter processing time than traditional SPE. This updated review is devoted to summarizing the applications of MSPE based on different magnetic nanomaterials in the analysis of various natural products in complex matrixes, such as biological samples, plants, and Chinese herbal preparations in the past four years (2020–2023). The preparation and fabrication of different materials are briefly introduced. Furthermore, the extraction mechanism and interaction forces between adsorbent and analytes are elaborated, and the advantages and disadvantages of different adsorbents coupled with various analytical methods for MSPE of different natural products are summarized. Moreover, the future trends and opportunities for MSPE in the natural product analysis are discussed. It is expected that this work can provide updated information for future research on the applications of MSPE in such fields.
