【Abstract】 Metal-organic frameworks（MOFs）,owing to their readily modifiable structural features and distinctive molecular sieve effects,enable efficient enrichment of target compounds,thereby exhibiting vast potential applications in fields such as environmental science,food safety and medicinal health. In this study,MOF-808 was as carriers to achieve enrichment and extraction of alkaloid bioactive components from Coptis chinensis（Huanglian）. Furthermore,we delved into the synergistic interactions during the extraction process of these alkaloids using MOFs in conjunction with low-co-solvent systems,based on their structural characteristics. By optimizing conditions such as incubation and extraction procedures,it achieved a remarkable recovery of 85. 78% for jatrorrhizine from crude extracts of Huanglian. In addition,it boasted a wide linear range spanning from 0. 1 to 300 μg·L^-1,with ultra-low detection limits ranging from 0. 02-0. 05 μg·L^-1 and relative standard deviations maintained within 0. 40%-4. 7%. Additionally, for jatrorrhizine, epiberberine, coptisine, palmatine and berberine in the Huanglian crude extract matrix, the spiked recoveries reached an impressive range of 69. 7% to 128%. This approach efficiently and rapidly enriches and extracts alkaloid bioactive components from the Huanglian,thereby offering a novel perspective for the research on the selective extraction and enrichment of active ingredients in traditional Chinese medicines using MOFs materials.更多还原
