摘      要：Monogalactosyldiacylglycerols(MGDGs)have potential applications in food products,cosmetics and *** from microalgae with high amounts of polyunsaturated fatty acids(PUFAs)have potential functions,which arise the interest of the *** were prepared by silica gel column chromatography with the appropriate mobile phase,while due to the similarity to molecular structure of MGDGs,digalactosyldiacylglycerols(DGDGs)were the most difficult impurities to separate during the extraction process of MGDGs from Nannochloropsis oceanica IMET1 and Arthrospira *** order to obtain MGDGs from microalgae using low toxic solvent system,a novel material Click thiol-ene cysteine(Click TE-Cys)was employed to achieve its selective separation by differentiation of the hydrophilic *** mixture of MGDGs and DGDGs standards were separated from each other by Click TE-Cys solid phase extraction(SPE),which was further confirmed by the result of *** molecular interaction of MGDGs and DGDGs with Click TE-Cys demonstrated that DGDGs had more hydrogen bonds with Click TE-Cys material,which might cause a higher hydrophilic *** this study,the Click TE-Cys material exhibited higher hydrophilicity with DGDGs and effectively separated MGDGs from 4 species microalgae by‘flow-through mode using ethanol as mobile phase.
