Effect of magnetization on antibacterial, lipid-lowering and antioxidant activities of isoquinoline alkaloids.

ABSTRACT: The magnetization strategy of isoquinoline alkaloids has been successfully used in the extraction and isolation, but the effect of the magnetization on biological activities of those alkaloids still deserves further investigation. Therefore, the antibacterial, lipid-lowering and antioxidant activities of five isoquinoline alkaloids (berberine, tetrahydroberberine, palmatine, tetrahydropalmatine and tetrahydropapavine) before and after magnetization were compared in this study, and the results showed that the relevant activities were enhanced after magnetization. Additionally, among the five magnetic derivatives studied, berberine magnetic derivative ([Ber·H]⁺[FeCl₄]^-) had the best antibacterial effect on S. aureus and E. coli with MIC of 200 and 800 µM, res
