Implication

In vitro characterization study identifies novel citrinin dimers from Penicillium citrinum with potent antioxidant activity, highlighting halotolerant fungi as sources of bioactive metabolites.

Key Points

To isolate and characterize structurally novel and bioactive secondary metabolites from the halotolerant fungal strain Penicillium citrinum B-57.
Isolated the halotolerant fungus Penicillium citrinum B-57 from sediment samples collected at the Jilantai salt field.
Extracted secondary metabolites using ethyl acetate and elucidated chemical structures via spectroscopic and chemical methods.
Assayed antioxidant radical-scavenging activity against DPPH radicals to determine IC50 values.
Isolated two novel citrinin dimers, designated pennicitrinone C (1) and penicitrinol B (2), alongside 11 known related compounds.
Demonstrated antioxidant activity against DPPH radicals across the isolated compounds, with IC50 values ranging from 0.8 to 59 µM.
