Abstract

Lichens, formed by the symbiosis of fungi and algae or cyanobacteria, are increasingly recognized for their potential medicinal properties, including their potential to treat type 2 diabetes. Many studies have shown that the bioactive metabolites of lichens originate from their fungal partners. This study isolated the mycobiont from a Graphis lichen sample and investigated the antioxidant and α-glucosidase inhibitory activity of its ethyl acetate extract. The extract exhibited weak DPPH radical scavenging activity but a significant α-glucosidase inhibitory activity, with an IC50 value of 43.3 ± 1.9 μg/mL. The results suggest that lichens have the potential to control postprandial hyperglycemia and highlight the potential of Graphis sp. mycobionts as a promising source for the management of type 2 diabetes.
