ABSTRACT / SAŽETAK:

This study investigates the antimicrobial and antioxidant potential of methanolic extract of mushroom Xerocomus subtomentosus. The antimicrobial potential was assessed by microdilution method (MIC values ranged from 5 to 40 mg/mL). Antioxidant activity was evaluated using DPPH, ABTS and reducing power assays, alongside total phenol and flavonoid content measurements. The extract demonstrated strong antioxidant potential (IC50: 80.842 μg/mL for DPPH, 6.587 μg/mL for ABTS, while absorbance for reducing power ranged from 0.380 to 1.168). Total phenolics and flavonoids were 40.439 μg PE/mg and 3.899 μg RE/mg. This study confirms that X. subtomentosus is a valuable source of natural antioxidants.
