Integrative taxonomy and metabolite profiling reveal functional divergence among wild edible Termitomyces from Indonesia.

The methanolic extract of Termitomyces eurrhizus from Indonesia showed the strongest antioxidant activity, while the water extract of Termitomyces intermedius had the highest ABTS radical scavenging activity.

• Why it matters: Comparative metabolite diversity and how it relates to functional variation among wild edible Termitomyces species is poorly understood, limiting targeted discovery of bioactive natural products.
• What they did: Three Indonesian wild edible Termitomyces species were integratively characterized using morphology, ITS rDNA phylogeny, proximate analysis, and metabolite profiling, then tested for antioxidant, antibacterial, and α-glucosidase inhibitory activities using water, methanol, ethyl acetate, and n-hexane extracts.
• The result: Species-specific metabolite profiles were distinct, including ergothioneine, anthranilic acid, hypoxanthine, p-coumaric acid, anthraquinones, and γ-linolenic acid, which may contribute to functional differences among Termitomyces species.
