Abstract
Lignosus cameronensis holds promise for exploration given its morphological likeness to the renowned Lignosus rhinocerus, or tiger milk mushroom. Investigating its potential medicinal and industrial applications addresses a significant knowledge gap in this field. A comparative analysis with other Lignosus species and cultivars provides insights into biopharmacological potential. L. cameronensis cold water extract (LC-CWE) displayed moderate antioxidant activity, demonstrating promising Trolox equivalent antioxidant capacity. Variable cytotoxicity was observed in different cell lines, with an IC50 of 215 μg/ml against breast cancer cells (MCF-7) cells. LC-CWE exhibited anti-inflammatory potential with an ED50 of 60 mg/kg in a λ-carrageenan-induced rat paw oedema model. Comparison with other Lignosus species and cultivars emphasised LC-CWE’s distinct attributes, including high phenolic content and moderate antioxidant capacity. LC-CWE displayed potential in selectively inhibiting MCF-7 cells and reducing inflammation, highlighting its medicinal promise. This research expands our understanding of L. cameronensis and underscores the need for further mechanistic exploration.
