摘要： Nanoparticles synthesized from natural sources are gaining prominence for their unique physicochemical properties and biocompatibility. This study investigates the potential of wild mushrooms, specifically Chlorophyllum molybdites (Lepiota morganii, green-spored parasol), for the green synthesis of manganese oxide nanoparticles. Mycosynthesized nanoparticles (NPs) were characterized via spectroscopic techniques such as XRD, UV spectroscopy, FTIR, and microscopic techniques such as SEM, and EDX, confirming their crystalline structure, spherical morphology, and a nanoscale size of 19.85 nm. FTIR analysis identified functional groups such as flavonoids, phenolics, and proteins, suggesting their role in nanoparticle stabilization and biological activity. Biocompatibility assays demonstrated minimal hemolysis (0.109 +/- 0.05% at 400 mu g/mL), indicating safety for biomedical use. Antileishmanial activity against Leishmania tropica (a flagellate parasite) revealed concentration-dependent inhibition, with IC50 values of 250 mu g/ml and 224 mu g/ml for promastigotes and amastigotes, correspondingly. Cytotoxic effects on HepG2 liver cancer cells were evaluated using MTT and crystal violet assays, showing significant dose-dependent reduction in cell viability (IC50 = 50 mu g/mL) and apoptosis induction. Furthermore, comparative MTT assays confirmed enhanced efficacy of nanoparticles synthesized with Chlorophyllum molybdites. These results confirmed the multifaceted biomedical effeciacy of mycosynthesized nanoparticles, including anticancer and antiparasitic applications, while promoting sustainable nanoparticle synthesis.
