Abstract/Summary
Phytoremediation is a green technology that leverages the natural processes of plants to address pollution, making it a cost-effective and environmentally friendly alternative to conventional remediation methods. Pteris melanocaulon Fée, a species of the same genus as P. vittata L. (a well-known model for phytoremediation), was recently discovered to be a hyperaccumulator of Cu and As. This study investigates the elemental composition, phytochemical constituents, antioxidant activity, and potential therapeutic properties of P. melanocaulon fronds. XRF analysis identified significant concentrations of As (15.67 ± 1.15 mg kg⁻¹) and Al (1295.67 ± 266.77 mg kg⁻¹ as Al2O3), suggesting P. melanocaulon as a potential Al hyperaccumulator besides Cu and As. The plant's uptake of aluminum and its quantity in the soil were verified by SEM−EDS studies. Phytochemical tests on acetone extracts revealed the presence of terpenoids, phytosterols, and alkaloids. DPPH assays demonstrated concentration-dependent antioxidant activity, peaking at 30 μg mL⁻¹. GC−MS identified 25 volatile constituents, many of which have strong antioxidant properties. FTIR analysis revealed diverse organic compounds across different solvent extracts, emphasizing acetone's efficiency as an extraction solvent. In silico analysis of 25 compounds indicated varying bioavailability profiles, with several compounds demonstrating potential therapeutic interactions through multi-target protein engagement but exhibiting challenges in their water solubility. This is the first report that highlights the phytochemical diversity and potential health benefits of P. melanocaulon, warranting further research into its hyperaccumulation capabilities and bioactive compounds for therapeutic applications.
