A comparative antioxidant, antimicrobial, and biocompatible potential of various extracts of Solanum virginianum
Abstract
Oral health challenges, such as microbial resistance, biofilm formation, and oxidative stress, necessitate innovative therapeutic solutions in dental care. This study evaluates the extraction yield, antioxidant, antimicrobial, and biocompatibility potential of Solanum virginianum extracts using aqueous and ethanolic solvents. The extraction yield was noticed to be higher in the ethanolic solvent than in the water extraction. The antioxidant potential was assessed using the DPPH assay, where ethanolic extracts demonstrated superior radical scavenging activity than the aqueous extracts. Antimicrobial efficacy was evaluated against important oral pathogens, Streptococcus mutans, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, using agar well diffusion methods. The outcome of the antibacterial assay showed that ethanolic extracts revealed enhanced antibacterial activity against these pathogens compared with the water extract. The highest antibacterial activity was observed against Pseudomonas aeruginosa (18 mm), followed by S. mutans, S. aureus, and E. coli. Further, biocompatibility of the extracts was studied by analyzing the toxicity in zebrafish embryos and in vitro hemolytic assays, which also implies that they did not impose any toxicity, suggesting their safe usage in therapeutic applications. This study highlights S. virginianum, particularly ethanolic extracts, as a promising natural resource for oral care and clinical applications. Their robust antioxidant and antimicrobial properties, combined with excellent biocompatibility, may position them as viable alternatives to conventional and synthetic drugs. Future research should focus on clinical trials and formulation development to fully harness their therapeutic potential in therapeutic interventions.
