The films were produced through incorporating V. negundo extract, obtained from Soxhlet extraction, into an alginate-bacterial cellulose matrix at concentrations of 0.25% and 0.5%. The results indicated that increasing the extract concentration improved the bioactive characteristics of the films. The 0.5% film demonstrated enhanced antibacterial efficacy, with inhibition zone widths rising by 23.33% for Bacillus subtilis and 12% for Escherichia coli. In addition, antioxidant activity markedly boosted, proven by an increased DPPH scavenging rate of 72.92% in contrast to 54.94% for the 0.25% film. FTIR measurement validated the successful incorporation of the plant extract, evidenced by more prominent functional group peaks in the 0.5% film, signifying an elevated concentration of bioactive compounds. The resultsindicate that V. negundo-derived films had the potential to offer long-lasting and effective antibacterial and antioxidant treatments, underscoring the necessity of optimising extract concentration for improved efficacy.
