Abstract: The aim of this research was to extract total phenolics from clove seeds, ginger rhizomes, and Tecoma flowers using various polar solvents, followed by quantification using the Folin method. Subsequently, the antioxidant activity was evaluated using DPPH assay, and the antibacterial activity against two strains of Gram-positive bacteria, Staphylococcus aureus, and Gram-negative bacteria, Escherichia coli, was assessed using the disc diffusion method. The results demonstrated the superiority of clove seed extract over other extracts in terms of total phenolic content (816.47 mg GAE/10g), antioxidant activity (73.8%), and the inhibitory concentration of 50% DPPH (0.015 mg/mL). Plant extracts exhibited efficacy against Gram-positive bacteria, while no activity was observed against Gram-negative bacteria. These findings suggest the potential use of total antioxidants extracted from clove seeds and ginger rhizomes in the medical or industrial fields as alternatives to synthetic antioxidants.
