Abstract

This research evaluated the antibacterial potential of the aqueous, ethyl acetate, methanol, and decocted extracts of the shell and kernel of Atuna racemosa Rafin. Chrysobalanaceae (tabon-tabon). 

The antimicrobial screening was done against Escherichia coli and Staphylococcus aureus by paper disc diffusion method. The A. racemosa shell and kernel showed resistant to intermediate antimicrobial activity against E. coli and S. aureus in aqueous extracts with mean zone of inhibition of 7.7 mm and 9.8 mm, ethyl acetate extracts with 9.2 mm and 12.8 mm, methanol extracts with 9.5 mm and 13.2 mm, and decoction extracts with 7.3 mm and 11.0 mm, respectively. Ethyl acetate extracts with the highest antibacterial activity against E. coli obtained minimum inhibitory concentration values of 0.11375 mg/mL in shell and 2.92 mg/mL in kernel for both bacterial strains. Methanol extracts with the highest antibacterial activity against S. aureus obtained minimum inhibitory concentration values of 0.81375 mg/mL in shell for both test organisms, and 8.57 mg/mL for E. coli and 2.138 mg/mL for S. aureus in kernel. Overall, the ethyl acetate and methanol extracts of A. racemosa kernel showed good antibacterial potential against bacterial strains. Further investigation is needed to determine the bioactive components present in these extracts.
