Abstract

Etlingera elatior a tropical plant commonly found in Indonesia, is traditionally used for its medicinal properties. However, limited studies have explored its bioactive content and antibacterial effects. This study aimed to identify the phytochemical constituents and evaluate the antibacterial activity of E. elatior fruit extract against Staphylococcus aureus. The fruit of E. elatior was collected from Pancur batu, Deli Serdang Regency, and subjected to hydroethanolic maceration. Phytochemical screening was conducted using standard qualitative methods to detect the presence of alkaloids, flavonoids, tannins, terpenoids, saponins, and phenolics. Antibacterial activity was assessed using the Kirby-Bauer disc diffusion method against S. aureus. Extract concentrations ranging from 0.078125% to 50% were tested, with chloramphenicol as the positive control and DMSO as the negative control. Zones of inhibition were measured and analyzed in triplicate. Phytochemical analysis revealed the presence of alkaloids, flavonoids, tannins, terpenoids, and phenolics, while saponins were absent. The extract demonstrated a concentration-dependent antibacterial effect, with the highest inhibition zone observed at 50% concentration (12.8 ± 1.52mm). No activity was recorded below 0.3125%. The positive control showed a significant inhibition zone (23.56 ± 2.43 mm), whereas the negative control showed none. The hydroethanolic extract of E. elatior fruit contains multiple bioactive compounds and exhibits notable antibacterial activity against S. aureus. These findings support its potential as a natural antibacterial agent and warrant further investigation into its therapeutic applications
