In vitro antibacterial and antifungal activities of Belimbing Buluh (Averrhoa bilimbi) leaves extracts against common human pathogen / Nur Izzati Hairuddin
Averrhoa bilimbi or commonly known as Bilimbing Buluh from family Oxalidiceae has been used in this study. Medicinal plants contain substances that can be used as therapeutic purposes and chemo-pharmaceutical. Traditionally, the fruits are used for blood pressure systems and cure beriberi and cough,...

The aims of this study were to determine the antibacterial and antifungal activities of A. bilimbi leaves extract against human pathogens.

Antibacterial activity results showed larger zone of inhibition for methanol A. bilimbi leaf extract against S. aureus and E. coli at concentration 600 µg/µL and 800 µg/µL with diameter of 6.00 mm and 9.20 mm, whereas for distilled water, the larger zone of inhibition against S. aureus at concentration 800 µg/µL with 1.80 mm diameter and E. coli at concentration 200 µg/µL with diameter of 2.40 mm. The antifungal study showed that methanol extract gave the larger inhibition zone only against C. albicans which the diameter was 1.90 mm at concentration 200 µg/µL, whereas distilled water leaves extract against C. albicans showed higher inhibitory activity at concentration 800 µg/µL with 2.80 mm diameter.

MIC of A. bilimbi leaves extract against C. albicans for methanol extract at 600 µg/µL and at 800 µg/µL for distilled water extract.
