• Abstract

    Diabetic ulcers are serious complications of diabetes mellitus (DM) affecting several individuals around the world. These complications are caused by impaired blood circulation to peripheral tissue and are further exacerbated by infection due to chronic hyperglycemia, leading to tissue death. Several types of bacteria have been reported to cause infection in diabetic ulcers patients, including Staphylococcus aureus, Staphylococcus epidermis, Proteus mirabilis, Proteus vulgaris, Pseudomonas aeruginosa, Klebsiella pneumoniae, and E. coli. This indicates that there is a pressing need to develop herbal products to minimize complications. Therefore, this study aims to determine antibacterial activity of Patiwala leaves (Lantana camara) ethanol extract against bacteria that cause diabetic ulcers. The identification of bioactive compounds from the ethanol extract of patiwala leaves was carried out qualitatively and antibacterial activity using the Kirby Bauer diffusion method in triplicate. The results showed that Patiwala leaves ethanol extract with a concentration of 100 mg/mL had a strong inhibitory power against Staphylococcus aureus, Staphylococcus epidermis, and Pseudomonas aeruginosa, with values of 18 ± 0.00, 19 ± 0.00 and 18 ± 0.00 (p< 0.05), respectively. Klebsiella pneumonia and E. coli bacteria showed strong potential as inhibitors at a concentration of 200 mg/mL, with an average zone of inhibition of 19 ± 0.00 and 20 ± 0.00 (p < 0.05). Meanwhile, Proteus mirabilis and Proteus vulgaris had moderate inhibitory potential ranging from concentrations of 25-200 mg/mL, with an average of 15 ± 0.00 to 16 ± 2.00 (p < 0.05). Based on these results, Patiwala leaves ethanol extract has the potential to be developed as antibacterial in diabetic ulcers.
