Abstract

Background: Cassia alata leaves, also known as petai cina or gelinggang in Indonesia, are commonly used to treat skin ailments. Objective: The purpose of this study is to test whether stem of C. alata has antibacterial activity against Staphylococcus aureus. Methods: C. alata stems were extracted using an ultrasound-assisted extraction method. For antibacterial activity, disc diffusion was used with extract concentrations of 25%, 50%, 75%, and 100%. Results: The inhibition zones of the ethanol extract of C. alata stems at 25%, 50%, and 75% concentrations were 17.6 mm, 21 mm, and 22.6 mm, respectively, with the highest inhibition zone at 100% concentration at 25 mm. Conclusion: The ethanolic extract of C. alata stems has a strong inhibitory effect on Staphylococcus aureus.

Abstract

Background: Acne, a prevalent skin condition, can arise from factors such as an unhealthy lifestyle, dietary habits, hormonal imbalances, and bacterial infections. Propionibacterium acnes is a notable bacterium responsible for acne. In South Borneo, the pericarpium of the limpasu plant (Baccaurea lanceolata) is traditionally used to treat acne. Objective: This study aims to scientifically validate the empirical antibacterial effects of limpasu pericarpium against Propionibacterium acnes, as reported by the communities in South Borneo. Methods: The ultrasound-assisted extraction (UAE) method was utilized to extract compounds from limpasu pericarpium. The antibacterial activity of the limpasu pericarpium extract was evaluated using the disc diffusion method at concentrations of 20%, 40%, 60%, 80%, and 100% w/v. Clindamycin served as the positive control, and 1% DMSO was the negative control. Results: The lowest concentration (20%) fell within the strong activity category, producing a clear zone diameter of 18.76 mm. Higher concentrations (40%, 60%, 80%, and 100%) demonstrated more potent antibacterial effects, with inhibition zones of 23.23 mm, 26.06 mm, 26.93 mm, and 27.33 mm, respectively. Notably, 60% to 100% concentrations exhibited greater inhibitory effects than the positive control, clindamycin, which had an inhibition zone of 25.23 mm. Conclusion: The study confirms the antibacterial properties of limpasu pericarpium against Propionibacterium acnes, supporting the traditional claims of its efficacy by the South Borneo communities.
