Abstract

The use of extracts from medicinal plants in the community is used to prevent diseases, maintain body freshness and treat diseases. Guava leaves (Psidium guajava L) contain active compounds such as tannins, triterpenoids, flavonoids, saponins, alkaloids, and essential oils that have antibacterial effects. This study aims to determine the antibacterial activity of liquid soap ethanol extract of guava leaves against Staphylococcus aureus bacteria. The liquid soap formula of guava leaf extract (Psidium guajava L) is made into 4 formulas F0 (0%), F1(5%), F2(10%), and F3(15%). Antibacterial activity is seen from the antibacterial activity test using the diffusion method. Physical testing of guava leaf ethanol extract liquid soap includes organoleptic, pH, foam height, homogeneity, and viscosity. The results of the study showed that the entire formula qualified for good physical properties and could inhibit the growth of Staphylococcus aureus. The results of the antibacterial activity test showed that guava leaf extract soap (Psidium guajava L) had an inhibition in the formula F0 of 0.00±0.00 mm (no antibacterial activity), F1 of 4.60±0.46 mm (weak antibacterial activity), F2 of 5.27±0.06 mm (moderate antibacterial activity), F3 of 5.93±0.32 mm of moderate antibacterial activity) and a positive control of 11.77±1.46 mm (strong antibacterial activity). Based on the results of the study, it was concluded that the liquid soap formula of guava leaf extract (Psidium guajava L) has good physical properties and shows antibacterial activity against Staphylococcus aureus, and does not differ significantly (p<0.05).

Abstract

Inflammation of the hair follicles and sebaceous glands causes acne, a common skin disorder often triggered by bacterial infections such as Propionibacterium acnes. This study aims to determine the antibacterial activity of an ethanolic extract of purple passion fruit seeds against Propionibacterium acnes. The extraction process was carried out by maceration using 96% ethanol. The antibacterial activity of the extract was tested using the disk diffusion method (Kirby-Bauer) at concentrations of 10%, 20%, and 30%, with positive control (clindamycin) and negative control (1% DMSO) for comparison. Antibacterial activity was measured based on the inhibition zone diameter. The data obtained were then statistically analyzed using a one-way ANOVA test with a 95% confidence level. The extract yield was 5.78% and contained chemical compounds such as flavonoids, alkaloids, tannins, saponins, and terpenoids. The antibacterial test results showed inhibition zones for the 10%, 20%, and 30% extract concentrations and the positive control (clindamycin) of (6.45 ± 1.86) mm (moderate activity), (10.38 ± 0.29) mm (strong activity), (12.21 ± 1.21) mm (strong activity), and (17.78 ± 0.55) mm, respectively. Statistically, there was a significant difference in antibacterial activity between the samples (p-value < 0.05). In conclusion, the ethanolic extract of passion fruit seeds possesses antibacterial properties effective against Propionibacterium acnes..   Keywords: antibacterial, seed, Passiflora edulis Sims, Kirby_bauer, acne
