Abstract

The cause of infectious diseases that often occur in humans can be caused by pathogenic bacteria such as Staphylococcus aureus. The high rate of resistance caused by Staphylococcus aureus makes scientists continue to try to find secondary metabolites for safe medicinal ingredients. This study aims to identify fatty acids and determine the potential of avocado seed oil (BA) against Staphylococcus aureus. This type of research is a laboratory experimental research. The identification of fatty acids that make up BA oil is carried out by gas chromatography (GC) analysis, resulting in several free fatty acids (ALB) in the identified BA oil, such as saturated fatty acids and unsaturated fatty acids. The highest percent of three ALB components of BA oil were found in linoleic acid (26.182%), oleic acid (17.05%), and palmitic acid (12.21%). While the antibacterial activity test was carried out using the disc diffusion method, the variations in the concentration of BA oil used were 25%, 50%, 75%, and 100% with dimethyl sufoxide as K(-) and ciprofloxacin as K(+). Based on the antibacterial activity test, it is known that BA oil can inhibit the growth of Staphylococcus aureus bacteria with a weak category of <10 mm.

Abstract

Kerai Payung (Filicium decipiens) belongs to the Sapindaceae family, which contains several active compounds that can be used as antibacterial. This study aims to determine secondary metabolites contained in the parasol leaf and the antibacterial activity of n-hexane fraction of the parasol leaf against Staphylococcus epidermidis bacteria. Identification of compound components in the n-hexane fraction of Kerai Payung leaves was carried out qualitatively by TLC using a solvent ratio of n-hexane: ethyl acetate (9:1), (8:2) and (7:3). The best separation result was using nhexane:ethyl acetate (7:3) solvent to produce 7 spots visible at 366 nm UV. The antibacterial activity was tested using the disc diffusion method (Kirby and Bauer diffusion). The concentration variations of the n-hexane fraction were 25%, 50%, 75%, 100%, control (+) cifroploxacin and control (-) DMSO (Dimethyl sulfoxide). The results of the antibacterial test against Staphylococcus epidermidis showed that the average value of the largest inhibition zone diameter was obtained at a concentration of 75%, which was 12.77 mm. The concentration groups of 25%, 50%, and 100% were 9.77 mm, 11.42 mm, 10.75 mm, respectively. Meanwhile, the K(+) group, namely Cifrofloxacin, was 31.95 mm.
