Abstract

Objective:The aim of this study was to examine the influence of the partial hydrolysis of virgin coconut oil (VCO) on it’s antibacterial activity.

Methods:The VCO used in this study was the productof UD SinarNias. Hydrolysis was carried out by enzyme and sodium hydroxide. Enzymatic hydrolysis using lipozyme was conducted in four different incubation time namely, 3 hours, 6 hours, 9 hours and 12 hours. Alkaline hydrolysis preformed with 25%, 50% and 75% NaOH calculated from the saponification number for coconut oil. Acidified hydrolyzed VCO was extracted with n-hexane. Recovered hydrolyzed products were mixed with water (5 g in water to make 10 ml) to form water in oil emulsion (w/o). Antibacterial activity test was conducted against bacteria Pseudomonasaeruginosa (ATCC 25619), Staphylococcusaureus (ATCC 29737), Staphylococcus epidermidis (ATCC 12228) and Propionibacterium acnes (ATCC 6918) by diffusion agar method using the paper disc of 6 mm in diameter. Antibacterial activity of hydrolyzed VCO was compared with tetracycline and ampicillin.

Results: Un-hydrolyzed VCO did not show antibacterial activity but hydrolyzed oil did.  The longer the incubation time and the higher the amount of NaOH used in the hydrolysis increased antibacterial activity. VCO hydrolyzed by enzyme was more effective than those hydrolyzed by sodium hydroxide. Hydrolyzed VCO were more effective against Pseudomonas aeruginosa than other bacteria.

Conclusions: Un-hydrolyzed VCO did not inhibit bacterial growth, while VCO after hydrolysis was found to have antibacterial activity. Hydrolyzed VCO by enzyme is more active as antibacterial than VCOhydrolyzed by NaOH. Tetracyclin and ampicillin were more active than those of hydrolyzed VCO.
