Abstract

The aim of the study was to evaluate antimicrobial activity of extract of Jengkol (Pithecellobium lobatum Benth.) and Petai (Parkia spesioca Hassk) peel as natural antimicrobial to inhibit Listeria monocytogenes. By using Minimum Inhibitory Concentration (MIC), the antimicrobial activity of Jengkol peel and Petai peel extract was 0.78 % and 0.39 %, respectively. By using Inhibition zone, the antimicrobial activity of Jengkol peel and petai peel extract was 1,08 ± 0,07 and 3,13 ± 0,13 mm. Phytochemical compounds of jengkol and petai were apigenin, coumaric acid, gallic acid, kaempferol, hesperidin, luteolin, naringenin, quercetin. Myricetin was found on jengkol but it was not found in petai peel extract. Antimicrobial activity of petai peel extract was more effective to inhibit Listeria monocytogenes than jengkol peel extract.
