Keywords : Seinat seeds, essential oil, GC-MS, antibacterial activity.



ABSTRACT: The chemical composition of the essential oil constituent from Seinat (Cucumis melo var. tibish) seeds was analyzed by gas chromatography-mass spectrometry (GC-MS). Forty components were identified; with 9, 12-Octadecadienoic acid, methyl ester (15.27%), 2H-Pyran-2-one, tetrahydro-6-nonyl (14.60%) being the main constituents in the essential oil. Based on their functional groups, the ester compound group was highest content (31.20%) compared with the other groups. In vitro antibacterial activity against three strains of Gram-positive bacteria and three strains of Gram-negative bacteria was studied. The essential oil of seinat seeds had pronounced antibacterial activity on all the tested bacteria. Minimum inhibitory concentration (MIC) was in the range from 0.5 to 5 mg/mL of sample.
