Abstract:
The aim of this study is to determine the physicochemical properties and antimicrobial activity of the oil from Trigonellafoemnum-graecum.
The oil yield was (37%). The physicochemical presents that moisture was (1.75%), refractive index at (30°C) (1.4743), density (0.855g/cm3), saponification value (0.2mg KOH/g), peroxide value (0.5mg O2/100g) and acid value was (3.4mg KOH/g).
GC-MS analysis shows that the dominant fatty acids are (9.12) Octadecadienoic acid (Z, Z) methyl ester (43.48%), 9, 12, 15- Octadecatrienoid acid, methyl ester, (Z, Z, Z) (20.15%), Hexadecanoic acid, methyl ester (16.35%) and Stearic acid (8.77%).
The oil shows antimicrobial activity against Candida moderate.
Significant activity against gram Positive Staphylococcus aureus, Bacillus subtilis and gram-negative Escherichia coli and Pseudomonas aeruginosa.
