ABSTRACT:The volatile oil hydrodistilled from leaf, stem, fruit and root of Duranta repens were investigated for their chemical constituents, antioxidant and antimicrobial activity using GC-MS techniques, DPPH radical-scavenging assay and agar-diffusion method respectively. A total of 30, 12, 20 and 35 constituents were identified in the leaf, stem, fruit and root oils corresponding to 92.5%, 99.5%, 95.1% and 92.2% of the whole volatile oil respectively. Palmitic acid (55.7%, root), styrene (52.5%, fruit), p-vinylanisole (26.0%, fruit) and tetracosane (22.2%, stem) were the prominent components identified in the oils. The fruit and stem oils displayed good DPPH free radical-scavenging activity with IC50 value of 29.39µg/mL and 32.02µg/mL respectively, when compared with that of synthetic antioxidants α-tocopherol (81.58µg/mL) and BHA (45.11µg/mL). The oils showed low antibacterial activity and moderate antifungal activity against the test pathogens with inhibition zone diameter (IZD) range between 2.0±0.0 and 8.5±0.5 mm, lower than the reference compounds gentamycin and ketoconazole (IZD range 9.0±1.4-21.0±1.4 mm). The chemical constituents, antifungal potential and DPPH radical scavenging activity of Duranta repens volatile oils suggest they can act as an adjuncts in lubricant, food, cosmetic and medicine.
