gas chromatography, gc/mass analysis and bioactivity of essential oil from aerial parts of ferulago trifida: antimicrobial, antioxidant, ache inhibitory, general toxicity, mtt assay and larvicidal activities

Background: we aimed to investigate different biological properties of aerial parts essential oil of ferulago trifida boiss and larvicidal activity of its volatile oils from all parts of plant. methods: essential oil was prepared by steam distillation and analyzed by gas chromatography and gc/mass. anti-oxidant, antimicrobial, cytotoxic effects and ache inhibitory of the oil were investigated using dpph, disk diffusion method, mtt assay and ellman methods. larvicidal activity of f. trifida essential oil against malaria vector anoph-eles stephensi was carried out according to the method described by who. results: in gc and gc/ms analysis, 58 compounds were identified in the aerial parts essential oil, of which e-ver-benol (9.66%), isobutyl acetate (25.73%) and e-β-caryophyllene (8.68%) were main compounds. the oil showed (ic50= 111.2μg/ml) in dpph and ic50= 21.5 mg/ml in the investigation of ache inhibitory. furthermore, the oil demonstrated toxicity with (ld50= 1.1μg/ml) in brine shrimp lethality test and with (ic50= 22.0, 25.0 and 42.55 μg/ml) on three cancerous cell lines (mcf-7, a-549 and ht-29) respectively. lc50 of stem, root, aerial parts, fruits, and flowers essential oils against larvae of an. stephensi were equal with 10.46, 22.27, 20.50, 31.93 and 79.87ppm respectively. in antimicrobial activities, essential oil was effective on all specimens except escherichia coli, asper-gillus niger and candida albicans. conclusion: the essential oil showed moderate antioxidant activity, strong antimicrobial properties and good toxic effect in brine shrimp test and mtt assay on three cancerous cell lines.
