چکیده

black zira (bunium persicum) is a medicinal plant and spice, naturally grows in iran. the aim of this study was to investigate the combined effects of different concentrations of bunium persicum essential oil (eo; including 0, 0.08, 0.16 and 0.24%), three incubation temperatures (15, 25 and 35˚c), three levels of ph (5, 6 and 7 adjusted by hydrochloric acid), and three inoculum size (102, 103 and 104 cfu ml-1) on the growth of staphylococcus aureus in the brain heart infusion broth. black zira eo was extracted and its component was identified using gas chromatography-mass spectrometry (gc-ms) analyses. the experiment was carried out in triplicate. growth was monitored by visible turbidity during a 30-day period. to evaluate effects of explanatory variable on time to detection (ttd) of bacterial growth, parametric survival models based on log-normal distribution was used. all explanatory variables had significant association with time to detection (p < 0.05). the final model accurately predicted the growth initiation and inhibition of s. aureus.

antioxidant activity of essential oil from black zira (bunium persicum boiss.) obtained by microwave-assisted hydrodistillation

microwave-assisted hydrodistillation (mahd) at three levels of microwave power (180, 360, and 540 w) and the traditional hydrodistillation (hd) were applied to obtain essential oils from bunium persicum boiss. (black zira). mahd at 540 w started much earlier than that of hd (4 min vs. 38 min, respectively). by the time the extraction of essential oils started with hd, almost 50% of the total es...
