متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
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...
