This study concerns the transformation of maritime pine (Pinus pinaster) sawdust waste into potentially novel products through isolation of volatile compounds in the form of valuable oil. Different techniques, namely, turbohydrodistillation (THD), solvent-free microwave extraction (SFME), microwave hydrodiffusion and gravity (MHG), and ultrasound-assisted extraction (UAE) were tested. These dif...

Porous agar materials have been prepared from marine macroalgae species using a simple microwave-assisted extraction/drying methodology, providing a new family of polysaccharide derived porous solids. The microwave-assisted extraction allows a more efficient and less time-consuming extraction of the polysaccharide compared to conventional extraction protocols based on conventional heating. DRIF...

the essential oils obtained by hydrodistillation (hd), steam distillation (sd) and solvent free microwave extraction (sfme) from the stems and flowers of tanacetum tenuisectum (boiss.) podl., which is endemic to iran,were analyzed by gc and gc/ms.camphor (26.9 %, 27.2% and 25.5%), borneol (12.6%, 11.5% and 7.6%) and 1, 8-cineole (7.9%, 13.2% and 11.3%) were the main constituents of the hd, sd a...

as traditional extraction methods like hydrodistillation (hd) and steamdistillation (sd) have long extraction times, some novel extraction methods like microwave-assisted hydrodistillation (mahd) and ohmic-assisted hydrodistillation (oahd) are recently introduced. in this study, essential oils of mentha piperita were extracted by oahd and mahd and the results were compared with those of the sd ...

BACKGROUND Currently, there is an increasing interest in developing more efficient techniques for the extraction of phytochemicals. Microwaves and ultrasonic extraction methods are promising techniques that can be used for this purpose. OBJECTIVES The purpose of this study was to investigate the impact of different extraction methods on yield, antioxidant and antimicrobial activities of volat...
