Phthalocyanine complexes of Cu, Co, Ni, Fe, Zn, Pd, Pt and Ru have been synthesized from reaction between phthalonitrile and proper metal salts upon exposure to microwave irradiation under solvent-free conditions and considerably reduced reaction times.

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...

Nordihydroguaiaretic acid (NDGA) is a powerful antioxidant with biological activities of great interest in several health areas, including antiviral, cancer chemopreventive, and antitumorgenic. Little information is available on extraction methods of NDGA from Larrea tridentata. Hence, the aim of this study was to develop a rapid and effective microwave-assisted extraction (MAE) method for NDGA...
