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...
Exposure to carbofuran and fenamiphos for 72 hours reduced the numbers of active Aphelenchus avenae in aqueous suspension by > 75%. When nematicides were removed, many A. avenae exposed to carbofuran resumed normal movement but A. avenae treated with fenamiphos did not recover. Acetylcholinesterase (AChE) activity was suppressed by > 95% in nematodes treated with carbofuran or fenamiphos. Howev...
A variety of selenium compounds were proven to be useful reagents and catalysts for organic synthesis over the past several decades. The most interesting aspect, which emerged in recent years, concerns application of hydroperoxide/selenium(IV) oxide and hydroperoxide/organoselenium catalyst systems, as "green reagents" for the oxidation of different organic functional groups. The topic of oxida...
Introduction Organotin compounds (OTs) are ubiquitous contaminants used as PVC stabilizers, antifouling biocides, agricultural pesticides and catalysts for the production of polyurethanes and silicones 1 . Despite broad range of applications, their notoriety is due to the outstanding biocidal properties of triorganotin derivatives, particularly tributyltin (TBT), used for decades as an active i...
Background and purpose: Diazinon is an organophosphate insecticide that binds to the acetylcholinesterase enzyme after metabolization causing its inactivation. Galic acid is a polyphenolic compound with nucleophilic properties. The aim of this study was to investigate the effects of gallic acid on reactivation of acetylcholine and butyrylcholinesterase inhibited by diazinon in mice and human se...
