In the present study, a simple and sensitive methodology based on dynamic headspace solid-phase microextraction (HS-SPME) followed by thermal desorption gas chromatography with quadrupole mass detection (GC-qMSD), was developed and optimized for the determination of volatile (VOCs) and semi-volatile (SVOCs) compounds from different alcoholic beverages: wine, beer and whisky. Key experimental fa...
The volatile compounds released by orthodox (desiccation-tolerant) seeds during ageing can be analysed using gas chromatography-mass spectrometry (GC-MS). Comparison of three legume species (Pisum sativum, Lathyrus pratensis, and Cytisus scoparius) during artificial ageing at 60% relative humidity and 50 °C revealed variation in the seed volatile fingerprint between species, although in all spe...
many medical properties including antimicrobial, anticancer, antioxidant, anti-inflammatory, etc. have been mentioned for Viola odorata. results have shown the solid cell-killing effects of Viola odorata cycloidal compounds. In addition, Pathogen resistance has necessitated the study of new antimicrobial compounds. This study aimed to evaluate the antimicrobial and anticancer effects of aqueous...
A series of new 6-amino-4aryl-2’-[(4-Aminophenyl)thio]-2,4’-bipyridine-5-carbonitriles (3a-h) were synthesized from 4-aminothiophenol (1). The reaction of 4-aminothiophenol with 4-acetyl-2-chloropyridine yielded 1-{2-[(4-aminophenyl)thio]pyridin-4-yl}ethanone(2).Furthertreatment of 2 with aromatic aldehydes in the presence of alcoholic malanonitrile in ammonium acetate gave compounds (3a-h). T...
Rhipicephalus annulatus (Acari: Ixodidae) Control by Nigella sativa, Thyme and Spinosad Preparations
BACKGROUND Several compounds obtained from plants have potential insecticidal, growth deterrent or repellent characteristics. The control of hard ticks by non-chemical substances was targeted in this study. METHODS The effect of 36 materials on in-vitro ticks was studied, including 2 absolute controls (water only or absolute ethyl alcohol only), 6 conventionally used spinosad preparations (aq...
Alcoho1ic beverages are produced from raw materials by fermentation. The predominant types of commercially produced alcoholIc beverages are beer, wine and spirits. The main components of all alcoholic beverages are ethanol and water; beers also contain substantial amounts of carbohydrates. Many compounds that have been identified as common to alI alcoholic beverages are present in different qua...
ferula gummosa boiss is a good source of biologically active compounds such as monoterpene and sesquiterpene derivatives. there are also several reports on antioxidant effects of these compounds. the aim of this study was to investigate the effect of daily administration of f. gummosa root hydro-alcoholic extract on serum oxidant-antioxidant status. twenty four wistar rats were randomly divided...
Alcoholism is highly prevalent among bipolar disorder (BD) patients, and its presence is associated with a worse outcome and refractoriness to treatment of the mood disorder. The neurobiological underpinnings that characterize this comorbidity are unknown. We sought to investigate the neurochemical profile of the dorsolateral prefrontal cortex (DLPFC) of BD patients with comorbid alcoholism. A ...
The biochemical compounds of red raspberry (Rubus idaeus L.) fruits cultivated with conventional growing technology and on a nutrient substrate were studied during 2019–2020 at the Federal Horticultural Research Center for Breeding, Agrotechnology Nursery, Moscow, Russia. antioxidant activity, phenolic compounds, ash constituents metabolites alcoholic extract raspberries determined. effect tech...
Background & Objective: Food poisonings caused by consumption of domestic dairy products such as cheese due to Escherichia coli (E.coli) and Staphylococcus aureus (S.aureus) are one of the hygienic problems in foodstuffs. Nowadays, using natural preservatives instead of synthetic preservatives in foods has been regarded increasingly and among these natural compounds, medicinal plants comprise t...
