The study used bitter almonds (Amygdalus communis L. Varietas amara D.C.) obtained by cold pressing medicinal nails grown in Navoi region using oil (Calendula officinalis L.) - with the participation of flowers, extraction process was carried out maceration (in a ratio 1:10). resulting extract studied its elemental composition, chromatographic analysis fatty acids, microbiological purity, chemi...

in order to comparing influence of ten vegetable oils for optimizing clodinafop-propargyl efficacy, a greenhouse experiment of dose-response including 0, 8, 16, 32, 48, and 64 g a.i. ha-1 of clodinafop-propargyl at eleven level of without vegetable oil and with vegetable oils of sunflower, soybean, canola, turnip, cotton, sesame, bitter almond, sweet almond, castor and olive in control of littl...

BACKGROUND Natural foods contain not only nutrients, but also nonnutritious and potentially harmful chemicals. Thus, animals need to evaluate food content in order to make adequate feeding decisions. RESULTS Here, we investigate the effects of acids on the taste neuron responses and on taste behavior of desirable, nutritious sugars and sugar/bitter compound mixtures in Drosophila melanogaster...

Molecular data suggest that receptors for all bitter ligands are coexpressed in the same taste receptor cells (TRCs) while physiological results indicate that individual TRCs respond only to a subset of bitter stimuli. It is also unclear to what extent bitter-responsive neurons are stimulated by non-bitter stimuli. To explore these issues, single neuron responses were recorded from the rat nucl...

The study investigates the therapeutic potential of Citrus aurantium var. amara essential oil extracted from blossoms bitter orange plant by examining its chemical composition, thermal stability, and potency against infectious disease-causing pathogens. Initially, volatile components were evaluated obtaining a chromatographic fingerprint using HPTLC FTIR spectrum identification. Furthermore, pr...

Most animals possess taste receptors neurons detecting potentially noxious compounds. In humans, the ligands which activate these neurons define a sensory space called "bitter". By extension, this term has been used in animals and insects to define molecules which induce aversive responses. In this review, based on our observations carried out in Drosophila, we examine how bitter compounds are ...

Two-bottle preference tests were done to determine whether pigs detect bitter-tasting compounds. Four standard bitter compounds and nine bitter-tasting pharmaceutical compounds were tested. Pigs detect and avoid taste compounds that humans perceive as bitter-tasting. A dose-response to varying concentrations of bitter tastants can be measured.
