Gas chromatographic method for putrescine and cadaverine in shrimp.
A gas-liquid chromatographic method developed for the determination of putrescine and cadaverine in fishery products was modified for application to the determination of diamines in shrimp. Addition of potassium chloride and hydrochloric acid to the methanol-water extraction solvent resulted in increased recovery of the diamines and minimized gel formation. The recovery of putrescine increased ...
متن کاملIdentifying human diamine sensors for death related putrescine and cadaverine molecules
Pungent chemical compounds originating from decaying tissue are strong drivers of animal behavior. Two of the best-characterized death smell components are putrescine (PUT) and cadaverine (CAD), foul-smelling molecules produced by decarboxylation of amino acids during decomposition. These volatile polyamines act as 'necromones', triggering avoidance or attractive responses, which are fundamenta...
متن کاملGas-chromatographic Method for Volatile Congeners in Alcoholic Beverages Analysis
Alcoholic fermentation of fruits and cereals is the primary source of alcoholic beverages production. The main component in these drinks is ethanol; but there are also many secondary products like glycerin or acetaldehyde, and mixtures of other higher-order alcohols called “fusel”, also known as congeners. They are important for the characterization of alcoholic beverages and also for forensic ...
متن کاملSPECTROPHOTOMETRIC AND GAS CHROMATOGRAPHIC METHODS FOR DETECTION AND ASSAY OF MUSTARD GAS
A colorimetric method for detection and assay of mustard gas in urine after addition of thymolphthalein is reported. The detection limit was 80 ng/ml of llrine. Mustard gas could also be detected in urine after extraction with gas chromatography using FID detector. The detection limit was 10 ng/ml. In addition, thiodiglycol, a metabolite of mustard gas, could be converted to mustard with ...
متن کاملPresence of N-acyl and acetoxy derivatives of putrescine and cadaverine in the human gut.
N-acyl and acetoxy derivatives of putrescine and cadaverine have been found in the faeces of children and in cultures of isolates of gut bacteria. The evidence was accumulated from two dimensional, thin layer chromatography, field desorption mass spectrometry, and accurate mass measurement of the DANS derivatives of the amines. The acetoxy compounds of putrescine and cadaverine have not previou...
