Modified method for the determination of pyruvic acid with dinitrophenylhydrazine in the assessment of onion pungency
Modifications to the commonly used Schwimmer and Weston procedure for determining pyruvic acid in onions are proposed. These modifications involve changes in the concentrations and volumes of the reagents and the use of 515 rather than 420 nm as the wavelength for measurements. These changes improve both the linearity and the sensitivity of the assay and eliminate interference from coloured mat...
متن کاملThe Crystallographic, Spectroscopic and Theoretical Studies on (E)-2-[((4-fluorophenyl)imino)methyl]-4-nitrophenol and (E)-2-[((3-fluorophenyl)imino)methyl]-4-nitrophenol Compounds
In this study, two new salicylideneaniline derivative compounds which are an isomer of each other have been synthesized and characterized by X-Ray Diffraction (XRD) technique, IR spectroscopy, and theoretical method. While (E)-4-(dihydroxyamino)-2-(((4-fluorophenyl)imino) methyl)phenol (1), crystalizes triclinic P-1 space group, (E)-4-(dihydroxyamino)-2-(((3-fluorophenyl)im...

Studies on uric acid and related compounds. I. Quantitative determination of uric acid in biological fluids.
The available methods of determination of uric acid can be divided into three main groups: (a) the direct determination of the reducing power of uric acid; (b) the coprecipitation of the uric acid or its adsorption on a precipitating material, dissolving the acid, and determination of its reducing power; and (c) quantitative decomposition of uric acid by uricase. A survey of these methods has b...
