Fluorometric determination of phenylpyruvic acid with 1,4-dimethyl-3-carbamoylpyridinium chloride.
A fluorometric method for the determination of phenylpyruvic acid (PPA) has been established. Benzaldehyde formed from PPA by alkaline decomposition is quantified by means of its fluorogenic reaction with 1,4-dimethyl-3-carbamoylpyridinium chloride. PPA can be determined in the range of 0.1-3 nmol/50 ƒÊl with the relative standard deviation of 4.0-4.1%. About 70% recovery was obtained when a ur...
متن کاملFluorometric determination of histidine.
A. FLUOROMETRIC METHOD for the determination of histidine was developed in response to the need for an accurate and precise manual method for the confirmation of histidinemia (1). it is based on the fluorometric method of Shore et a!. (2), which involves the condensation of histaniine with o-phthalaidehyde (OPT) in a strongly alkaline solution to form a rather labile fluorescent compound which ...
متن کاملFluorometric determination of propoxyphene.
With 4-chloro-7-nitrobenzo-2, 1,3-oxadiazole (I), fluorescent derivatives of propoxyphene can be prepared, thus enabling quantitation of the drug in biological samples. This technique offers an acceptable alternative to gas chromatographic (1-5) or ultraviolet spectrophotometric (6, 7) procedures. Favorable aspects of the fluorometric technique are high sensitivity, specificity, potential for r...
متن کاملFluorometric determination of carbohydrate with 2-aminothiophenol.
The 2-aminothiophenol-based fluorometric assay of Nakano et al. (1973, J. Pharm. Soc. Jpn. 93, 350-353) for monosaccharides has been modified to improve the speed, applicability, and sensitivity of the method. The improved assay is applicable to complex carbohydrates as well as to monosaccharides. Less than 50 ng of carbohydrate in a final volume of 2 ml can be quantitatively measured within 30...
متن کاملImproved fluorometric determination of malonaldehyde.
Lipoperoxidation is implicated in various pathological conditions. Malonaldehyde (MDA) is the most commonly used marker of this process. We propose simple modifications to Yagi's fluorometric assay for MDA determinations, to avoid long and tedious manipulations by eliminating the first precipitation and washing steps, analogous to HPLC methods, and to increase both the sensitivity and the speci...
