Aplicação

1,3-Diethyl-2-thiobarbituric acid (DETBA) was used as coinitiator during the photopolymerization of dental materials. It was used as reagent in electrochemical oxidation of 3,4-dihydroxybenzoic acid to yield benzofuro[2,3-d]pyrimidine derivatives. It was used in DETBA assay for determination of nicotine metabolites in human urine by HPLC.

Effect of selenium enrichment on antioxidant activities and chemical composition of Lentinula edodes (Berk.) Pegl. mycelial extracts.

Jadwiga Turło et al.

Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association, 48(4), 1085-1091 (2010-02-09)

Preparations derived from Lentinula edodes (Berk.) Pegl. mycelium are worldwide used as dietary supplements containing compounds active as immune system enhancers, demonstrating chemopreventive and anticancer activity. L. edodes mycelium enriched with organic forms of selenium like selenized yeast possess putative

Peroxyoxalate chemiluminescence detection of condensates of malondialdehyde with thiobarbituric acids using a flow system.

K Nakashima et al.

Biomedical chromatography : BMC, 6(2), 55-58 (1992-03-01)

The peroxyoxalate chemiluminescence(CL) detection method for the evaluation of the CL intensity of malondialdehyde(MDA) condensates with seven 2-thiobarbituric acid derivatives is described. The method consists of a flow injection technique together with a CL detection system using bis(2,4,6-trichlorophenyl) oxalate(TCPO) and

A simple, inexpensive urine test of smoking.

H Peach et al.

IARC scientific publications, (74)(74), 183-193 (1986-01-01)

Three novel colorimetric methods of detecting urinary nicotine metabolites called the barbituric acid, diethylthiobarbituric acid (DETB) and DETB-extraction methods were evaluated for use as a simple cheap objective test of smoking. Urine samples were collected from 103 male smokers and

High-performance liquid chromatographic determination of 1,3-diethyl-2-thiobarbituric acid--malonaldehyde adduct in fish meat.

T Sakai et al.

Journal of chromatography. B, Biomedical sciences and applications, 726(1-2), 313-316 (1999-05-29)

The reaction conditions of 1,3-diethyl-2-thiobarbituric acid (DETBA)-malonaldehyde (MA) adduct formation were examined in order to analyze MA in fish tissue by high-performance liquid chromatography. A reaction mixture containing 4 mM butyl hydroxytoluene was heated at 100 degrees C for 150

Assessment of simple colorimetric procedures to determine smoking status of diabetic subjects.

R F Smith et al.

Clinical chemistry, 44(2), 275-280 (1998-02-25)

The performance of a simple colorimetric assay for urinary nicotine metabolites to assess smoking status in diabetic subjects (n = 251) was investigated. Several variations of the colorimetric assay and a qualitative extraction procedure were evaluated in comparison with a
