gallic acid mass spectrum


Gallic acid is a phenolic compound also known as 3,4,5-trihydroxybenzoic acid. Gallic Acid, Monohydrate, Crystal, Reagent, ACS, also known as 3,4,5-trihydroxybenzoic acid, can be used as a starting material in the synthesis of the psychedelic alkaloid mescaline. It is found both as a free state and as a constituent of tannins, namely, gallotannin. 3,4,5-Trihydroxybenzanilide. It is commonly used in the pharmaceutical industry. Gallic acid and its derivatives are present in nearly every part of the plant, such as bark, wood, leaf, fruit, root, and seed. The exact position of this broad band depends on whether the carboxylic acid is saturated or unsaturated, dimerized, or has internal hydrogen bonding. Our results suggest CAS contains polyphenols with strong α-amylase inhibitory activity. The fragment of the [M-H-CO 2 ] − ion at m/z 125 was shown in the MS–MS experiment. Gallic acid chloride was synthesized by the dropwise addition, over a period of 0.25hr, of 3.16ml (44.3mmol) of thionyl chloride to a solu-tion of 5.03g (29.6mmol) of gallic acid and three drops of dimethylformamide in 20ml of anhydrous tetrahydrofuran (THF) maintained near … Ellagic acid, gallic acid and punicalagin A&B potentially inhibited LPS-induced NO, PGE-2 and IL-6 production. In TLC, standards of catechin and Gallic acid were also used (gallic acid, Rf 0.88; catechin, Rf 0.86) [27]. The molecular structure of gallic acid and catechin were predicted in Fig. After 18 h treatment with Gallic acid, the number of viable neutrophils is dramatically decreased from 40.3% to 27.7%, highly comparable with 26.4% for untreated neutrophils. It is highly specific for gallic acid. 3,4,5-Trihydroxybenzoic acid monohydrate.

In the present work, gallic acid as a trapping agent of blood formaldehyde was investigated by liquid chromatography/tandem mass spectrometry (LC/MS/MS) and neutral loss scan. Reference data were obtained primarily from the PubChem database.. Three dimensional molecular rendering uses Jmol.. InChI string and atom numbering calculated using ALATIS (Hesam Dashti, William M. Westler, John L. Markley, Hamid R. Eghbalnia, "Unique identifiers for small molecules enable rigorous labeling of … Gallic acid glycoside was enzymatically synthesized by using dextransucrase and sucrose from gallic acid. Spectrum analysis showed the same Rf values and spectrum pattern of standard and sample. In our work, the gallic acid, which was produced by the hydrolysis of BG, proved to undergo further metabolic reactions including O-methylation and … Based on the previous studies on its metabolic fate, gallic acid will be metabolized through decarboxylation, O-methylation, sulfation, and glucuronidation reactions in rats [18, 19]. Gallic acid monohydrate. The results indicate that ellagic acid, gallic acid and punicalagin may be the compounds responsible for the anti-inflammatory potential of P. granatum. Communication and Mass Media - ... method for analysis of Gallic acid gallic acid Subject Category: ... methanol: formic acid (3: 3: 0.2: 0.8 v/v) system was developed as a mobile phase. The fatty acid composition was identified by a mass spectrum database (NIST Library, mass spectral search program, version … as eluent, toluene-acetone-formic acid (3:6:1), and the plates were developed with UV light (254 nm and 365 nm), vanillin, iron chloride and an iodine chamber to establish the composition of the fractions. ... Mass spectrum showing the presence of ellagic acid [M-H] -m/z 301. 95 Gallic acid has been shown to effectively … CAS=121-79-9, Molecular Formula=C 10 H 12 O 5, Molecular Weight (g/mol)=212.2, MDL Number=MFCD00002196, InChI Key=ZTHYODDOHIVTJV-UHFFFAOYSA-N, Synonym=propyl gallate,n-propyl gallate,progallin p,tenox pg,nipagallin p,gallic acid, propyl ester,gallic acid propyl ester,nipa 49,benzoic acid, 3,4,5-trihydroxy-, … The temperature of the mass spectrometer (MS) source, MS quadrupole, and the transfer line into the MS were 230, 150, and 280°C respectively. 72 mass spectra in 1 spectral trees are available online for the compound Gallic acid . 2.4.1. Go To: Top, Mass spectrum (electron ionization), Gas Chromatography, References Data from NIST Standard Reference Database 69: NIST Chemistry WebBook The National Institute of Standards and Technology (NIST) uses its best efforts to deliver a high quality copy of the Database and to verify that the data contained therein … 4. Gallic acid is found both free and as part of tannins. This is consistent with three hydrogens providing hyperfine splitting. 5995-86-8. The data also suggest CAS … In addition to quercetin, the presence of gallic acid, Gallic acid was isolated from EtOAc by another method previously reported by Ben Saad and Kim, 2015 . 11 (2) 2016 Singh et al. Limits of detection were 1.42 and 1.56 μg mL-1 and limits of quantification were 4.32 and 4.73 μg mL-1 for ascorbic and gallic acid, respectively. 50 μl volumes of … O–H stretch from 3300-2500 cm-1; C=O stretch from 1760-1690 cm-1; C–O stretch from 1320-1210 cm-1; O–H bend from 1440-1395 and 950-910 cm-1; Figure 11. shows the spectrum of hexanoic acid … The developed method was quite good and most … Phenolic compounds (delphinidin and gallic acid), at concentrations that encompassed the physiologically relevant range (10 nM–100 μM), were prepared in tissue culture medium prior to addition of Tempone-H (10 mM stock, dissolved in ultrapure water) to generate a final concentration of 2 mM. The air-oxidation of gallic acid at near-neutral pH produces a semiquinone free radical that is easily observed by electron paramagnetic spectroscopy (EPR), Figure 1.This spectrum appears as a doublet of triplets and consistent with hyperfine splittings by three protons having hyperfine splitting constants of 1.00 G, 0.23 G, … For mass detection 0.7 ml/min of pH program, version spectrum showing the presence of gallic fails...
