Mango seed kernel (MSK) extract contains phytochemicals, bioactives, and fatty acids that are of interest to food nutritional scientists. The subcritical water extraction process (SCWE) can be effective in extracting valuable bioactives from MSK. In this study, SCWE was investigated optimized for the MSK using Box–Behnken experimental design. yield examined as a function various variables, name...

This study was designed to evaluate, for the first time, antioxidant and antimicrobial activities of Nepeta × faassenii essential oil (NEO). Twenty-six compounds were identified by gas chromatography mass spectrometry analysis, which 4a alpha,7alpha,7a alpha-nepetalactone (34.12%), elemol (23.23%), spiro(5,6)dodecane (13.73%), 3,4 alpha-dihydro-4a alpha, 7 7a (7.93%) major compounds. The NEO ex...

The second-order rate constants for the microbial transformation of a series of phenols were correlated with the physicochemical properties of the phenols. The compounds studied were phenol, p-methylphenol, p-chlorophenol, p-bromophenol, p-cyanophenol, p-nitrophenol, p-acetylphenol, and p-methoxyphenol. Phenol-grown cells of Pseudomonas putida U transformed these compounds. Microbial transforma...

To clarify whether polyamines scavenge alkyl (carbon-centered) and peroxy (oxygen-centered) radicals, we analyzed their effects on the kinetics of polymerization of methyl methacrylate (MMA) induced by 2,2'-azobisisobutyronitrile (AIBN, a R* radical) and benzoyl peroxide (BPO, a PhCOO* radical) under nearly anaerobic conditions. Stoichiometric factors (n; number of free radicals trapped by one ...

A flow-through optosensor with solid phase UV spectroscopic detection is proposed for the direct determination of single antioxidants, namely butylated hydroxyanisole (BHA) and n-propyl gallate (n-PG), without previous derivatization. The methods are based on the transient retention behaviour of these compounds in a flow-through cell packed with C-18 silica using ethanol-water mixtures as a car...
