The objective of this study was to characterize the antioxidant properties of ethanol extracted from leaves of Jatropha curcas and to determinate the compounds. The IC50 values of DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt) were found to be 7.47 and 6.6 μg/ml, respectively, for the extracts. The reducing power of the ex...

This study aimed to evaluate and correlate phytochemical content, antioxidant activity alpha-amylase inhibitory in aqueous acetone extract fractions derived from it (ethyl acetate fraction, watersoluble methanol fraction fraction) which are obtained Ampelocissus martini Planch. root. Ethyl had the highest total phenolic content proanthocyanidin respectively. 2,2-diphenyl-1-picrylhydrazyl, 2,2'-...

In the present work, optimization of pectinase-assisted and tri-solvent-mediated extraction of lycopene from waste tomato peels was carried out. The optimized parameters for enzymatic pre-treatment were 2% pectinase concentration, pH 5.5, 4-h incubation, 45 °C and 150 rpm. Maximum recovery of lycopene from tomato peels using optimized tri-solvent extraction was achieved at 45 °C, 120-min incuba...

The object of this research was the beetroots prepared by intermittent microwave drying at different conditions. paper aimed to investigate influence conditions (power density, gap ratio and slice thickness) on bioactive compounds antioxidant capacity beetroots. A system SAM-255 (CEM Corporation, USA) used fresh effect power densities (1.0, 1.5, 2.0, 2.5 W/g), ratios (1, 2, 3, 4) thicknesses (2...

The bioactive compounds and antioxidant activity of aronia leaves at different stages of maturity were identified and evaluated. Young and old leaves were approximately 2 months of age and 4 months of age, respectively. The young leaves contained more polyphenols and flavonoids than the old leaves. Three phenolic compounds (i.e., chlorogenic acid, p-coumaric acid, and rutin) were detected by HP...

The valorization of food processing by-products, wastes and effluents is a challenging opportunity for the sustainable and competitive development of several relevant industrial sectors. One of the best examples of a biorefinery applied to plant processing wastes is that of the olive oil sector by-products including leaves and olive mill wastewaters (OMW). Management of OMW, in particular, has ...

Many medicinal plants have been reported to exhibit protective effects against many physiological diseases as a result of their phytochemical components which are effective antioxidants. This study was aimed at comparing the phenolic and flavonoids contents, antioxidant cytotoxic activities methanol extract Jatropha curcas seeds leaves. The cytotoxicity level J. assessed using brine shrimp leth...

A fully automated flow-injection immunoassay based on sandwich enzyme-linked immunosorbent assay (ELISA) is described for the model system: protein G-sepharose, rabbit IgG and horseradish peroxidase (HRP)-labelled protein A. After injecting rabbit IgG and HRP-labelled protein A into a cartridge containing protein G-sepharose sequentially, a mixture of hydrogen peroxide and the redox indicator, ...

Testas of Cola fruit are usually considered as agricultural waste by many farmers their focus is always on the seed because its economic importance. This study therefore aimed at evaluating and comparing antioxidant potentials C. acuminata nitida testas. The methanol extract testas were evaluated compared for properties such as: scavenging abilities hydroxyl radicals, ABTS (2, 2– Azino-bis-3-et...

MZ: Meso-Zeaxanthin; L: Lutein; RZ: RR-Zeaxanthin; AMD: Age-related Macular Degeneration; MD: Macular Degeneration; NAFL: Non-Alcoholic Fatty Liver; NASH: Nonalcoholic Steatohepatitis; DPPH: Diphenyl-2-Picrylhydrazyl; ABTS: 2, 2’-Azino-Bis (3-Ethylbenzothiazoline-6-Sulfonic acid); GST: Glutathione-S-Transferase; UDPGT: Uridine Diphosphate Glucuronyl Transferase; SGOT: Serum glutamic oxaloacetic...
