Antioxidants can either stop or slow down the excessive oxidation of a compound. This study aimed to determine the secondary metabolite compounds, antioxidant activity, total flavonoid and phenolic levels, and the correlation between the levels of flavonoid and phenolic compounds in inhibiting free radicals.

This research investigates the chemical composition, total phenolic and flavonoid content, and antioxidant activity of acetone, methanol, and ethanol extracts of the lichen Umbilicaria grisea, and its major secondary metabolite, gyrophoric acid. The extracts were analyzed using high-performance liquid chromatography (HPLC-UV) and spectrophotometric assays. The results showed significant levels of phenolic compounds and flavonoids, which contribute to the lichen’s antioxidant potential. The antioxidant activity was evaluated using in vitro assays such as DPPH and ABTS radical scavenging activit

Abstract:
The aim of this paper is to determine the content of selected phenolic compounds and to find the appropriate optimal extraction agent for the extraction of phenolic compounds from the plant species Iris pumila L. The content of total phenols and flavonoids in the rhizome and aboveground parts of the plant was determined by the application of the spectrophotometric method in the examined extracts obtained by the maceration method. By comparatively analyzing the application of two solvents for extraction, we concluded that the application of methanol in the conventional maceration technique cont

Abstract:
Olive leaves (OL) are considered a potential source of bioactive compounds mainly due to its high content of polyphenols, widely known as natural antioxidants. The objective of this study was to optimize supercritical fluid extraction conditions from OL in order to obtain natural extracts with high antioxidant activity. OL (belong to the Arbequina cultivar) were collected from a local producer (Uruguay) and subjected to a drying and milling (1 mm particle size) pre-treatment. Supercritical fluid extractions were carried out using a laboratory-built system equipped with a 25 mL stainless steel

Abstract:
Phenolics found in various crops and by-products have antioxidant and antimicrobial activities and their consumption have been associated with health benefits. For example, a by-product of the cranberry juice industry is cranberry pomace, which is considered a rich source of anthocyanins. Research in my laboratory has focused on the use of pressurized fluids to extract these phenolic compounds to be used in various applications. Pressurized fluids, such as subcritical water, pressurized ethanol and supercritical CO2 (SC-CO2) as “green” and environmentally friendly solvents, can be used for

This research was aimed to develop an active film from chitosan film incorporated with green tea extract to enhance antioxidant and antimicrobial properties in order to be used for food shelf life extension. The experiments were divided into 3 parts. Firstly, chitosan-based film preparation and modification were determined. The results suggested that the optimum chitosan films could be prepared from 2% chitosan in 1% acetic acid. However, the chitosan film was brittle and had low flexibility. Mechanical property of chitosan film was modified by adding different concentrations of glycerol, as a

The antioxidant reaction of flavonoids found in red wines against lipid peroxidation were found to depend on the structure of the molecule.

Our study was designed to elucidate the chemical determinants of pectin cross-linking in developing fruits of apple and peach and to evaluate the role of breakage cross-linkages in swelling, softening, and cell separation during the ripening. Peaches cell walls soften and swell considerably during the ripening, whereas apples fruit cells maintain wall firmness but cells separate during late stages of ripening. We used a "double-reduction" technique to show that levels of non-methyl esters of polyuronic acid molecules were constant during the development and ripening and decreased only in overr
