In the present study the extracts of in vivo and in vitro grown plants as well as callus tissue of red clover were tested for their antioxidant activities, using different extraction solvent and different antioxidant assays. The total flavonoid and phenolic contents as well as extraction yield of the extracts were also investigated to determine their correlation with the antioxidant activity of...

Rutin is a phenolic compound and found in many plant species. Its name is derived from Ruta graveolens a plant that contain this compound. Rutin has many health benefits like it inhibits platelet aggregation, inflammation, hemorrhoid development etc. It is also used in dietary supplements of human beings for its health benefits. Therefore, this study was planned to investigate its other medicin...

Antioxidant activity of a selection of commonly occurring wild plants growing in Beni-Sueif governorate, Upper Egypt, has been tested. The plants selected are Tamarix nilotica, Ambrosia maritima, Zygophyllum coccenium, Conyza dioscoridis, Chenopodium ambrosioides, and Calotropis procera. The in vitro antioxidant assays used in this study were 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scaven...

A comprehensive in vitro study involving antiglycation, antioxidant and anti-diabetic assays was carried out in mature fruits of strawberry. The effect of aqueous extract of mature strawberry fruits on glycation of guanosine with glucose and fructose with or without oxidizing entities like reactive oxygen species was analyzed. Spectral studies showed that glycation and/or fructation of guanosin...

PURPOSE The aim of this study was to evaluate antioxidant ability of mangosteen shell and explore the non-enzymatic repair reaction and possible mechanism of xanthones in mangosteen shell. METHODS Mangosteen shell was extracted by methanol to obtain the extract of mangosteen shell. The extract was then determined by various antioxidant assays in vitro, including protection against DNA damage,...

Glutathione (GSH) is the classical example of a scavenging antioxidant. It forms the first line of defense and efficiently scavenges reactive species, e.g., hypochlorous acid (HOCl), before they inflict damage to biomolecules. Scavenging antioxidant activity is best established in competition assays (that closely mimics molecular mechanism of the biological effect). In this type of assay, the a...

The best described pharmacological property of flavonoids is their capacity to act as potent antioxidant that has been reported to play an important role in the alleviation of diabetes mellitus. Flavonoids biochemical properties are structure dependent; however, they are yet to be thoroughly understood. Hence, the main aim of this work was to investigate the antioxidant and antidiabetic propert...

The antidiabetic and antioxidant potential of ethanolic extract of Cassia nemophila pod (EECNP) was evaluated by three in vitro assays, including yeast glucose uptake assay, glucose adsorption assay, and DPPH radical scavenging activity. The result revealed that the extracts have enhanced the uptake of glucose through the plasma membrane of yeast cells. A linear increase in glucose uptake by ye...

Inside the human body, reactive derivatives of oxygen, known as reactive oxygen species (ROS) such as the superoxide radical (O2•), hydroxyl radical (•OH) and hydrogen peroxide (H2O2), are constantly generated. The ROS easily cause oxidative damage to various biomolecules such as proteins, lipids and DNA leading to various disease conditions. Iron chelators function as antioxidants by scavengin...

antioxidant activity of peucedanum pastinacifolium boiss. & hausskn aerial part hydroalcoholic extract (hae) and polyphenolic extract (ppe) as well as their total phenolic and flavonoid contents were studied. phenolic and flavonoid contents were respectively estimated as gallic acid and quercetin equivalents. the in vitro antioxidant activity of two extracts of p. pastinacifolium were evaluated...
