Considerable evidence suggests that mitochondrial dysfunction contributes to the toxicity of uranyl acetate (UA), a soluble salt of depleted uranium (DU). We examined the ability of the two antioxidants, beta-glucan and butylated hydroxyl toluene (BHT), to prevent UA-induced mitochondrial dysfunction using rat-isolated kidney mitochondria. Beta-glucan (150 nM) and BHT (20 nM) attenuated UA-indu...

The fruits of Heracleum aquilegifolium Wight (Apiaceae) were collected from Western Ghats of the Indian Peninsula. The essential oils were extracted by hydrodistillation. The chemical composition of the essential oils was analysed by gas chromatography and gas chromatography-mass spectrometry (GC-MS). Beta-Pinene (22.3%), 1,8-cineole (20.3%), and beta-phellandrene (12.4%) were the main componen...

Background: Nowadays, natural antioxidants are used to replace synthetic antioxidants for delaying or preventing the oxidation of edible oils. In this study, phenolic compounds and antioxidant properties of methanol extracts of Spirulina microalgae (Arthrospira platensis) were measured. Methods: Phenolic content was measured by Folin–Ciocalteau method and antioxidant activity was measured by th...

Current approaches to achieve site selectivity in the C-H activation of arenes involve the use of directing groups or highly electron-poor arenes. In contrast, simple arenes, such as anisole, are characterized by poor reactivity and selectivity. We report that π-complexation to a Cr(CO)3 unit enhances the reactivity of anisoles providing an unprecedented ortho-selective arylation. This mild met...

In the title compound, C(29)H(21)BrF(2)O(3), the dihedral angles between the central anisole ring and the pendant fluoro-benzene rings are 48.86 (19) and 31.89 (18)°. The dihedral angle between the anisole ring and the 1-bromo-2-meth-oxy-benzene ring linked via the enone bridge is 82.95 (17)°. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into C(11) chains propagating along [010].

Wheat bran was destarched and deproteinated by a-amylase, protease and amyloglucosidase successively, and further hydrolyzed using Bacillus subtilis xylanases. The yield of enzymatic hydrolysates from wheat bran (EHWB) was 1.84 %. The total phenolics were 0.3712 g of ferulic acid equivalents per gram of EHWB. The antioxidant potency of EHWB was evaluated using different assays, such as iron ion...

Abstract Background Eremomastax speciosa (Hochst.) Cufod. ( Acanthaceae ) is a renowned medicinal plant used to ease menstrual cramps and treat female infertility, anaemia, dysentery, urinary tract infection haemorrhoids. Essential oils their constituents from herbs have also been utilised in the management of good number ailments ethno-medicine. The chemical composition, antioxidant antimicrob...

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...
