Cadmium (Cd) contamination is a highly dangerous international problem because it can transfer into the food chain and become bioaccumulated, endangering human health. Cd detoxication is very interesting particularly the method providing no undesirable side effects. Cd also causes lipid oxidation that leads to undesired food quality. Garlic (Allium sativum L.) has been used as conventional food...

Antioxidant capacities and polyphenolic contents of two mango cultivars from northern Chile, one of them endemic of an oasis in the Atacama Desert, were compared for the first time. Twenty one phenolic compounds were detected in peel and pulp of mango fruits varieties Pica and Tommy Atkins by HPLC-PDA-MS and tentatively characterized. Eighteen compounds were present in Pica pulp (ppu), 13 in Pi...

This study evaluated the effect of derriobtusone A, a flavonoid isolated from Lonchocarpus obtusus, on two important pathogenic bacteria, Staphylococcus aureus and Escherichia coli, as well as its antioxidant activity and toxicity. Planktonic growth assays were performed, and the inhibition of biofilm formation was evaluated. In addition, antioxidant activity was assessed by DPPH radical scaven...

Purpose: To evaluate the anti-neuroinflammatory effects of Houttuynia cordata extract (H. cordata) in lipopolysaccharide (LPS)-stimulated BV-2 microglial cells, and its anti-oxidant properties. Methods: Anti-oxidant properties were evaluated by 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging assay. Cell viability was assessed by 3-(4, 5-dimethylthiazol-2-yl)-2, 5diphenyl-tetrazolium b...

Composition, antioxidant capacities and cell inhibition properties of curcuminfree turmeric (Curcuma longa L.) oils from different sources were evaluated by chromatographic method, two different in vitro antioxidative activity assays (DPPH* free radical scavenging assay and reducing power assay) and two different cancer cell lines (Caco-2 and MCF-7). Turmeric oil A (TOA) contains zingiberene, t...

Herbal water is referred to the liquid obtained from the distillation of medicinal plants. Different parts of plants, such as flowers, fruits, leaves, seeds and roots have long been used to produce herbal waters. Herbal waters are used as dietary supplements and alternative medicine and are commonly used for flavoring in baking. Previous studies focused on the non-volatile constituents of herbs...

Brewing water plays a crucial role in flavor and potential healthy functions of tea infusion. In this study, seven samples with different physicochemical properties were selected to brew green tea. Results showed that the brewing higher minerals level pH value would reduce yield catechins infusion, which turn caused decrease antioxidant activity large extent. Besides, it was found EGCG, as majo...

The ethanolic extract of Pleurotus florida was studied for its free radical scavenging property on different in vitro models like 1,1 -diphenyl-picryl hydrazyl (DPPH)Assay, Ferric Reducing Antioxidant Power (FRAP) assay and in vitro antilipidperoxidative assay using goat liver homogenate and RBC Ghost model. The in vitro Lipid peroxidation (LPO) was inhibited to a good extent by the Pleurotus f...

Mushrooms collected from Deogyu mountain, Korea, in 2011, were identified as four classes, four orders, 13 families, 22 genera, and 33 species. In particular, agaricales was most abundant and comprised more than 70%. Their antioxidant activities were estimated using three different bioassay methods, the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) radical scavenging assay, 1,1-diph...
