Placenta, as a reservoir of nutrients, has been widely used in medical and cosmetic materials. Here, we focused on the antioxidant properties of placental extract and attempted to isolate and identify the main antioxidant factors. Porcine placental extracts were prepared through homogenization or acid hydrolysis, and their antioxidant activity was investigated in the human keratinocyte HaCaT ce...

Antioxidant micronutrient supplementation may be beneficial for critically ill patients. Often, cocktails of antioxidant micronutrients are used. Consequently, meta-analyses of available randomized controlled trials of antioxidant micronutrient supplementation are of particular interest. Because the majority of randomized controlled trials included in these meta-analyses use a combination of se...

Three variations of tomato fudge were prepared using tomato powder at different proportions with sugar, whole milk and honey and evaluated for sensory quality, antioxidant activity, microbial count and consumer acceptability. It was observed that the fudge prepared by using 1-3 g of tomato powder were having higher sensory scores while antioxidant activity was found highest in fudge having 5 g ...

Citrullinated synovial antigens and the antibodies produced against them play a important role in the path physiology of RA[1]. Anti-CCP antibody positivity seems to be associated with increased synovial fluid oxidant activity (increased MDA and MPO levels) in patients with RA[2]. Excessive free radical production rather than impaired antioxidant enzymes activity due to autoantibody inhibition ...

Five new xanthones, 1,3,6-trihydroxy-5-methoxy-4-prenylxanthone (1), 1,3,5-trihydroxy-6-methoxy-2-prenylxanthone (2), 1,3,5-trihydroxy-4-(3-hydroxy-3-methylbutyl) xanthone (3), 1,3,6-trihydroxy-4-prenylxanthone (4), 3,6-dihydroxy-1,5-dimethoxyxanthone (5) and one new flavonoid, 3,5,7,4'-tetrahydroxy-2'-methoxyflavone (6) along with seven known xanthones and seven known flavonoids were isolated ...

The antioxidant activity of Syzygium cumini leaf extracts was investigated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging and ferric-reducing antioxidant power (FRAP) assays. The methanolic extract and its four water, ethyl acetate, chloroform, and n-hexane fractions were prepared and subjected to antioxidant evaluation. The results showed that the ethyl acetate fraction...

Antioxidant activity of Avicenni marina L and Avicennia officinalis L fruit extracts in ethyl acetate, acetone, methanol and ethanol were studied by ABTS, CrO5 and FRAP method. All the extracts possessed significant amount of the antioxidant activity, extracts in methanol and ethanol was demonstrated convincingly higher antioxidant activity by all the three methods. Whereas, the ethyl acetate e...

background: acrylamide (acr) is a well-known industrial toxic chemical that produces neurotoxicity, which is characterized by progressive central and peripheral neuronal degeneration. chrysin is a natural, biologically active flavonoid compound, which is commonly found in many plants. the antioxidant and neuroprotective properties of chrysin have been demonstrated. methods: in this study, the p...
