Antioxidant activity compared

Oleosomes of seabuckthom fruit flesh were isolated by physical separation techniques and their higher stabilities and antioxidant activities compared to solvent-extracted oil were demonstrated. ... 

Carrots (Daucus carota) are excellent sources of (3-carotene and vitamin A, although they have been reported to exert low antioxidant activity compared to some other vegetables (Al-Saikhan and others 1995 Cao and others 1996 Ramarathnam and others 1997 Vinson and others 1998 Beom and others 1998). However, boiling carrots for 30 min significantly improved their antioxidant activity toward coupled oxidation of (3-carotene and linolenic acid (Gazzani and others 1998). 

A detector records a signal at 515 or 517 nm [64, 65]. Depending on the antioxidant activity of the separated substances, greater or smaller signal fading can be observed, resulting in a negative peak. The surface area of the peak, proportional to the antioxidant activity (compared... 

Gneafricanins A, C-E and F (560, 562-565), longusol A (577) and bisisorhapontigenin B (518) all exhibited a considerable degree of activity in lipid peroxide inhibition and superoxide dismutases (SOD) like antioxidant activity [211]. Bisisorhapontigenins E-G and 13b-methoxy bisisorhapontigenin G (523-526) all possessed potent antioxidant activity compared with vitamin E [253]. 

Green tea Microfine particles (300-1000 nm) were produced which had enhanced antioxidant activity compared to middle grade tea (>1000 nm) Shibata (2002)... 

Siriwardhana and Shahidi [33] evaluated the Trolox equivalents antioxidant capacity (TEAC) of almond and its by-product extracts and found that ethanolic extracts, at the same concentration the TEAC values, followed the order of brown skin > green shell cover > whole seed (kernel). Values of brown skin and green shell cover extracts were 12.6- and 9.8-fold higher than that of whole seed extract, respectively. Alasalvar et al. [30] observed that hazelnut kernel and its green leafy cover extracts from 80% (v/v) ethanol were characterized as having significantly lower (P < 0.05) total antioxidant activity compared to those of extracts obtained from 80% (v/v) acetone.

Anti-inflammatory / antioxidant activity. Seed extracts have antioxidant activity comparable to that of BHT, while the triterpene acid esters have radical scavenging, COX, and neutrophil elastase inhibitory activity in vitro EPO administration reduced tissue oxidative stress in hyperlipemic rabbits. ... 

Among cereals, sorghum and maize had higher antioxidant activity compared to wheat, oats, and rice. Sorghum is known to contain the highest content of phenolic compounds, reaching up to 6% in some varieties (Dicko et al. 2006). The wide array...
