“…The ferric ion reducing antioxidant power (FRAP) assay was done according to Todorovic et al (2015), results were expressed as mean ± standard error and units in μmol Trolox Equivalents (TE)/100 g (fw). The total reducing power assay (TRPA) was determined according to a previously described procedure (Dliveira et al, 2011), results were expressed as mean ± standard error and units in Trolox Equivalents (TE) / 100 g (fw).…”

Rosa Laevigata Michx., contents of bioactive components contribute to the health beneftis of consuming fresh, snacks and medicine, is widely used as the Chinese medicinal herbs. The effect of fruit ripening on the bioactive compounds and antioxidant capacity of Rosa laevigata Michx fruits was investigated. The results showed that, the bioactive compounds, including titratable acidity, reducing sugar, total ascorbic acid, total polyphenol and total flavonoids, significant changes occurred at different ripening stages. The contents of reducing sugar, total polyphenol and total flavonoids were directly proportional to the maturity. However, the content of titration acid and ascorbic acid is inversely proportional to the maturity. Antioxidant capacity and RDS inhibition are proportional to the maturity, and the antioxidant capacity of Rosa laevigata Michx significantly increase during maturity. The Rosa laevigata Michx fruits at fully ripe stage had higher healthcare and medicinal value.Keywords: Rosa laevigata Michx.; ripening stages; bioactive compounds; antioxidant capacity.Practical Application: Dptimizing harvesting and postharvest management of Rosa laevigata Michx.

“…Mandarin orange juices (Miglio et al, 2014) and cookies containing chocolate chips possessed the highest antioxidant capacity (Sun et al, 2008). Cocoa processing products (Todorovic et al, 2015), and jam and marmalade (Kamiloglu et al, 2015) increase dietary antioxidants. Biscuits, which include protein, crude fiber, iron, and calcium, increased antioxidant properties (Ajibola et al, 2015).…”

Individuals with autism spectrum disorders (ASD) have impaired detoxification capacity. Investigating　the neurobiological bases of　impaired antioxidant capacity is thus a research priority in the pathophysiology of ASD.　We measured　the urinary levels of hexanoyl-lysine (HEL) which is a new oxidative stress　biomarker, total antioxidant power (TAP) and DNA methylation biomarker 8-hydroxy-2'-deoxyguanosine (8-OHdG), and the plasma levels of superoxide dismutase (SOD), which is a major antioxidant enzyme. We examined whether the urinary levels of these enzymes and biomarkers may be related to symptoms of social impairment in 20 individuals with ASD (meanage,11.1±5.2years) and 12 age- and gender-matched healthy controls (meanage,14.3±6.2years). Symptoms of social impairment were　assessed using the Social Responsiveness Scale (SRS). The dietary TAP of the fruit juice, chocolate, cookies, biscuits, jam and marmalade were significantly higher in the ASD group than in the control group, although the intake of nutrients was not significantly different between the groups. The urinary TAP levels were significantly lower in the ASD group than in the control group. There were no significantly differences in urinary HEL and 8-OHdG levels between the ASD and control groups. The SRS scores were significantly higher in the ASD group than in the control group. Stepwise regression analysis revealed that urinary TAP levels and plasma SOD levels can differences in the biomarkers and the SRS scores between the ASD group and the control group. The endogenous antioxidant capacity may be deficient without altered urinary HEL and 8-OHdG levels in individuals with ASD. The plasma SOD levels may be related to reduced endogenous antioxidant capacity.
