Phenolic compounds and antioxidant activity of Brazil nut
Soluble phenolics in brown skin was 1236.07 as compared to 406.83 in kernel and 519.11 mg/100 g in whole nut. Bound phenolics content of brown skin was also 86- and 19-folds higher than kernel and whole nut, respectively. Similarly extracts from the brown skin exhibited the highest antioxidant activity.

Polyphenols from Root, Tubercles and Grains Cropped
The authors reported that the high antioxidant capacity of the beetroot juice shot was attributed to its polyphenol contents. The antioxidant capacity of 4880 ± 68.6 mg of GAE L −1 polyphenol content was reduced to 3188.6 ± 77.14 mg GAE L −1 following the gastric phase digestion, but still at 2/3 of the initial antioxidant level.

Stabilization of Inorganic CsPb0.5Sn0.5I2Br Perovskite
Herein, an effective method for stabilizing CsPb 0.5 Sn 0.5 I 2 Br is proposed to realize high‐efficiency PSCs via antioxidant tea polyphenol (TP). It is found that TP can not only slow down the oxidation of Sn 2+ but also regulate perovskite film crystallization during the formation of perovskite films via coordination interaction, leading ...

Nanoencapsulation of carotenoids: a focus on different
Carotenoids are isoprenoid compounds with polyene chains that may contain up to 15 conjugated double bonds. This chemical characteristic confers to these compounds instability to light, oxygen and heat and functionality such as provitamin A characteristic, antioxidant activity and anticancer activities (Lerfall 2016). Therefore, carotenoids are ...

Phenolic compounds and antioxidant activity of Brazil nut
Studies by Blomhoff et al. (2006) on the antioxidant activity of 11 different nuts with and without pellicle (skin) clearly showed that nuts with pellicle had higher antioxidant capacity in terms of TEAC and ferric reducing antioxidant power (FRAP). The higher antioxidant activity of the pellicle can be associated with a higher content of phenolics, and this agrees with the present results where the brown skin of Brazil nut contained higher amounts of bound phenolics than the kernel or whole

Antioxidant activity of five Brazilian plants used as
RESULTS AND DISCUSSION. The results indicate that the ethanol extract of all the plants demonstrated antioxidant activity, but the extract of M. charantia showed the highest activity among the species studied with a CE 50 value (the concentration necessary to obtain half of the maximum scavenging activity) of 9.64 ± 0.045 μg/mL.
