The impact of altitude on the different sugars and acids feijoa fruit is unknown. For that reason, objective this study was to evaluate altitudinal effect content organic (citric malic) (glucose, fructose, sucrose) during development fruits. took place in towns Tenjo (2,580 m asl with 12.3°C, 76.4% RH, 190mm precipitation) San Francisco de Sales (1,800 asl, 18.5°C; 86.1% 573 mm precipitation), ...

Long exposure of UV radiation increases risk of skin diseases such as cancer and photoallergic reactions. UV-B (280-320 nm) radiation is mainly responsible for inducing the skin problems. Skin protection is a suitable method against ultraviolet radiation-induced damage. Various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they have limit...

Antioxidant activity of Feijoa sellowiana leaves and fruit peels was investigated employing various in vitro assay systems. IC50 for DPPH radical-scavenging activity was in the order: leaf aqueous extract, LW (7.25 ± 0.31) > leaf methanolic extract, LM (12.5 ± 0.34) > fruit peels aqueous extract, FW (20.25 ± 0.52) > fruit peels methanolic extract, FM (34.5.29 ± 0.44) μg ml, respectively. The ex...

Feijoa (Acca sellowiana) is a native Brazilian fruit with peculiar flavour, considerable amount of bioactive compounds and antioxidant activity. Even though this tree currently cultivated in several countries around the world, Brazil, process domestication underway, selection breeding new genotypes that are more productive better quality necessary. The objective work was to evaluate phenotypic ...
