The exposure to ultraviolet (UV) radiation cause oxidative stress translated by the appearance of ROS (Reactive Oxygen Species), which contributes to disease occurrence. The chemical natural compounds, such as polyphenols, present an antioxidant activity and may be used in the inhibition of the oxidative stress generated by ROS. Also, they may be used as UV shield. The flowers soft extract of Elaeagnus angustifolia L. contents polyphenol compounds such as flavonoids and phenolcarboxylic acids and it has an antioxi...

This work has revealed dates about cytotoxic potential of benzoic acid (E210), citric acid (E330) and sodium phosphate (E339) currently used as pharmaceutical or food additive. The testing was made in experimental conditions with nauplius larvae of Artemia sp., brine shrimp biotester method. The Artemia salina bioassay was chosen because it is versatile, viable, fast and low cost screening assay. Furthermore, there is a good correlation between the in vivo and the in vitro tests, and this method is a useful tool f...
