Abstract
The main objective of this work is to characterize the seasonal influences on the potential nutritional assessment of extracts of the brown alga Cystoseira amentacea var. stricta, harvested on the khadra coast, in the wilaya of Mostaganem (Algeria). The Stricta cystosira extracts have been shown to have high seasonal physicochemical parameters in which the biochemical parameters determine that the maximum total chlorophyll content was 21.38 μg / ml, with a maximum value of 8.45 ± 1.06 μg / ml. Carotenoids and. the humidity give a 52% Spring with 22.6% of ash in the Autumn, with a 15.5% wilting and 21 ± 1.16% carbohydrate and 130 (AAE / 100g) of ascorbic acids in the Summer, the lipids it exceeds 19.8%. a 120 G AE / 100g total phenolic content record in the winter with a better anti-free radical activity it exceeds 0.71 (EAA / mg) in the Autumn and 50% inhibition of the percentage of CI to give a 6.31 μg / ml at the L The results indicated a change in biochemical compositions were abundant according to the seasons. These results have proved to be an important contribution to the valorization of these species of macroalgae and isolation some bioactive molecules in the different pharmaceutical field as a source of recent biochemical compounds and selected as important nutritional products.
