Abstract

Antioxidant and antibacterial potential of hydro-alcoholic extracts of 3 marine
green, brown and red algae species were investigated.According to the Trolex
antioxidant potential test, Entreromorpha intestinalis (green algae) and
Gracilaria corticata (red algae) showed the highest and the lowest amounts of
total phenol and the best antioxidant activity, respectively. In this test, the most
inhibitory percent were calculated in green algae and the lowest percent were
from Cystoseiramyrica (brown algae). According to the Azinobis ethyl
thiazolinesolphonic test (ABTS, 50mg/ml), green algae and brown algae
showed the highest and the lowest amounts of total phenol and the best
antioxidant activity, respectively. Hydro-alcoholic extracts from these different
species had no antibacterial effect on two species of bacteria, which were tested
in this study.
