Abstract EN
Antioxidant activity and mineral composition were evaluated seasonally from spring to autumn 2010 in the three common seaweeds Ulva lactuca Linnaeus (Chlorophyta), Jania rubens (Linnaeus) J.V.
Lamouroux and Pterocladia capillacea (S.G.
Gmelin) Bornet (Rhodophyta).
The antioxidant activity was measured with b-carotene, total phenol content and DPPH (2,2-diphenyl- 1-picrylhydrazyl).
Seaweeds were collected from the rocky site near Boughaz El-Maadya Abu-Qir Bay of Alexandria, Egypt.
The results showed maximum increase of b-carotene in P.
capillacea during summer.
A significant increase in total phenolic content at P 6 0.05 was found in the red alga (J.
rubens) during summer.
Also, U.
lactuca showed the maximum antioxidant scavenging activity especially during summer.
Minerals in all investigated samples were higher than those in conventional edible vegetables.
Na/K ratio ranged between 0.78 and 2.4 mg/100 g, which is a favorable value.
All trace metals exceeded the recommended doses by Reference Nutrient Intake (RNI).
During summer season, it was found that Cu =2.02 ± 0.13 and Cr= 0.46 ± 0.14 mg/100 g in U.
lactuca and Fe had a suitable concentration (18.37± 0.5 mg/100 g) in P.
capillacea.
The studied species were rich in carotenoids, phenolic compounds, DPPH free radicals and minerals, therefore, they can be used as potential source of health food in human diets and may be of use to food industry.
