Fucoxanthin Content and Chemical Composition in Brown Seaweed, Nizamuddinia zanardinii (Phaeophyta) Collected from Mirbat, Southern Oman (The Arabian Sea)
ABSTRAKT
Marine seaweeds are vast and unused fishery resources in Oman. A preliminary study was conducted to estimate the concentration of pigment fucoxanthin and other useful chemical substances in kelp, Nizamuddinia zanardinii (Schiff.) P. Silva, which dominates the southern coast of Oman in the Arabian Sea. The density of N. zanardinii varied between 7.0 and 7.9 kg · m-2, and dry weight was 1.03–1.46 kg · m-2 (approximately 15.9% of wet weight). The concentration of fucoxanthin was estimated at 15.5–17.3 mg/100 g wet weight. The percentage yield of sodium alginate was 13–27%. The species is rich in carbohydrates (> 60% dry weight) and protein (15.5%), but it contains lower levels of ash, fat, and calories. N. zanardinii has high concentrations of potassium, magnesium, sodium, calcium and iodine. Brown seaweed N. zanardinii is one of the major potential fishery resources in Oman and can be used to develop a new seaweed industry as well as many different commercial products.
