Some nutritional components of the edible seaweeds Cryptonemia obovata and Rhodymenia corallina were determined. The amino acid content ranged from 1.0 ± 0.3 to 4174.2 ± 14.2 mg 100g−1 dry wt in C. obovata and between 0.9 ± 0.3 and 2657.0 ± 13.5 mg 100g−1 dry wt in R. corallina. The most abundant fatty acid in C. obovata was palmitic acid, reaching a value of 36.5 ± 0.2%, while in Rhodymenia corallina the main fatty acid was oleic acid, reaching a value of 24.7 ± 0.07%. Both seaweeds showed an important content of EPA (C20:5ω3). In C. obovata,α-tocopherol was the principal tocol (138.5 ± 4.9 mg kg−1 lipid), while in R. corallina, it was γ-tocotrienol (850.3 ± 9.4 mg kg−1 lipid). Furthermore, β-carotene was the main carotenoid pigment found in C. obovata.
