【Abstract】 The nutrient components of Monostrom latissimum, which was cultivated in China, were measured and analyzed in this paper. The result indicated that the content of protein, total amino acid and free amino acid in dried thallus was 23.1, 19.95 and 1.27% respectively. The fat content was 2.64%, in which polyunsaturated fatty acid reached 50.25%. The content of chlorophyll a, chlorophyll b, carotenoids accounted for 250.46, 479.75, and 78.63mg/100g dried wt respectively. Compared with laminaria and porphyra to evaluate in nutriology,the results showed the chemical scores of essential amino acid were ninety one for M. latissimum that can probably be used as good raw material of health food and marine drug.更多还原
