Abstract: Objective: To analyze the nutrient constituents in Ophiura kinbergi and provide a theoretical basis for its development and utilization. Methods: The national standards of china were used to determine water content, ash, crude fat, protein, amino acid; phenol-sulfuric acid method, atomic absorption spectroscopy method and gas chromatography-mass chromatography were used to determine the contents of total sugar, inorganic elements and fatty acids, respectively. Results: The contents of water, ash, protein, total sugar, rude fat and amino acid in Ophiura kinbergi were 1.32%, 23.09%, 9.65%, 5.16%, 2.64% and 9.30%, respectively. The contents of unsaturated fatty acid and saturated fatty acids were 61.33% and 38.67%. Ophiura kinbergi was also rich in other nutrient elements. Conclusion: Ophiura kinbergi has a good development and utilization value due to its rich nutrients.

Key words: Ophiura kinbergi, nutrient composition, content determination
