本文对刺参不同部位（体壁、肠和卵）中的主要营养成分进行了研究。结果表明：刺参属于高蛋白质食品，且肠和卵的蛋白质含量高于体壁；富含人体所必需的铜、铁、锰、锌等元素，这些元素更易在肠中富集；δ-维生素E在刺参中含量丰富，以肠中最高；体壁中酸性粘多糖含量较高，为5.03%；氨基酸组成全面，鲜味氨基酸的含量丰富，体壁中羟脯氨酸含量很高，为4.20%，是动物胶原蛋白的主要成分；鉴定出23种脂肪酸，必需脂肪酸含量高，尤其C20∶5 n3（EPA）在肠中高达16.06%。因此，刺参具有较高的营养价值和一定的药用价值。

Nutritive and functional composition in different parts (body wall, intestine and spawn) of Stichopus japonicus were investigated in this paper. The results were shown as follows: Stichopus japonicus was of high protein and the content of protein in the intestine and spawn were higher than those in body wall; Cu, Fe, Mn, Zn and other metal elements were abundant, which were more likely enrichment in the intestine; the content of δ-VE was high, especially in the intestine; the percentage content of acid mucopolysaccharide in the body wall was high and the content was 5.03%; composition of amino acids was complete, and free amino acids (FAA) were rich. Hydroxyproline which was the basis of collagen protein accounted for 4.20% in the body wall; there were 23 kinds of fatty acids were detected and it was found that the essential fatty acids content was high, especially the content of C20∶5 n3 (EPA) was 16.06% in the intestine. In conclusion, Stichopus japonicus was of high nutrition value and some officinal value.
