| 摘 要： | 海胆性腺中脂肪酸含量丰富,β-胡萝卜素含量高,是一种营养价值较高的食物来源,不同种、不同群体间、不同性别海胆性腺中二者的组成与含量存在差异。对我国北方海区4种经济海胆(虾夷马粪海胆、光棘球海胆、马粪海胆和海刺猬)以及大连黑石礁、旅顺、獐子岛3个群体的光棘球海胆性腺中的脂肪酸组成及β-胡萝卜素含量进行了测量和分析。结果显示:不同种海胆、同种海胆的不同群体及不同性别海胆性腺中脂肪酸、β-胡萝卜组成与含量均存在差异。不同种海胆间,光棘球海胆性腺中脂肪酸种类最多为31种,虾夷马粪海胆性腺中种类最少为24种；不同群体的光棘球海胆间,黑石礁群体性腺中脂肪酸种类最多为29种,旅顺群体最少为26种。雄性、雌性马粪海胆性腺中β-胡萝卜素含量均显著高于其他3种雌性海胆(P<0.01)。3个群体的光棘球海胆性腺中,黑石礁群体雄性性腺β-胡萝卜素含量显著低于其他2个群体(P<0.05)；獐子岛群体雌性性腺中β-胡萝卜素高于其他2个群体,差异极显著(P<0.01)。上述结果为进一步开展海胆杂交及海胆优良品种的选育奠定了基础。

| Abstract: | Urchin gonad is a kind of nutritional and healthy food with abundant fatty acid and β-carotene, and their contents are different in different species and populations. We explored the fatty acid composition and β-carotene content of sea urchin gonad in 4 different species (S.intermedius, S.nudus, H.pulcherrimus, G.renularis) collected from Dalian and 3 populations of S.nudus collected from Heishijiao, Lüshun and Zhangzidao. The results showed that the fatty acid composition and β-carotene content of sea urchin gonad were different among the 4 species. The kinds of fatty acids in S.nudus were the largest with 31, while that of S.intermedius were the smallest with 24. Among the 3 populations of S.nudus, the kinds of fatty acids in Heishijiao were the largest with 29, while that of Lüshun were the smallest with 26. The β-carotene content of male and female urchin gonad in H.pulcherrimus were both significantly higher than the others (P<0.01). Among the 3 populations of S.nudus, the β-carotene content of male urchin gonad in Heishijiao population was lower than the others (P<0.05); while that of female gonad in Zhangzidao population was significantly higher than the others (P<0.01). The above results set up a foundation for further hybridization and breed selection of sea urchin. |
