摘　　要：目的分析7种隆头鱼科鱼肌肉脂肪酸组成。方法用毛细管气相色谱法测定邵氏猪齿鱼、黑带海猪鱼、断纹紫胸鱼、三带颈鳍鱼、洛神颈鳍鱼、九棘长鳍鹦鲷、红颈拟隆头鱼肌肉中脂肪酸组成。结果 7种隆头鱼肌肉含有24种脂肪酸,其中饱和脂肪酸、单不饱和脂肪酸、多不饱和脂肪酸(PUFA)分别占32.43%~41.20%、13.45%~21.85%、33.71%~52.61%;在PUFA中,ω-6系、ω-3系脂肪酸、DHA+EPA分别为8.47%~16.55%和24.67%~37.08%、19.80%~35.06%。脂肪酸组分聚类分析表明,7种隆头科鱼可分成3群组,其中黑带海猪鱼与三带颈鳍鱼的脂肪酸成分含量相近,断纹紫胸鱼与九棘长鳍鹦鲷脂肪酸成分含量相近。结论 7种隆头鱼科鱼肌肉中含有丰富的不饱和脂肪酸,其中黑带海猪鱼、断纹紫胸鱼和三带颈鳍鱼肌肉中EPA+DHA含量高达30%以上,具有较高的食用价值及开发利用价值。Objective To analyze the muscular fatty acids of 7 species of Labridae. Methods Muscular fatty acids of Choerodon schoenleinii, Halichoeres nigrescens, Stethojulis terina, Iniistius trivittatus, Iniistius dea, Pteragogus enneacanthus, and Pseudolabrus eoethinus was determined by capillary gas chromatography. Results Twenty-four fatty acids were determined in 7 species of Labridae, of which saturated, monounsaturated and polyunsaturated fatty acids accounted for 32.43%-41.20%, 13.45%-21.85%, and 33.71%-52.61%, respectively. Of polyunsaturated fatty acids, ω-6 and ω-3 fatty acids, and DHA+EPA were 8.47%-16.55%, 24.67%-37.08%, and 19.80%-35.06%, respectively. Cluster analysis showed that 7 wreckfishes were divided into 3 groups. Fatty acid components were comparable between Halichoeres nigrescens and Iniistius trivittatus and between Stethojulis terina and Pteragogus enneacanthus. Conclusion The unsaturated fatty acids are abundant in the muscle of 7 wreckfishes. Halichoeres nigrescens, Stethojulis terina and Iniistius trivittatus possess a high nutritional and developmental value because their muscular EPA+DHA contents are more than 30%.
