摘要
该文比较8种天竺鲷科鱼的脂肪酸含量,并对各脂肪酸组成进行聚类分析,为天竺鲷科鱼的营养评价提供参考依据。在秋冬季收集来源于湛江海域的单色天竺鲷、箭天竺鲷、四线天竺鲷、拟双线天竺鲷、中线鹦天竺鲷、环尾鹦天竺鲷、褐斑带天竺鲷和垂带天竺鲷,用气相色谱法测定天竺鲷科鱼肌肉中的脂肪酸成分。结果表明,8种天竺鲷科鱼的饱和脂肪酸含量33.22%~42.07%,单不饱和脂肪酸含量8.97%~18.93%,多不饱和脂肪酸含量38.66%~50.96%。多不饱和脂肪酸中,ω-3系脂肪酸含量31.03%~38.42%,其中功能性脂肪酸EPA+DHA(EPA:二十碳五烯酸,eicosapentaenioic acid;DHA:二十二碳六烯酸,docosahexaenoic acid)含量26.26%~34.50%。8种天竺鲷均有较高的EPA和DPA(二十二碳戊烯酸,docosapentaenoic acid)含量,其中单色天竺鲷的DPA含量最高,为7.00%。脂肪酸聚类分析表明,天竺鲷科鱼不能科内属间聚类,但可与须鲷科鱼进行科间聚类。
The fatty acid contents of eight species of cardinalfishes were compared,and the fatty acid compositions were analyzed by cluster analysis,which could provide a reference for the nutritional evaluation of cardinalfishes.Eight species of cardinalfishes,including Apogon unicolor,Rhabdamia gracilis,Apogon fasciatus,Apogonichthyoides pseudotaeniatus,Ostorhinchus kiensis,Ostorhinchus aureus,Taeniamia fucata and Apogon cathetogramma were collected from the sea near Zhanjiang in autumn and winter.The fatty acids in their muscles were determined by gas chromatography.The results showed that the nutritive value of fatty acids in eight species of cardinalfishes were higher,with the contents of saturated fatty acids ranging from 33.22%to 42.07%,monounsaturated fatty acids ranging from 8.97%to 18.93%,and polyunsaturated fatty acids ranging from 38.66%to 50.96%.Among the polyunsaturated fatty acids,the content ofω-3 fatty acids ranged from 31.03%to 38.42%,and the content of functional fatty acids EPA+DHA ranged from 26.26%to 34.50%.The contents of EPA and DPA in all eight cardinalfishes was higher,and Apogon unicolor had the highest content of DPA(7.00%).Fatty acid cluster analysis showed that the fish of cardinalfishes could not be clustered among genera within the family,but could be clustered between families such as Mullidae.
