实验测定和比较了性腺发育至V期的雌性成体纹缟虾虎鱼的肌肉、肝脏和卵巢组织中水分、总脂含量及其脂肪酸组成。结果表明:(1)肌肉、肝脏和卵巢中的水分含量依次降低,且差异显著(P〈O.05)。肌肉、肝脏和卵巢中的总脂含量分别为1.32%±0.08%、7.75%±0.38%和26.73%±0.59%。3种组织间的总脂含量具有显著性差异(P〈0.05),其中卵巢中总脂含量最高,其次为肝脏中的含量,肌肉中含量最低。(2)肌肉中饱和脂肪酸(SFA)总量明显高于肝脏和卵巢,3种组织中SFA含量呈显著性差异(P〈O.05);肝脏中单不饱和脂肪酸(MUFA)C16:1含量最高,肌肉、肝脏和卵巢中的含量分别为11.90%±0.71%、15.28%±2.42%和9.49%±0.37%,3种组织间含量呈显著性差异(P<0.05);多不饱和脂肪酸(PUFA)、ω3PUFA和ω6PUFA在卵巢中的含量显著高于肌肉和肝脏中含量(P〈0.05),而肌肉和肝脏间的差异不显著(胗0.05)。肌肉、肝脏和卵巢中二十碳五烯酸(EPA)、二十二碳六烯酸(DHA)的总量依次升高,在3种组织间的含量分别为30.17%±1.02%、30.53%±0.50%和34.33%±0.71%,卵巢中的含量显著高于肌肉和肝脏中的含量(P〈0.05),而后两者间的差异不显著(P〉0.05)。3种组织中DHA/EPA的比值分别为1.50、1.75和1.59,c03PUFA/Ec06PUFA的比值分别为6.44、8.05和7.00。DHA/EPA和c03PUFA/Ec06PUFA均在肝脏中最高,其次为卵巢,肌肉中最低。
Research was made in this paper on the moisture, lipid content and fatty acid composition of muscle, liver and ovary of adult female Tridentiger trigonocephalus collected from the Yangtze Estuary at V stage of ovary development. The results indicated that: (1) The moisture content in muscle, liver and ovary was reduced successively, and the value was significantly different among these three tissues (P〈0.05). The total lipid content in these three tissues was (1.32%~0.08%), (7.75%~0.38%), and (26.73%~0.59%), respectively. There was significant difference in total lipid content among these three tissues, and the highest was in ovary, followed by liver, and the lowest was in muscle. (2) The content of SFA in muscle was significant higher than that in liver and ovary. There was significant difference in SFA content among three tissues (P〈0.05). About the MUFA, C16:1 content of liver is the highest. The C16:1 content in muscle, liver and ovary were (11.90%±0.71%), (15.28%±2.42%) and (9.49%±0.37%) respec- tively, and there was significant difference among these three tissues (P〈0.05). The content of PUFA, co3PUFA, O36PUFA in ovary was significantly higher than that in muscle and liver (P〈0.05), but showed no significant difference between muscle and liver (P〉0.05). The total content of EPA and DHA in muscle, liver and ovary were increased successively. The total content of EPA and DHA in these three tissues was (30.17%±1.02%), (30.53%±0.50%) and (34.33%±0.71%), respectively. The content of EPA and DHA in ovary was significantly higher than that in muscle and liver (P〈0.05), but showed no significant difference between muscle and liver (P〉0.05). The ratio of EPA to DHA (EPA/DHA) in these three tissues was 1.50, 1.75 and 1.59 respectively, and the ratio of total o33 polyunsaturated fatty acids to total o36 polyunsaturated fatty acids (∑ω3PUFA/∑ω36PUFA) in these three tissues was 6.44, 8.05 and 7.00, respective
