采用毛细管气相色谱法,对产卵前后大鳍鳠肌肉中的脂肪酸组成进行了测定.结果表明,大鳍鳠肌肉中脂肪酸种类丰富,含有22种脂肪酸,油酸(C18:1n-9) 所占比例最高,其次为软脂酸(C16:0) 、棕榈酸(C16:1n-7) 、亚油酸(C18:2n-6) ,所占比例分别为22.38%～37.57%、18.86%～23.95%、 7.00%～11.52%、7.46%～9.97%.EPA和DHA在大鳍鳠肌肉中占有较高的比例,EPA占总脂肪酸的 5.39%,DHA占5.44%.在野生大鳍鳠产卵前后的22种脂肪酸中有8种饱和脂肪酸(SFA) ,6种单不饱和脂肪酸(MUFA) 和8种多饱和脂肪酸(PUFA) ,大鳍鳠肌肉中脂肪酸在产卵前后表现出差异.

Fatty acid composition was analyzed in the muscle of largefin longbarbel catfish Mystus macropterus by gas capillary chromatography. The results showed that there were 22 fatty acids in the muscles,the predominant fatty acids,in terms of relative proportion,being C18:1n-9(22.38%～37.57%) ,followed by C16:0(18.86%～23.95%) ,C16:1n-7(7.00%～11.52%) ,and C18:2n-6(7.46%～9.97%) . The proportion of EPA and DHA were relatively high,accounting for 3.74% and 5.22%,respectively. Eight saturated fatty acids (SFA) ,6 monounsaturated fatty acid(MUFA) and 8 polyunsaturated fatty acids (PUFA) were found in the muscles. Fatty acid composition showed difference in the muscle in the pre-spawning and post-spawning.
