摘要
采用气相色谱仪测定了小荚蛏不同生理阶段(配子发生期、成熟期和排放期)软体部脂肪酸的组成.结果表明,小荚蛏软体部含有23种脂肪酸,其中饱和脂肪酸(SFA)5种,单不饱和脂肪酸(MUFA)5种,多不饱和脂肪酸(PUFA)13种.各生理阶段的SFA、MUFA和PUFA含量差异极显著,23种脂肪酸除C20:3含量无显著差异外,其余22种脂肪酸含量差异均显著;SFA含量以排放期为最高,配子发生期为最低;MUFA含量在配子发生期高于成熟期和排放期,PUFA含量在配子发生期和成熟期高于排放期.
Composition of the fatty acids in the edible part of Siliqua minima at different physiological stages was examined by means of gas chromatography. The results indicated that there were 23 kinds of fatty acids including 5 kinds of saturated fatty acids （SFA）, 5 kinds of monounsaturated fatty acids （MUFA） and 13 kinds of polyunsaturated fatty acids （PUFA）. According to analysis, the differences of concentrations of SFA MUFA and PUFA in different physiological stages were obvious. Except C20：3, the differences of concentrations of all the other 22 fatty acids were obvious. Maximum concentration of SFA occurred during the spawning phase, but minimum concentration occurred during the gametogenesis phase. The concentration of MUFA in gametogenesis phase was higher than that in maturation and spawning phase. The concentrations of PUFA in gametogenesis and maturation phase were higher than that in spawning phase
