采用毛细管气相色谱法对采自渤海的22种海洋植物的脂肪酸组成进行了分析,这些植物分属于Ceramiales、Cryptonemiales、Nemalionales、Laminariales、Chordariales、Scytosiphonales、Desmarestiales、Dictyosiphonales、Fucales、Dictyotales和Ulvales。渤海藻中多不饱和脂肪酸(FA)含量低于黄海同类藻。红藻具有相对高水平的酸16:0、18:1(n-7)、18:1(n-9)、20:5(n-3)和20:4(n-6),并且所检查的那些富含C-20 PUFA,这些PUFA主要是花生四烯酸和二十碳五烯酸。在褐藻门中发现的主要脂肪酸是14:0、16:0、18:1(n-9)、18:2(n-6)、18:3(n-3)、18:4(n-3)、20:4(n-6)和20:5(n-3)。C18多不饱和脂肪酸是更大的丰度在褐藻比在红藻检查。三种绿色藻的脂肪酸组成模式相似,主要成分为16:0、16:4(n-3)、18:1(n-7)、18:2(n-6)、18:3(n-3)和18:4(n-3)。它们含有16:3(n-3)和更多16:4(n-3),富含C18 PUFA,主要是18:3(n-3)和18:4(n-3),并且18:1(n-7)/18:1(n-9)比率高于1。(C)2002爱思唯尔科技有限公司。保留所有权利。
The fatty acid compositions of 22 species of marine macrophytes, belonging to the Ceramiales, Cryptonemiales, Nemalionales, Laminariales, Chordariales, Scytosiphonales, Desmarestiales, Dictyosiphonales, Fucales, Dictyotales and Ulvales and collected from the Bohai Sea, were determined by capillary gas chromatography. The contents of polyunsaturated fatty acids (FAs) in the Bohai Sea algae, in comparison with the same species from the Yellow Sea were found to be lower. Red algae had relatively high levels of the acids 16:0, 18:1(n-7), 18:1(n-9), 20:5(n-3) and 20:4(n-6), and those examined were rich in C-20 PUFAs, these chiefly being arachidonic and eicosapentaenoic acids. The major FAs encountered in the Phaeophyta were 14:0, 16:0, 18:1(n-9), 18:2(n-6), 18:3(n-3), 18:4(n-3), 20:4(n-6) and 20:5(n-3). C18PUFAs are of greater abundance in the brown algae than in the red algae examined. All three green algae from the Ulvales had similar fatty acid patterns with major components, 16:0, 16:4(n-3), 18:1(n-7), 18:2(n-6), 18:3(n-3), and 18:4(n-3). They contained 16:3(n-3) and more 16:4(n-3), were rich in C18PUFAs, chiefly 18:3(n-3) and 18:4(n-3) and had 18:1(n-7)/18:1 (n-9) ratios higher than 1. (C) 2002 Elsevier Science Ltd.
