摘要：

Total fatty acids from Heterosigma akashiwo contained 4.8-8.9 wt% of octadecapentaenoic acid (18:5n-3) through the growth cycle. This polyunsaturated fatty acid was preferentially located in monogalactosyldiacylglycerols and digalactosyldiacylglycerols (20.1% and 10.2% of fatty acids, respectively, at day 18) with 0.3% or less in sulphoquinovosylglycerol (SQDG) +phosphatidylglycerol (PG) and phosphatidylcholine. The SQDG+PG fraction contained six cis 16:1 isomers. These findings are discussed in relation to algal taxonomy. (C) 1997 Elsevier Science Ltd.
