摘要：

The fatty acid compositions of Gracilaria verrucosa, G. bursa-pastoris, G. debilis and Gracilaria sp. were determined. Arachidonic and eicosapentaenoic acids predominated among the fatty acids. The arachidonic: eicosapentaenoic acid ratio in algae of the genus Gracilaria fell into three categories. The fatty acid content in G. verrucosa was not influenced significantly by environmental factors. An error in the identification of several morphologically similar Gracilaria species as G. verrucosa may be responsible for the discrepancy in the literature data about the arachidonic and eicosapentaenoic acid contents in this species. Possible pathways of eicosapentaenoic acid biosynthesis from arachidonic or from alpha-linolenic acids in red algae are discussed.
