ResumoThe marine red algae, Chondrus crispus and Polysiphonia lanosa, were harvested from the wild and their lipids isolated, characterized and quantified. Double banding of monoglycosyldiacylglycerol, diglycosyldiacylglycerol and sulphoquinovosyldiacylglycerol was observed on TLC, probably caused by the presence of different molecular species. The sulphur analogue of phosphatidylcholine was provisionally identified in both algae. Over 20 fatty acids were observed in each alga, with the main ones being palmitic, oleic, arachidonic and eicosapentaenoic acids. The fatty acid compositions of the acyl lipids were determined. trans-Δ3-Hexadecenoic acid was found exclusively in phosphatidylglycerol. The three glycosylglycerides (monoglycosyl-, diglycosyl- and sulphoquinovosyldiacylglycerol) were major components, with phosphatidylglycerol the main phosphoglyceride in both algae.
