Phospholipid fatty acid composition was studied in two Senegalese sponges of the family Suberitidae. More than fifty acids were identified in either Pseudosuberites sp. or Suberites mssa. A series of 2-hydroxy long-chain fatty acids (C22to C2,)a ccounted for almost 50% of the total acid mixture of Pseudosrtberittv sp., including 2-hydroxyhexacosanoic acid (26%) and the unusual 2-hydroxy-heptacosanoic acid not yet reported in any sponge. A series of 3-hydroxy shon-chain fatty acids was also detected in this sponge. Two new fatty acids were identified in these sponges, namely 4,8-dimethyldecanoic and 12-methyl-(Z)-6-tridecenoic, in addition to the rare 13-methyl-(Z)-4-tetradecenoic. Su. mssa contained mainly 5,9dienoic and trienoic demospongic acids. For the first time, 2-hydroxy long-chain fatty acid methyl esters were analyzed by gc-Ft-ir, and the corresponding N-acyl pyrrolidide derivatives by gc-ms.
