✦ Synopsis

The yield, IR spectra, 3,6-anhydro-D-galactose and sulfate content are given for several species of putative carrageenophytes from different sites on the Brazilian coast . Kappa carrageenan was found in Hypnea musciformis and Gigartina spp . ; all the other species tested yield an iota type . The lowest carrageenan yield was found in Cryptonemia crenulata (5 %), and the highest in Gigartina sp . (72 %) ; 3,6-anhydrogalactose content was highest in Hypnea musciformis and Gigartina spp ., whereas sulfate was lowest in H. musciformis . Slight variations in the yield of carrageenans were found during the period of observation (March 1988 to May 1989), but no clear pattern could be recognized . No significant variation was observed in plants from different collection sites .
