Abstract
The content, infrared spectroscopy, total sulphate and optical rotation of the phycocolloid
from Laurencia papillosa (Forssk.) Grevüle from Tanzania have been investigated. A
phycocolloid yield of 33.6 ± 0-6% was obtained on a dry weight basis. The total sulphate
content of the phycocolloid was 16.8 ± 0.4% and the optical rotation was found to be
negative [a|D5 - 5.5 °. The phycocolloid was soluble in potassium Chloride. Its IR spectra
showed absorptionpeaks more akin to -than -or -cairageenan. A detailed discussion of these
findings is presented.
