We have identified a number of algae species with anticoagulant properties and report here on the anticoagulant activity of a crude sulfated galactan extracted from the red marine alga Halymenia floresia collected on the Atlantic coast of the state of Ceara, Brazil.
2000) that an addition of sulfate ester in a single unit of [alpha]--galactose and the molecular weight of the galactan have an amplifying effect on the prolongation of clotting time, a finding also reported for the algae Botryocladia occidentalis.
The chemical data indicated that early strength loss (up to 40%) was associated with loss of arabinan and galactan components.
They proposed a qualitative model in which early strength loss was initially a function of degradation in hemicellulosic side-chain components like arabinan and galactan (Fig.
2012) has reported the monosaccharide composition of AGAF is arabinose, galactose, glucose, and mannose, and identified AGAF as a type II arabinogalactan with [beta]-(1 [right arrow] 3, 1 [right arrow] 6) galactan backbone.
Aloe vera has high contents of pectic acid (70% to 85%), and in less proportion galactan, glucomannan and arabinan.
Galactan sulphate from Aghardhiella tenera (146) and xylomannan sulphate from Nothogenia fastigiata (147, 148) were found to be effective against human immunodeficiency virus (HIV), Herpes simplex virus (HSV) types I and II, respiratory syncytial virus (RSV) and so on.
Possibly this antimicrobial activity was observed to the presence of arabino galactan proteins and andrographolides in the ethanol extract of A.
