Structural analysis of carrageenans from the tetrasporic stages of the red algae, Gigartina lanceata and Gigartina chapmanii (Gigartinaceae, Rhodophyta)

Clump structure, population structure and non-destructive biomass estimation of the New Zealand carrageenophyte Sarcothalia lanceata (Gigartinaceae, Rhodophyta)

“…This species is a carrageenophyte, with gametophytes and tetrasporophytes containing kappa-and lambda-type carrageenans, respectively (Pickmere et al 1975). The structure of the carrageenan from the tetrasporophytic life stage of S. lanceata is close to the idealised structure of lambdacarrageenan (Falshaw and Furneaux 1998), and has commercial potential as a thickener and stabiliser in food uses. The market for carrageenan-producing seaweeds continues to grow (Bixler and Porse 2011), but opportunities for the commercial use of wild seaweed stocks remain largely unexplored in New Zealand and collection is still managed under a permit system (see Hurd et al 2004).…”

HPLC Method for Microanalysis and Pharmacokinetics of Marine Sulfated Polysaccharides, Propylene Glycol Alginate Sodium Sulfate

“…The temperature of the column is maintained at 30 C and detected by UVD at 245 nm. To demonstrate that the proposed HPLC method is optimal, we employed a desulfurization strategy (Falshaw and Furneaux 1998) to overcome the influence of the sulfate group on the resolution of anomeric proton signals. We determined the M/G ratio of PSS by the NMR technique using its intermediate (low-molecularweight alginate) and desulfurization products.…”

Structural characterization of an anticoagulant-active sulfated polysaccharide isolated from green alga Monostroma latissimum

“…Desulfation of the sulfated polysaccharide was performed according to the method of Falshaw and Furneaux (1998). In brief, PML (30 mg) was dissolved in water and passed through an ionexchange column (731 resin, H + form), which was eluted with distilled water.…”
