Fucus evanescens

When Bilan et al. [26] fractionated the crude fucoidan of Fucus evanescens by ion-exchange chromatography on DEAE-Sephacel, using aqueous sodium chloride of increasing sodium chloride concentration as eluent, a fraction which was essentially a homofucan sulfate was isolated. This homofucan was shown to contain a linear backbone of alternating 3- and 4-linked-a-L-fucopyranose 2-sulfate residues. Also, some additional sulfation was observed on C-4 of the 3-linked residues, whereas a part of the remaining hydroxyl groups was randomly acetylated.

As already discussed for the phytoplankton, the distribution of the phytobenthos is also determined by the sahnity gradient. Therefore, its development is considered separately in the individual Baltic districts. Baltic species of marine origin are ecophy-siologically adapted to the lower salinity. The occurrence of endemic macrophytes is doubted. As data exist already from before 1880, the preindustrial reference conditions can be defined in some areas. In total, 48 out of the 422 listed species have not been found after 1970. This does not necessarily mean that species have disappeared as many of them are small ones which can be easily overlooked. Ten nonindigenous macro-phytobenthic species (e.g., Gracilaria vermiculophylla, Fucus evanescens) invaded the Baltic recently (Chapter 16).

The antitumor and antimetastatic activities of fucoidan from Fucus evanescens have been studied in vivo in C57B1/6 mice with transplanted Lewis lung adenocarcinoma. It was observed that single and repeated administration of fucoidan in dose of 10 mg/kg has exhibited moderate antitumor and antimetastatic effects and potentiated the antimetastatic, but not antitumor, activities of cyclophosphamide (Li et ah, 2008).
