Cellulose acetate membrane electrophoresis and FTIR spectroscopy as methods of identifying a fucoidan in Fucusvesiculosus Linnaeus.
A fucoidan from brown algae such as the common bladder wrack (Fucusvesiculosus Linnaeus) is now widely examined in many countries for its interesting biological and therapeutic properties. In this study, the fucoidan was identified during extraction in hydrochloric acid; its presence was confirmed by FTIR spectroscopy. Two slightly different structures were found in real samples of dried bladder wrack supplied by Flos and Witherba, by comparing them with a reference sample of F. vesiculosus L. A simple, repeatable analytical procedure was developed using apparatus for cellulose acetate membrane electrophoresis and this was supplemented by semi-quantitative analysis.
