[Extraction and analysis of gracilaria gigas Harvey polysaccharides].
Gracilaria Gigas Harvey Polysaccharides (GHPS) were extracted with hot water and sedimentated with ethanol. The amount of polysaccharides was determined by phenol-H2SO4 method. The mineral elements and molecular configuration were analysed by inductively coupled plasma (ICP) and infrared absorption spectrum (IR). The rate of distillation was 14.98%, the amount of polysaccharides was 78.2%, and GHPS contained manifold mineral elements (Ca, Fe, Mg and S). The IR spectra manifested that the extraction was a compound of polysaccharides, i.e. acidic polysaccharides.
