Ganoderma lucidum ( G. lucidum ) is a mushroom‐forming white rot fungus. Although not edible, it is grown commercially for use as a medicinal supplement. In this study, G. lucidum was utilized for the extraction of polysaccharides by hot compressed water at temperatures of 373–463 K and a pressure of 4.0 MPa using a semibatch system—a most effective method because water at high temperature and pressure behaves as a reaction medium with remarkable properties. Under these conditions, thermal softening of G. lucidum occurred, allowing the removal of the polysaccharides protecting other constituents in G. lucidum via hydrolysis. The main massed peaks of water‐soluble products were distributed at around 688–2638 m / z with a peak‐to‐peak mass difference of 162 m / z , consistent with the repeating unit of the glucans. On the basis of these results, this process is proposed as applicable to the isolation of polysaccharides from other types of biomass and may lead to an advanced plant biomass components extraction technology. © 2013 Curtin University of Technology and John Wiley & Sons, Ltd.
