Advances and challenges in polysaccharide extraction from the woody structure of fruiting bodies of Reishi mushroom, Ganoderma lucidium

Polysaccharides are one of the key bioactive compounds present in Reishi mushroom, Ganoderma lucidium. Therefore, it is necessary to provide an up-to-date comprehensive outline of the advances in the field of polysaccharide extraction from G. lucidium and to better understand the obstacles and advantages of the different methods. Thus, this review has combined conventional and modern methods developed since the year ۲۰۰۰ and has compared them with regard to their advantages and disadvantages. A search was conducted in Scopus, PubMed, and Google Scholar, databases for articles published between the years ۲۰۰۰ to ۲۰۲۳ using the following keywords: Reishi mushroom, G. lucidium, polysaccharide, beta glucan (β-glucan), and extraction. The association between the obstacles of polysaccharide extraction and the special cell structure of fruiting bodies of G. lucidium has also been discussed. This review also demonstrates how the integration of modern extraction methods and the use of appropriate statistical evaluation methods may create the potential to improve the efficiency of polysaccharide extraction.
