Hemicellulose is the second most abundant plant polysaccharides after cellulose. Due to the non-toxicity, abundance and biodegradability, recently more and more attention has been focused on the exploration of hemicellulose as the potential substrate for the production of liquid fuels and other value-added chemicals and materials in different fields. Especially in the pharmaceutical and medical field, hemicellulose currently has aroused growing concern in immune regulation, bacteria inhibition, drug release, anti-caries, scaffold materials and anti-tumor because of its unique special physiological characteristics including biocompatibility, inhibiting cell mutation and anti-cancer effect, etc. In this paper, we introduce the application of nature hemicellulose, its degradation products, its derivatives and hemicellulose-based materials in the medical field. Their properties and use effects are also discussed in detail. Moreover, the extraction technologies of nature hemicelluloses, the preparation of hemicellulose-derived products are reviewed here briefly. The recent trends and perspectives of future development are highlighted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
