Extraction, isolation, identification, and bioactivity of polysaccharides from Antrodia cinnamomea

Abstract

Antrodia (A) cinnamomea is a precious edible and medicinal mushroom and has attracted attention because of its rare resources and unique bioactivities. The bioactive compounds from the fruit body, mycelium, and fermentation broth of A. cinnamomea include triterpenoids, polysaccharides, antroquinonols, benzenoids, and succinic and maleic acid derivatives. Among these, polysaccharides are very important and are high-content bioactive compounds. The A. cinnamomea polysaccharides (APSs) present numerous biological activities, such as antiviral, anticancer, anti-inflammatory, antivascular, immunoregulation, antioxidant, and nerve protection. However, only few studies have focused only on APSs so far. Therefore, the cultivation methods, extraction, isolation, composition, structure, biological activity, and application of APSs are summarized in this review to provide a comprehensive and convenient reference for further research and development on APSs.
