Advances in Research of Biological Activity, Action Mechanism and Structure - Activity Relationship of Lentinan.

Lentinula edodes is the second largest edible mushroom in the world and is widely used as food and medicine. Modern research shows that lentinan ( LNT) is the main active component of L. edodes. It has anti-cancer, treatment of diabetes, intestinal protection, anti-inflammatory, anti-oxidation, anti-aging, hepatoprotective, immune-regulating effects. In this review, the biological activity, action mechanism and structure-activity relationship of LNT in recent years are reviewed. On this basis, the existing problems were discussed, and the future research and application of LNT were prospected. Finally, it is hoped that this review will promote the in-depth study of LNT and provide a reference for its development as a drug and functional food. [ABSTRACT FROM AUTHOR]
