Structural description

Lentinan is a polysaccharide obtained from Lentinula edodes (Berk./ Pegler, 1976) which is an edible mushroom popular in East Asia known as Shiitake. This mushroom is one of the most popular edible mushrooms in the world, production globally being second only to the button mushroom Agaricus bisporus.

Lentinan is a beta glucan and its structure is reported as a β(1-3) linked D-glucose with   β(1-6) branching point.

Activities and Uses

Lentinan interest is increasing because of its high nutritional value and medicinal properties, traditionally acknowledged by oriental cultures, especially in China and Japan.

Lentinan is attributed to have many functional properties such as antitumour and antiviral properties, as well as antimicrobial potential. Lentinula has shown neither evidence of being acutely toxic nor of having serious side effects.
