Alkali extract obtained from mycelia of Lentinus edodes IY105 was shown to have potent anticomplementary activity and alternative complementary activity in vitro. It was also shown to activate reticuloendothelial system of ICR mice in the carbon clearance. Amount of carbohydrates and protein of the extract were 17% and 42% respectively. It was found that carbohydrates were consisted of 5 monosaccharides and protein was consisted of 16 amino acids. Antitumor activity was observed in the alkali extract treated group of sarcoma 180 bearing ICR mice.
