Antitumor Effects Over the past 30 years, previous studies have strongly suggested three possible ways by which G. frondosa exerts its anticancer effect—protection of healthy cells, prevention of tumor metastasis, and inhibition of tumor growth. In other words, G. frondosa can fight against tumors directly and indirectly via enhancement of the immune system. The antitumor activity [...]

Polysaccharides In the past 30 years, over 47 bioactive polysaccharide fractions have been isolated and purified from the fruiting body, mycelium, and cultured medium of G. frondosa using different extraction methods. G. frondosa contains 3.8% water-soluble polysaccharides on a dry weight basis, of which 13.2% was (1→3, 1→6)-β-D-glucan, and others include heteroglycan or the heteroglycan/protein complex. Among [...]
