Activities of Antioxidation and AChE Inhibition of Extract from Hericium erinaceus

It has been known that the novel diterphenoids, hericenone and erinacine isolated from the fruiting body and cultured mycelia of Hericium erinaceus showed potent stimulating activity of nerve growth factor (NGF)-synthesis. To investigate the biological activities of extracts from fruiting body, cultured mycelium and cell-free broth of H. erinaceus, the activity experiments of antioxidation and AChE inhibition were carried out. Sephadex G-10 gel filtration followed by HPLC on a ${\mu}Bondapak$ $C_{18}$ column of EtOAc extract from cultured mycelium showed a biological activity.
