Composition of erinacine-A (E-A) and erinacine-S (E-S) within Hericium erinaceus mycelium crude extract (HE-CE) and their cytotoxicity in human SH-SY5Y cells. (a) High-performance liquid chromatography (HPLC) analysis of HE-CE content, shown with E-A and E-S standards. (b–d) Cytotoxicity of HE-CE (B), E-A (C), and E-S (D), as measured in human SH-SY5Y cells using the MTT assay. The cells were treated with HE compounds at various concentrations in a serum-free medium for 24 hours. ∗p < 0.05 between control/HE-CE (B), E-A (C), and E-S (D).
