Hericium erinaceus, also known as lion’s mane mushroom, is an edible and medicinal mushroom that belongs to the family Hericiaceae. We previously reported hericene A as an anti-diabetic constituent of H. erinaceus and the effect of cultivation substrates on its content was investigated. As the continuation, the contents of five major compounds such as hericenes A-D, which exerted α-glucosidase inhibitory activity, together with ergosterol were investigated depending on cultivation stages. H. erinaceus was cultured for 25 days (5 stages) to induce fruiting bodies, and the contents of the compounds at each stage were quantified. All the five compounds were detected in fruiting body by HPLC analysis. Among the hericene derivatives in the mushroom, the content of hericene A was the highest, followed by hericene C and the content of hericenes B and D was relative low. All four hericene derivatives present in the highest content at stage 4 whereas the content of ergosterol was highest at stage 5. The highest α-glucosidase inhibitory activity of H. erinaceus was measured at stage 4, which correlates with the contents of hericene derivatives. Conclusively, H. erinaceus with better efficacy and high content of active constituents can be secured by the optimization of cultivation conditions.
