ABSTRACT

Ganoderic acid A and α- and β-D-glucan content were compared among morphologically different basidiocarps of the medicinal mushroom Ganoderma lucidum. Ginkgo leaf-shaped basidiocarps gradually hardened from the base to the pileus and accumulated a higher amount of bioactive components than normal (kidney-shaped) and antler/deer horn-shaped basidiocarps. In the normal G. lucidum stipe, the outer context contained the highest amount of α- and β-D-glucan (approximately 55%) and the highest amount of ganoderic acid A (approximately 0.3%). Ginkgo leaf-shaped G. lucidum had a large area of outer layer and stout outer context, which contributed to their high α- and β-D-glucan and ganoderic acid A content.
