Here is our patented production method to produce highest quality Organic ganoderma reishi mushroom that has been published in the international journal of medicinal mushrooms and that we achieve by collaborating with the National Institute of Advanced Industrial Science and Technology, Higashihiroshima, Japan and National Institute of Advanced Industrial Science and Technology, Higashihiroshima, Japan; Graduate School of Life Science, Hokkaido University, Sapporo, Hokkaido, Japan .
Title: Production of Ginkgo Leaf–Shaped Basidiocarps of the Lingzhi or Reishi Medicinal Mushroom Ganoderma lucidum (Higher Basidiomycetes), Containing High Levels of α- and β-D-Glucan and Ganoderic Acid A
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.
