Research progress of germplasm resource utilization and medicinal active components of Ganoderma tsugae
Ganoderma tsugae,a significant medicinal fungus,has abundant germplasm resources and various bioactive substances,having a long collection and utilization history in China.This paper is the research progress of the germplasm resources and bioactive substances of G.tsugae.G.tsugae is mainly distributed in the northeast region of China.Its artificial cultivation mainly adopts cut-log cultivation mode,using the wood of larch and Mongolian oak as culture medium.Significant achievements have been made in biomimetic cultivation under forest,wild cultivation under forest,greenhouse cultivation and other modes.G.tsugae is rich in active ingredients such as polysaccharides,terpenoids,and sterols,among them polysaccharides and triterpenes are important.Previous studies have shown that they can enhance the body's immune function,inhibit tumor cell growth and metastasis,and have protective effects on the cardiovascular and cerebrovascular systems.Further research should focus on the extraction and purification of active ingredients,exploration of pharmacological mechanisms,and improvement of artificial cultivation techniques in order to achieve their more wide-ranging development and utilization.
