Comparison between antioxidant activity and bioactive compounds of Ganoderma applanatum (Pers.) Pat. and Ganoderma lucidum (Curt.) P. Karst from Iran

Members of Ganoderma genus, belong to Basidiomycota, such as Ganoderma applanatum and Ganoderma lucidum have been noticed in traditional and modern medicine and pharmacology for their medicinal properties and bioactive compounds. The present study is undertaken to determine whether there is difference between chemical properties of G. applanatum and G. lucidum. The fresh mature fruiting bodies of fungi growing on common hornbeam (Carpinus betulus), were collected in Neka, a county in Mazandaran Province, Iran, and their antioxidant activity and bioactive compounds content were examined by spectrophotometer and HPLC method. According to the chemical analysis, the total phenols and flavonoids content, betulinic acid and also antioxidant activity measured by DPPH radical scavenging and FRAP methods in G. applanatum were higher than the other, but G. lucidum had higher content of total polysaccharides and proteins. Also the two other terpenoids (oleanolic acid and ursolic acid) were very low in these two fungi.
