摘要
In the original publication of the article,the section`Conclusions’was not included.The paragraph is given below.Conclusions As determined various fungi live on Caucasian Alder trees including Ganoderma applanatum,Lenzites betulina,Trichaptum biforme,Rigidoporus ulamrius,Fomes fomentarius,Schizophyllum commune,Auricularia mesenterica,and Trametes versicolor.The highest amounts of betulin and betulinic acid were obtained in Ganoderma applanatum(3.642%)and Schizophyllum commune(1.413%),respectively.The lowest amount of both compounds were in L.betulina.All tested fungi had high antioxidant activity.The highest amounts of phenol(719.993 mg/ml)and fl avonoids(361.403 mg/ml)were found in the ethanolic solvent associated with G.applanatum fungus.It seems that due to high growth rate of fungi,low production cost and the special benefi ts of betulin and betulinic acid in particular,there is a good prospect for the production of various drugs from these resources.
