Abstract:

Fruit bodies of Phellinus linteus growing on 6 species of trees were compared for differences in contents of bioactive components including polysaccharides, total flavonoids and total triterpenoids. Results showed that there were significant differences in bioactive components in fruit bodies of Phellinus linteus growing on 6 species of trees. Fruit body of Phellinus linteus growing on mulberry tree exhibited contents of polysaccharides, total flavonoids and total triterpenoids of 3.84%, 5.12% and 2.2%, respectively, higher than those of fruit bodies of Phellinus linteus growing on other 5 tree species. The lowest polysaccharide content of 1.35% was observed in fruit body of Phellinus linteus growing on Syringa reticulata var.mandshurica Fruit body of Phellinus linteus growing on silver birch exhibited the lowest contents of total flavonoids and total triterpenoids, which were 0.68% and 0.32%, respectively.

Key words: Phellinus linteus, polysaccharides, flavonoids, triterpenoids
