Fomitoside K, a New Lanostane Triterpene Glycoside from the Fruiting Body of Fomitopsis nigra.

In an effort to identify the chemical constituents of fruiting bodies of Fomitopsis pinicola, a new lanostane triterpene glycoside, designated as fomitoside K, has been isolated from its methanolic extract. Its chemical structure was assigned on the basis of various spectroscopic studies. [ABSTRACT FROM AUTHOR]
