Lanostane Triterpenoids and Triterpene Glycosides from the Fruit Body of Fomitopsis pinicola and Their Inhibitory Activity against COX-1 and COX-2

Abstract

Two new lanostane triterpenoids (1, 2) and 10 new lanostane triterpene glycosides (3-12) have been isolated from the fruit bodies of Fomitopsis pinicola. Their structures were established primarily by NMR experiments and chemical methods, and their biological activity against COX-1 and COX-2 was investigated.
