title: Three new triterpenoids from Fuscoporia obliqua.
abstract: Three new lanostane triterpenoids, fuscoporianol A (1), B (2), and C (3) were isolated from the petroleum ether extracts of Fuscoporia obliqua and their structures have been determined on the basis of chemical, spectroscopic methods and X-ray crystallographic analysis as 25-methoxy-21, 22-cyclolanosta-8-ene-3beta, 21alpha-diol(1), 3beta, 22alpha-dihydroxy-lanosta-8, 23E-diene-25-peroxide (2), 3beta, 22alpha, 25-trihydroxy-lanosta-8, 23E-diene (3).
