Abstract

Five new lanostane-type triterpenes, named fomefficinic acid A—E (1—5), were isolated from the dried sclerotium of Fomes officinalis, respectively. Their structures were established as 24-methylene-3-oxo-lanost-8-en-21-oic acid (1), 3α,15α-dihydroxy-24-methylene-lanosta-7,9(11)-dien-21-oic acid (2), 3α,15α-dihydroxy-24-methylene-lanost-8-en-21-oic acid (3), 15α-hydroxy-3-oxo-24-methylenelanost-8-en-21-oic acid (4), 15α-acetoxy-3-oxo-24-methylenelanosta-7,9(11)-dien-21-oic acid (5), by spectral analysis and chemical methods as well as comparison with known compounds.
