Abstract
The structures of two new triterpene acids isolated from Phellinus pomaceus have been determined by a combination of chemical and physical methods and confirmed by X-ray crystallographic analysis of one of their methylated derivatives. The compounds were identified as 4β,14α-dimethyl-3-nor-5α-pregn-8-ene-4α,20α-dicarboxylic acid and 4β, 14α-dimethyl-20-oxo-3-nor-5α-pregn-8-ene-4α-carboxylic acid.
