Abstract
Three new prenylated flavones were isolated from the aerial parts of Neorap utia paraensis. On the basis of spectral data these flavones were identifie d as 5,7,5'-trimethoxy-6-(3"-hydroxy,3"-methyl-trans-but-1"-enyl)-3',4'-met hylenedioxy-flavone; 5,4'-dihydroxy-3',5'-dimethoxy-6,7-(2",2"-dimethylpyra n)flavone and 5,4'-dihydroxy-8,3',5'-trimethoxy-6,7-(2'',2"-dimethylpyran)f lavone.
