Abstract: From the petroleum extract of Lonchocarpus atropurpureus Benth. roots, 5,2'-dihydroxy-3-methoxy-6,7-(2',2'-dimethylchromene)-8-(3',3'-dimethylallyl)-flavanone and 2',3,5-trihydroxy-6,7-(2',2'-dimethylchromene)-8-(3',3'-dimethylallyl)-flavanone were isolated, together with three known flavonoids and a mixture of two pentacyclic triterpenes. Their molecular structures were determined by spectral analyses (UV, IR, MS and 1D- and 2D-NMR experiments). (C) 1999 Elsevier Science Ltd. All rights reserved.
