title: Dihydrospinochalcone-a and epi-flemistrictin-B, natural isocordoin derivatives from the root extract of Lonchocarpus xuul.
abstract: Purification of the root extract of Lonchocarpus xuul resulted in the isolation and identification of dihydrospinochalcone A (1) and epi-flemistrictin B (2) as additional natural isocordoin derivatives. Identification was based on the analysis of their spectroscopic data and by comparing these with those of previously reported metabolites.
