| Abstract : | A new isoflavone named harpalycine and quercetin were isolated from the leaves and 3-hydroxy-4-isopentenyl-8,9-methyle-nedioxypterocarpan and betulinic acid from the roots of Harpalyce brasiliana. The structures were elucidated using spectroscopic methods, including 2D NMR techniques of the new isoflavone., |
