The hexane extract from the roots of Krameria cystisoides yielded besides conocarpan, licarin A, eupomatenoids 6 and 13, and ratanhiaphenol I 16 hitherto unknown lignans, neolignans and norneolignans, among them toltecol and olmecol.Structural elucidation was based mainly on spectroscopic investigations, especially 13C NMR. - Key Word Index: Krameria cystisoides; Krameriaceae; new lignans; neolignans and norneolignans.
