Abstract

Phytochemical analysis of leaves from Enceliopsis nudicaulis, E. nudicaulis var. corrugata, and Geraea canescens afforded numerous methylated flavonoids present as resin constituents as well as benzofurans and related compounds extracted from roots. Five new dihydroflavonols present on the leaf surfaces were identified based on their spectral data and on those of the corresponding flavonols obtained by oxidation with NaHSO₃.
