Abstract

Two new compounds, a compound firstly isolated from plants, a known iridoid and four known lignan derivatives were isolated from water extract of Tabebuia avellanedae. The chemical structures and relative configurations of the new compounds were determined by 1D, 2D NMR and MS spectroscopic analyses.
