- Abstract
Two new iridoids, 6- O-[( E)-feruloyl]jioglutin D ( 1) and 6- O-(4-hydroxybenzoyl)jioglutin D ( 2), and six known compounds, minecoside ( 3), specioside ( 4), picroside II ( 5), picroside III ( 6), 4-hydroxybenzoic acid ( 7), and martynoside ( 8), were isolated from the stem of Catalpa ovata. The structures of the new compounds were established on the basis of spectroscopic techniques, including 1D- and 2D-NMR.
