Abstract

The leaves of Tecoma chrysantha JACQ. a tree of the tropics, contain together with 6-epiaucubin (1), a less polar iridoid 2. Chemical and spectroscopical data demonstrated that 2 contains a residue of 1 esterified by 8-hydroxy-2,6-dimethyl-2,6-octadienoic acid (3), a rare monoterpenic product.
