Abstract
Verbenalin and a new iridoid, hastatoside (2) have been isolated from Verbena hastata and V. officinalis. The structure and absolute configuration of hastatoside has been determined by spectroscopical methods, and by correlating 2 chemically with verbenaline and the lactone 6. The lactone 7 has been synthesized from verbenaline. The name brasoside-tetraacetate is proposed for 7, since brasoside has been found in V. brasiliensis as a natural product.
