IRIDOIDS IN VERBENA

Abstract
Summary: Several species of Verbena were examined for iridoid glucosides. These were found in all species of subgenus Verbenaca investigated. In two of three species of the group Pachystachyae the iridoid glucoside griselinoside was detected, while all species from the group Leptostachyae contained mixtures of cornin and the closely related hastatoside. The species from subgenus Glandularia only occasionally contained iridoids, and in no case were the compounds from subgenus Verbenaca detected.
