Ecdysteroid Profiles of Two Ajuga species, A. iva and A. remota

Phytoecdysteroids are plant analogues of insect moulting hormones and are used by plants to repel or disturb phytophagous insects. They are also active on mammals and present in many plants used in traditional medicine. The Ajuga genus contains several such species, which occur in various pharmacopo...

Description
Summary:Phytoecdysteroids are plant analogues of insect moulting hormones and are used by plants to repel or disturb phytophagous insects. They are also active on mammals and present in many plants used in traditional medicine. The Ajuga genus contains several such species, which occur in various pharmacopoeias. We report the isolation and identification of major and minor ecdysteroids present in two Ajuga species, A. iva and A. remota, both of which are used as medicinal plants in Africa. Three minor ecdysteroids (abutasterone, ponasterone A and sidisterone) have been found for the first time in the Ajuga genus.
