Ajuga reptans, phytoecdysteroids

Elbrecht et al. [167] reported that the iridoid glucoside 8-0-acetylharpagide (8-7), isolated from Ajuga reptans, possessed ecdysteroid agonist activity. Unfortunately, A. reptans is also a rich source of phytoecdysteroids and it is now clear that 8-0-acetylharpagide, per se, possesses no agonistic activity [168],...
