An iridoid monoterpenoid isolated from several Nepeta plant species. It is an aphid sex pheromone and cat attractant, and exhibits antibacterial, antifungal, and analgesic properties. It has a role as a pheromone, a plant metabolite, an insect attractant, an analgesic, an insect repellent, an antibacterial agent and an antifungal agent. It is an iridoid monoterpenoid and a cyclopentapyran."}]
