Definition:A cyclopentapyran that is (4aS,7aR)-1,4a,5,6,7,7a-hexahydrocyclopenta[c]pyran substituted at position 1 by an oxo group and at positions 4 and 7 by methyl groups, respectively (the 4aS,7S,7aR-diastereomer). 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.
