Kesarin
editCadwallader [1], et.al., in 1997 reported on the aroma dilution analysis of saffron volatiles and found that a minor component, 2-Hydroxy-4,4,6-trimethyl-2,5-cyclohexadien-1-one (also isolated by Tarantilis and Polissiou from steam distillation of Greek red saffron), was the most powerful aroma constituent of saffron, followed by safranal. Its odor was descibed as "saffron, dried hay like". Interestingly, 2-Hydroxy-4,4,6-trimethyl-2,5-cyclohexadien-1-one is also the unique pheromone from the bark beetle, Ips pini known as Lanierone (Teale [2], et. al.).
2-Hydroxy-4,4,6-trimethyl-2,5-cyclohexadien-1-one Aroma: saffron, dried hay like.
