Hexahydrofarnesylacetone (6,10,14-trimethylpentadecan-2-one, 1) is a widespread ketone occurring in plants and insects. Several species use this compound or the respective alcohol as part of their pheromone bouquet. Here, we showed by using deuterium labeled phytol (3) and GC-MS experiments that the Large Cabbage White butterfly Pieris brassicae can take up phytol in the larval stage and transforms it into 1 by oxidative degradation.
