Abstract
The co-feeding experiment of leucine-4,5-3H and mevalonic-2-14C acid corroborated the preferential localization of radioactivity on the 3,3-dimethylallyl pyrophosphate-derived moiety of linalool in its biosynthesis from radioisotopically labeled leucine by cinnamomum Camphora Sieb. var. linalooliferum Fujita, in contrast to the predominant location of the activity on its isopentenyl pyrophosphate-derived moiety in the biosynthesis from mevalonic acid. Also, it was established that the imbalance in the localization of radioactivity is not influenced by exogenous administration of leucine or inhibition of isopentenyl pyrophosphate isomerase.Keywords
