Abstract

The 3H/14C isotope ratios in patchouli alcohol seychellene and cycloseychellene isolated from P. cablin that was fed with [4-3H1 (4R)14C]MVA suggests that these three sesquiterpenes are biosynthesized from a common intermediate and they are not interconvertible within the plant system. The results reveal that a stereospecific 1,2-methyl shift takes place during the formation of seychellene and cycloseychellene in vivo.
