The essential oil occurring in the patchouli (Pogostemon cablin) plant is stored in special glands of the leaves. There it accumulates large amounts of its main component (-)-patchoulol that can be extracted by steam distillation [Deguerry06]. The pleasant fragrances in this oil make it an important ingredient in commercial production of cosmetic products [Weyerstahl89] [Frater98]. The oil composition is complex and the main constituents are sesquiterpenoids. The biosynthesis of (-)-patchoulol and derivatives thereof, i.e. α-patchoulene β-patchoulene, γ-patchoulene and seychellene is depicted in the above pathway [Deguerry06] [Munck90].
The multifunctional enzyme patchoulol synthase catalyzing the convertion of (2E,6E)-farnesyl diphosphate into the various, structural very similar sesquiterpenoids is known to produce almost the whole fragrance cocktail of about 13 different sesquiterpenoid compounds reported in Pogostemon cablin [Deguerry06].
