„The wood oil of Fokienia hodginsii L. is separated by distillation, column and gas-liquid chromatography. At least 35 constituents are detected, 24 of which are identified and 3 are structurally evaluated. Main constituents (24% each) are nerolidol and the hitherto unknown 2,6,10-trimethyldodeca-1,3-trans(s-trans)6-trans, 11-tetraene-10-ol (fokienol).“

fokienol

Reinvestigation of the Vietnamese wood oil of F.hodginsii L. gave nearly the same composition and percentages as reported in 1971. The oil contains exclusively sesquiterpenes with (E)-nerolidol (35%) and fokienol (26%) as main constituent. Repeated flash chromatography of a polar fraction gave a mixture of β-eudesmol, α-cadinol and dauca-8(14),11-dien-9-ol (3%, biogenetic key compound).
