-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 [[http://www.pherobase.com/database/kovats/kovats-detail-fokienol.php|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%) as a biogenetic key compound. \\

+"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 ([[http://www.pherobase.com/database/kovats/kovats-detail-fokienol.php|fokienol]])." \\

+"Fokienia hodginsii (Dunn) Henry et Thomas produces a sesquiterpene-rich oil, whose composition has been  investigated by a combination of chromatographic and spectroscopic techniques. The three samples analysed, two from Vietnam, the third of unspecified origin, exhibited an oxygenated fraction much more important than the non-polar fraction. (E)-Nerolidol and fokienol, two acyclic sesquiterpene alcohols, were the major components (24-35% and 24-26%, respectively). A few oxygenated compounds, such as α-, β- and γ-eudesmols, α-cadinol and elemol, were present at appreciable contents. Other oxygenated sesquiterpenes differed from sample to sample. Conversely, a few sesquiterpene hydrocarbons were reported in the three samples of F.hodginsii essential oil: δ-cadinene (3.7-6.5%), γ-cadinene (2.3-4.5%), α-muurolene (1.8-2.5%), β-elemene (0.1-0.3%)." \\
