Fokienia hodginsii (Dunn) A. Henry & H. H. Thomas - syn.Cupressus hodginsii Dunn; Fokienia kawaii Hayata - Cupressaceae
福建柏 fu jian bai (chin.), Fujian cypress, Fujian-Zypresse, Fokienia, Siam-Holz
Evergreen tree, up to 30m tall, native to Vietnam and eastern China; lateral leaves almost as long as or slightly longer than facial leaves, straight, 5-10 × 2-3mm, on adult plants small, 2-7 mm, ridged and with a white, depressed stomatal band abaxially; pollen cones yellowish green, subglobose, 4-5 mm, seed cones brown when ripe; a vulnerable species in China.
Siam wood oil, huile bois de Siam:
„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).“

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).

„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%).“
