ABSTRACT: In the present
investigation, we studied new essential oil contents and compositions of three
individual plants from Cupressaceae family cultivated in Vietnam. The air-dried
plants were hydrodistilled and the oils analysed by Gas chromatography (GC)
and Gas chromatography couples with Mass spectrometry (GC-MS). The components
were identified by comparison of their retention indices on HP-5 MS capillary
column with literature reference and MS pattern with authentic library’s
collection. a-Pinene (36.0%), α-cedrol
(18.3%) and thujopsene (5.7%) were the main constituents of Cupressus tonkiensis Silba. Monoterpenes
were the quantitative significant compounds of Sabina chinensis (L.) Antoine. These are bornyl acetate (19.5%),
sabinene (17.3%) and a-pinene (15.8%). Moreover, the
main compounds of Thuja orientalis L.,
were identified as a-pinene (34.1%), α-cedrol (16.5%), β-caryophyllene
(5.4%) and β-selinene (5.2%). The
chemotaxonomy implication of these results was also discussed.
