Chemical Composition of Essential Oils from the Needles and Branch of the Abies delaveyi Franch subsp. fansipanensis (Q. P. Xiang&al) Rushforth in Lao Cai Province
Main Article Content
Abstract
The essential oils from the needles and branch of the Abies delaveyi
subsp. fansipanensis was collected in Hoang Lien Natural Park, Lao Cai province and was obtained by steam distilation and the yields of essential oils were 0.27% and 0.08% from air-dry material. By the using GC/MS analysis, there are 44 and 52 constituents from needles and branch were identified and accounting 97.75% and 96.86% essential oil. The main constituents of needles essential oil were α-pinene (22.28%), β-phellandrene (17.80%), β-pinene (7.87%), α-cadinol (6.53%), myrcene (4.35%), δ-cadinene (4.39%). The main constituents of branchs essential oil were β-phellandrene (18.0%), α-pinene (10.95%), myrcene (10.76%), β-pinene (6.71%), abienol (6.71%). α-cadinol (3.31%). This is the first study on the chemical constituents of the essential oils from the needles and branchs of Abies delaveyi subsp. fansipanensis in Vietnam.
