Chemical Composition of the Essential Oil and Petroleum Ether Extract from Korea Pine Needle Leaves of Cedrus deodara

초록

The composition of the pine needles leaves of Cedrus deodara essential oil and petroleum ether extract of Gwangjin-gu region of Seoul; Korea Were Obtained by hydrodistillation and extraction, respectively analyzed by gas chromatography-mass spectrometry (GC-MS) The essential oil yield was (020 %, w/w) of leaves. Thirty eight and forty components comprising 99.2 and 993 % of the total peak area were identified in the essential oil and petroleum ether extract, respectively. Essential oil major components were dominated by: alpha-pinene (2.9 %) alpha-myrcene (9.9 %), dl-limonene (3.9%), trans-caryophyllene (4.2 %), alpha-humulene (34 %); linalyl propionate (10.9 %); delta-cadinene (2.7 %), caryophyllene oxide (2.8 %), 1-dodecanol (2.9 %), alpha-cadinol (3.9 %), t-muurolol (4.4 %), dodecanoic acid (129 %). Petroleum I ether extract Major components were dominated by butyl acetate (33.9 %), 4-allyloxy-2-methyl penta-en-2-ol (6.2 %), 2,2-dimethyl pentanal (2.4%), alpha-pinene (2.92 %), 2-methyl-5-phenyl-5-pentanonenitrile (2.7 %), benzoic acid (2.7 %), ethyl ester of dodecanoic acid (6.1 %), butyl ester of 5-oxohexanethioic acid (2.5 %), caryophyllene oxide (6.8 %). The identity of components of essential oil and petroleum ether extract Was confirmed on the basis of retention time mass and supplemented library of NIST, USA. The essential oil and petroleum ether extract constituents are identified for the:first tithe in Korean C. deodara pine needle leaves
