Analysis of the Essential Oils of Pine Cones of<i>Pinus koraiensis</i>Steb. Et Zucc. and<i>P. sylvestris</i>L. from China

Abstract

Abstract The chemical composition of the essential oil obtained from pine cones of Pinus koraiensis and Pinus sylvestris from northeast China was analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS), and 35 and 31 components were identified, respectively. α-pinene (35.2%), limonene (18.4%), β-pinene (8.7%), β-caryophyllene (3.5%) and myrcene (3.0%) were the main components in P. koraiensis cone oil. Aromadendrene (20.2%), α-pinene (18.5%), α-longipinene (10.5%) and α-terpineol (5.5%) were the main components in P. sylvestris cone oil. The antioxidant activity of the oils from P. koraiensis and P. sylvestris was evaluated using the DPPH.
