This research tries to compare terpene compounds of five species of coniferous trees to find out which tree has relatively high–concentrated terpene compounds, and to check their concentration by season to find out which season the concentration is the highest. In addition, it tries to find out whether terpene compounds in the leaves are actually volatilized into the atmosphere. The results of the research show that there were no relatively high–concentrated terpene compounds in the leaves of Pinus densiflora and Pinus koraiensis, compared to the others. However, when the concentration of terpene compounds, which are volatilized in an airtight container, was checked, relatively high–concentrated terpene compounds were volatilized: 8 kinds of terpene compounds in the leaves of Pinus densiflora; 16 in Pinus koraiensis; 10 in Abies holophylla; 1 in Chamaecyparis obtusa; 2 in Chamaecyparis pisifera. And the concentration of terpene compounds by season was checked, the concentration of 21 terpene compounds was high in spring, excluding those of Abies holophylla, which showed high concentration in summer. The concentration of the terpene compounds by substance was generally high in spring and summer. Therefore, it is more effective to extract essential oil from coniferous trees in spring and summer.
