Assay of Terpene Compounds Contained in The Tree for Forest Healing

Abstract

This study was conducted to find the properties of trees by comparing the terpene compounds of some species have different genetic characteristics. Terpene compounds contained in the leaves of the tree were analyzed qualitatively by headspace GC/MS method, and essential oils extracted in leaves by S.D.E. method were analyzed quantitatively by GC/MSD. According to the qualitative analysis result, there was no significant difference between conifers and hardwoods because of the 15-18 kinds of terpene compounds among the 19 kinds of terpene compounds investigated were detected in most of the species. However, the yield of oil extracted from cypress leaves was 9-10 times higher than hardwoods leaves and the yield of essential was higher in the order Chamaecyparis obtusa › Abies holophylla › Chamaecyparis pisifera › Pinus densiflora. As the quantitative characteristics of terpene compounds, the concentration of transcaryophyllene of essential oils was higher in the order A. holophylla › Lindera erythrocarpa › P. densiflora › Pinus koraiensis. The concentration of carene was significantly higher in A. holophylla and C. pisifera. The concentration of limonene was higher in the order C. obtusa › A. holophylla › C. pisifera, that of bornyl acetate was higher in the order A. holophylla › C. pisifera › C. obtusa. The concentration of camphene, myrcene and humulene was also the most highest in A. holophylla. Keywords: Abies holophylla, Chamaecyparis obtusa, Essential oil, Hardwoods, Oil yield, Terpenoids
