Study on Terpenoid Compounds of Different Tissues of Camphor Tree

Abstract

Abstract. Based on the current research value of biomass and terpenoids, in this paper, the terpenoids contented in the different organizational of the camphor tree were analyzed by SDE extract method and GC-MS analysis method. The results showed that the contents of terpenoids contained in camphor leaves were the richest. The highest content of terpenoids in three tissues was camphor, especially the relative content of camphor in leaves got to 71.96%.In addition, except camphor, the higher terpeneoid compounds of the leaves respectively were carypohyllene (5.29%), α-pinene (4.06%) and limonene (2.87%). The higher terpeneoid compounds of the branches respectively were α-pinene (2.33%) and carypohyllene (1.78%). The terpenoids contained in the flowers were ketone terpenes, respectively, 2, 3-acetylacetone (1.33%) and propyl methyl ketone (1.25%). This paper provides the basis for the extraction and utilization of terpenoids in camphor trees, which lays a foundation for the further study of the application value of natural terpenoids in camphor trees.
