Clustering of some Liquidambar orientalis samples according to essential oil compositions

摘要

Liquidambar orientalis have been used widely for traditional medicine in Anatolia, especially for wounding injuries. Chemical composition of 17 essential oil of Liquidambar orientalis leaves from different locations were studied using GC-FID. Similarity and the differences of the samples were determined depending on major component contents using Hierarchical Cluster Analysis (HCA) by MATLAB. 11 major essential oil in the samples were identified namely; α-Pinene, β-pinene, thujone-α, terpinolene, α-terpinene, γ-terpinene, 2-carene, terpinen-4-ol, α- terpineol, β-caryophyllene and germacrene-D, respectively. Locations and seasonal changes discriminated the Liquidambar orientalis samples from each other.
