<![CDATA[Cinnamomum burmanii (Nees n’ Th. Nees) Blume, Cinnamomum culilaban (L.) J.S. Presl dan Cryptocarpa massoy (Oken) Kosterm are a rare plant species that grow in Indonesia. Species with this same of genus (Cinnamomum) is a potential in the field of medicine, but the comparison of the composition and concentration of the chemical content has not been known so their utilization in medical applications is not optimal. Therefore, the research was conducted in order to analyze of chemical compounds in ethyl acetate extracts phase of three plants by chromatography, They were the HPLC (High Performance Liquid Chromatography), and GC-MS (Gas Chromatography Mass Spectrometry) analysis. The analysis was done of the ethyl acetate extract phase in order to identify of chemical compounds which largely composed of essential oils. Based on the results of HPLC analysis, with using by the reference standards of eugenol showed that in Cinnamomum burmanii and Cinnamomum culilaban (L.) J.S. Presl identified contain of eugenol essential oils, 0.18% and 3.11% respectively. Based on the result of GC-MS analysis, Cinnamomum burmanii was found two components of chemical compounds main with the largest og percentage, They were sinamaldehid (90.24%) and coumarin (53.46%) compounds. On the Cinnamomum culilaban (L.) J.S. Presl was found four components of chemical compounds main, They were metileugenol (40.68%), verbanone (14.58%), terpinol (8.74%) and spathulenol (8.12%) compounds. Later in the Cryptocarpa massoy (Oken) Kosterm was found three components of chemical compounds main, They were massoyalakton (73.64%), butanoat acid (12.25%) and pentadekanoat acid (9.76%) compounds.]]>
