Through literarure survey, sesquiterpenes were found to be the predominant class in the
essential oil of most of genus Cordia. José, et al assumed that we can use sesquiterpenes as taxonomic markers for the future identification of Cordia species.(3) In this paper, we analyze
this assumption through in-depth data analysis (table 3, 4). These analyses permits one to
observe qualitative and quantitative differences between essential oils of different Cordia
species.
