Grazielia

2.1. Genus Grazielia Four species of Grazielia were sampled and analyzed in this study. 68 compounds were identified in the VOs obtained from the species in this genus, amounting to 87.6–99.9% of the VOs. All the VOs obtained from the leaves and/or inflorescences of the species in this genus were characterized by the predominance of hydrocarbon monoterpenes (63.8–80.1%) with the same compounds being identified among the major constituents of all the samples. In the VOs obtained from the branches of G. nummularia (Hook. & Arn.) R.M.King & H.Rob a lower percentage of monoterpenes was present.
