The compositions of the essential oil of the aerial parts of Aloysia gratissima and Cordia chacoensis are almost similar. In both cases, oxygenated sesquiterpenes constituted the main group (between 40 and 50 %): 6α-hydroxygermacra-1(10),4-diene being the major compound (~ 16 %). Sesquiterpenic molecules constitute the second important group (30 -34 %) with β-caryophyllene as the major compound (8.0 %).

The chemical composition of the essential oils of Myrcianthes osteomeloides and M. pseudomato was studied by GC and GC/MS. Myrcianthes osteomeloides oil contained 1,8-cineole (55.7%) as the major component followed by α-pinene (17.9%), α-terpineol (8.5%) and β-pinene (4.6%). We identified 1,8-cineole (24.4%), α-pinene (17.1%), linalool (11.7%), limonene (8.5%) and γ-terpinene (7.3%) as main constituents in M. pseudomato oil.
