Essential Oils from Bolivia. XI. Verbenaceae :<i>Aloysia gratissima</i>(Gillies &amp; Hook.) Tronc. and Boraginaceae :<i>Cordia chacoensis</i>Chodat

Abstract

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 (be- tween 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 %).
