Essential Oils from Bolivia. IX. Asteraceae:<i>Plazia daphnoides</i>Wedd

Abstract

Abstract The chemical composition of the essential oil obtained from Plazia daphnoides growing in the High Valley Region of Bolivia, Province of Cochabamba, was determined by a combination of GC and GC-MS measurements. The composition of the oil was dominated by oxygenated sesquiterpenes (33 %) and sesquiterpenes (30 %): T-cadinol and β-caryophyllene were the main components (10–11% each) followed by epi-α-bisabolol (9 %). Oxygenated monoterpenes accounted for 14 % and monoterpenes for 11%.
