The chemical composition of the essential oil obtained from Gnaphalium viravira 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 is dominated by non oxygenated terpenes. The main products are limonene, α-copaene, β-caryophyllene, geranyl-α-terpinene, and geranyl-p-cymene. Oxygenated monoterpenes account for less than 10%.
