Abstract The chemical composition of the leaf oil of camu-camu (Myrciaria dubia (HBK) McVaugh) was studied by GC and GC/MS. One hundred and fifteen components of the oil were identified, of which Î±-pinene (74.3%) and limonene (10.8%) were the major constituents. The composition of the leaf oil was characterized by its richness in monoterpene and sesquiterpene hydrocarbons and the presence of many esters and unsaturated aldehydes Key Word Index: Camu-camu Myrciaria dubia Myrtaceaeessential oil compositionÎ±-pinenelimonene
