Chemical composition of peel and leaf essential oils ofCitrus medica L. andC. limonimedica Lush.

Abstract

Five peel oils and six leaf oils of different varieties of citrons (Citrus medica and C. limonimedica) were obtained from fruits and leaves collected on trees submitted to the same pedoclimatic and cultural conditions. Their composition was investigated by capillary GC, GC–MS and Carbon-13 NMR. Three chemotypes: limonene, limonene/γ-terpinene and limonene/geranial/neral were observed for peel oils while leaf oils exhibited the limonene/geranial/neral composition.
