Chemical Analysis of Essential Oil from the Leaves of Eugenia argentea Bedd

Abstract

The essential oil obtained by hydrodistillation of the leaves of Eugenia argentea was analyzed by GC and GC/MS. Thirty-five constituents comprising 98.5% of the oil were identified. The leaf oil was characterized by the abundance of three major classes of sesquiterpenoids, viz. caryophyllanes, cadinanes and germacranes. β-Caryophyllene (18.0%), δ-cadinene (7.8%) and germacrene-D (7.1%) were the major constituents in the leaf oil. No monoterpenes were detected in the leaf oil
