Chemical composition of essential oils from aerial parts of Cinnamomum malabatrum (Burman f.) Bercht & Presl.

Abstract

The constituents of the essential oils of leaf, petiole, shoot and terminal shoot of C;nnamomum malabatrum were determined by GC and GC- MS. Thirty-nine compounds, constituting 95% of the oil, were identified in the leaves. Major constituents of the leaf oil were (E)-caryophyllene (28.6%), (E)-cinnamyl acetate (115.1%), bicyclogermacrene (14.4%) and benzyl benzoate (8.5%). Twenty-eight compounds, representing 98% and 97% of the oil, were identified in the petioles and shoots, respectively, whereas in the oil of the terminal shoots 34 compounds, accounting for 97%, were identified. The essential oils of the petioles, shoots and terminal shoots were dominated by linalool (77.8- 79.4%). This is the first report of the essential oil constituents of C. malabatrum.
