Chemical composition of the essential oil of Diospyros wallichii King & Gamble (Ebenaceae)

Abstract

The chemical composition of the essential oil from the leaves of Diospyros wallichii (Ebenaceae) growing in Malaysia was investigatedfor the first time. The essential oil was obtained by hydrodistillation and fully characterized by gas chromatography (GC-FID) and gaschromatography-mass spectrometry (GC-MS). A total of 34 components (95.8%) were successfully identified in the essential oil whichwere characterized by high proportions of β-eudesmol (28.5%), caryophyllene oxide (9.5%), β-caryophyllene (7.2%), α-eudesmol(6.5%) and germacrene D (6.2%).
