Essential oil composition of Strychnos axillaris Colebr. (Loganiaceae)

Abstract

The essential oil composition from the leaves of Strychnos axillaris Colebr. (Loganiaceae) growing in Malaysia was examined for the first time. The essential oil was obtained by hydrodistillation and fully characterized by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). In total, 15 components were identified in the essential oil, which made up 87.2% of the total oil. The essential is composed mainly of α-ionone (20.2%), β-ionone (19.5%), bicyclogermacrene (19.2%), and geranyl acetate (10.2%).
