Abstract

In this study, the chemical composition of the essential oil of Orthosiphon diffusus was investigated. Extraction by hydrodistillation followed by gas chromatography and mass spectrometry (GC-MS) yielded 25 compounds representing 95.3% of the oil. The major volatile components of the oil were n-eicosane (19.5%), t-caryophyllene (18.6%), octocosane (12.2%), limonene (11.6%), β-ocimene (4.2), methyl palmitate (2.8%) and elemol (2.6%).

 

Key words: Orthosiphon diffusus, essential oil, n-eicosane, t-caryophyllene.
