Identification of Volatile Constituents of the Stem bark and Fruits of Desmos cochinchinensis Lour

Abstract

The chemical constituents of essential oils obtained from the hydrodistillation of the stem bark and fruits of Desmos cochinchinensis Lour, were being reported. The combined techniques of gas chromatographyflame ionization detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) were employed in the analysis. The main compounds of the stem bark oil were -caryophyllene (16.9%), bicyclogermacrene (11.6%) and benzyl benzoate (10.1%) while the fruit oil was characterized by the abundance of -caryophyllene (20.9%), limonene (15.9%) and germacrene D (12.5%). The volatile contents of the stem bark and fruit of Desmos cochinchinensis have not been previously analysed and reported.
