ABSTRACT

The volatile components of the leaf, twig and the stem bark of Prunus Arborea var densa were investigated using a combination of GC, GCMS and HS-SPME/GCMS. The emitted volatile fractions from the different parts were analysed using HSSPME/ GCMS while the essential oils were obtained by hydrodistillation method. The main components found in the leaf oils were E, E-α -farnesene (23.9%), benzaldehyde (23.7%) and Z-hexenyl benzoate (11.2%). The twig oil was made up of benzaldehyde (15.4%), benzyl benzoate (12.9%) and benzyl salicylate (6.5%). The stem bark was mainly made up of benzoic acid (17.2%) with small amounts of benzaldehyde (1.6%). However, rapid chemical analyses of the plant parts using HSSPME/ GCMS showed presence of higher amounts of benzaldehyde (>80%) in the stem bark and twig parts when compared to the leaf parts. Overall, it was shown P. Arborea var densa could be a new natural source of benzaldehyde and other phenylpropanoids for uses as flavor, perfumery and herbal ingredients.
