Chemical composition of the essential oils of the flowers, leaves and stems of two senecio polyanthemoides Sch. Bip. samples from South Africa



Chemical composition of the essential oils of the flowers, leaves and stems of two senecio polyanthemoides Sch. Bip. samples from South Africa



Molecules 14(6): 2077-2086



The essential oils of the flowers, leaves and stems of Senecio polyanthemoides Sch. Bip. Samples collected from two different localities within the city of uMhlathuze, KwaZulu-Natal Province (South Africa) were isolated by hydrodistillation and analyzed using GC and GC/MS. Twenty-six constituents were identified, representing an average of 86.0 - 99.6% of the total oil composition. The chemical profile reveals the dominance of monoterpenoid compounds, although some quantitative variance was noticed. The main constituents of the oils were limonene (3.1 - 43.0%), p-cymene (4.9-36.3%), beta-selinene (1.3-32.7%), alpha-pinene (1.8-21.4%), beta-pinene (7.6-16.5%) and 1,8-cineole (9.3-11.4%), caryophyllene oxide (4.1-13.4%) and humulene epoxide II (8.6-10.3%).
