Volatile Constituents of the Flowers, Leaves, Stems and Roots of Tithonia diversifolia (Hemsely) A. Gray

Abstract

The chemical composition of the essential oils isolated by hydrodistillation from the flowers, leaves, stems and roots of Tithonia diversifolia have been studied by GC-MS. The identified components accounted for 96.7 %, 93.7 %, 88.9 %and 93.7 % of the flower, leaves, stems and roots oils, respectively. The major constituents of flowers, leaves, stems and roots oils were α-pinene (60.9 -75.7 %), δ-pinene (7.2–11.0 %) and limonene (0.9–4.3 %).
