The essential oils of Chrysanthemum morifolium Ramat. from Nigeria

Abstract

The essential oils obtained by hydrodistillation from the flowers and leaves of Chrysanthemum morifolium Ramat. were analyzed by gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC/MS). Thirteen and twenty-one components representing 97.5% and 93.7% of the flower and leaf oil contents were identified respectively. The major constituents of flower oil were cischrysantheny acetate (21.6%), octadecanoic acid (19.5%) and borneol (15.5%). However, the leaf oil was characterized by borneol (20.5%), 1,8-cineole (15.2%), trans--bergamotene (14.0%), camphor (10.6%) and α-pinene (9.3%). This is the first report on the chemical composition of essential oils of Chrysanthemum morifolium from Nigeria.
