Aromatic Plants of Tropical Central Africa IV. Essential Oils ofEupatorium odoratumL. from Cameroon and Congo

Chemical Composition of the Essential Oils of Aerial Parts and Flowers ofChromolaena odorata(L.) R. M. King & H. Rob. from Western Ghats Region of North West Karnataka, India

“…C. odorata is a medicinal plant having diverse pharmacological properties such as antihelmintic 8 , antigonorrhoeal 9 , diuretic 10 , analgesic 11 , anti-inflammatory 12,13 , antipyretic, antispasmodic 13 , wound healing 14 activities and antimicrobial properties 15,16 . The chemical compositions of the essential oils of C. odorata have been reported to possess α-pinene and p-cymene from Cameroon and Congo 17 , from Nigeria α-pinene, β-pinene, germacrene D, β-copaen-4α-ol, β-caryophyllene, geijerene and pregeijerene 18 , α-pinene, cadinene, camphor, limonene, β-caryophyllene and cadinol isomer 16 , from Thailand pregeijerene, germacrene D, α-pinene, β-caryophyllene, vestitenone, β-pinene, δ-cadinene, geijerene, bulnesol, and transocimene 19 , while from Ivory Coast α-pinene, geijerene and pregeijerene 20,21 as the major constituents.…”

“…Previous peports illustrated that the essential oil composition of C. odorata have been examined from different countries [16][17][18][19][20][21] . Though, report from India is inadequate concerning terpenoid profile of this plant.…”

“…Also, α-pinene, β-pinene, geigerene, pregeijerene and germacrene D have been isolated from fresh leaves of C. odorata in Benin Republic (Avlessi et al, 2012). Lamaty et al (1992) isolated p-cymene and α-pinene from C. odorata collected from Congo and Cameroon. Joshi (2013a) isolated some essential oils from the aerial parts and flowers of C. odorata in India including khusimone, α-muurolol, geijerene, pregeijerene, cyperene, germacrene D, δ-cadinene, epi-cubebol, cubebol, cis-sabinene hydrate, 10-epi-γ-eudesmol and germacrene-D-4-ol.…”

Headspace solid-phase microextraction gas chromatography–mass spectrometry analysis of Eupatorium odoratum extract as an oviposition repellent

“…Terpenes amounted to 88% of the oil, which was characterized by the presence of pregeijerene (14%) and geijerene (5%) [13]. Lamaty et al studied the chemical composition of the essential oils that were obtained from the leaves of E. odoratum collected in Cameroon and Congo [14]. Inya-Agha et al found some components including tannins, phenols, pinene, cadinene, camphor and limonene in the essential oil of E. odoratum, which had an antibacterial effect [15].…”

“…To the best of our knowledge, only some researchers have studied the essential oil of E. odoratum [10,[12][13][14][15][16][17]. Chowdhury studied the essential oils obtained from the leaves of E. odoratum collected from Shillong Meghalaya, North-East India and found that the oil contained mainly caryophyllene oxide (18.34%) [12].…”
