Chemical composition of the essential oils of Lantana camara L. occurring in south China

Abstract

Steam-distilled volatile oils from the leaves and flowers of Lantana camara L. were analysed by GC and GC-MS. The oils are characterized by a high percentage of sesquiterpenes. The main components detected are germacrene D (15.85%), β-caryophyllene (12.35%), α-humulene (9.31%) and germacrene-B (6.19%). 1,8-Cineole (4.61%), an oxygenated monoterpene is also reported. Experimental Plant Material and Extraction of VolatilesAerial parts of L. camara were collected from the campus of South China Agricultural University, Guangzhou, People's Republic of China, in August-September. Fresh leaves, flowers and thin branches were cut into 1-2 cm pieces, air-dried for 7 days at room temperature and steam-distilled for 5 h furnishing 0.13-0.2% (v/w) oils. The oils were dried over anhydrous Na 2 SO 4 and kept refrigerated until used. Analysis of the Essential OilsComponents of the volatile oil were separated on a Finnigan TRACE 2000 GC-MS instrument (FinniganSpectronex, USA), equipped with two fused-silica column (30 mm × 0.25 mm i.d.), coated with DB-1 (df = 0.25 µm); temperature programme, from 60°C (for 2 min) to 80°C at 3°C/min; 80-120°C at 6°C/min (held 0 min); 120-140°C at 3°C/min (held 0 min); then to 230°C at 10°C/min (held 0 min) and later, 240°C (held 1 min); injector temperature, 220°C; ion source temperature, 200°C; EI, 70 eV; carrier gas, He, 1 ml/min; injection volume, l µl; split, 1:20; mass range, 35-450 amu.

Essential oil from leaves of Lantana camara: a potential source of medicine against leishmaniasis

“…The germacrene-D was present in some EOLC analyzed (Sundufu & Shoushan, 2003;Da Silva et al, 1999;Khan et al, 2002) and the cariophylene groups were observed to be the only versatile components present in every EOLC analyzed by different authors (Ngassoum et al, 1999;Sefidkon, 2002;Rana, 2005), which is confirmed by the present work.…”

Chemical Composition, Antibacterial and Antioxidant Activities of Leaves Essential Oils from Syzygium cumini L., Cupressus sempervirens L. and Lantana camara L. from Egypt

“…10;2012 (3.22%), calarene (3.19%), ∆-cadinene (2.9%), α-pinene (2.11%) and trans-sabinene (1.09%). These results were in agreement with most published data like the South Chinese essential oil revealed by Sundufu and Shoushan (2004) where they found almost exact α-humulene (9.3%), higher 1,8-cineol (4.6%), lower sabinene (1.1%), lower α-pinene (0.8%), lower isomer β-caryophyllene (13.35%) and dominant higher germacrene D (15.9%) also higher germacrene D was found in other studies (da Silva et al, 1999;Möllenbeck et al, 1997). Recent study in Algeria reported that β-caryophyllene was dominant (35.7%) and lower α-humulene (3.72%), in L. camara oil (Zoubiri & Baaliouamer, 2011).…”

Possible mechanisms of action of the hypotensive effect ofAnnona muricata(soursop) in normotensive Sprague–Dawley rats

“…Essential oils such as β-caryophyllene, δ-cadinene, epi-α-cadinol and α-cadinol have also been isolated from the A. muricata plant (Pelissler et al, 1994;Kossouoh et al, 2007). Some essential oil like beta-caryophyllene present in other plants have been reported to exhibit hypotensive and vasodilator activities (Damiani et al, 2004;Sundufu & Shoushan, 2004;Morteza-Semnani, 2006;Kamboj & Saluja, 2008) and the presence of such compounds in A. muricata might possibly contribute to the cardiovascular effects observed with the aqueous plant extract (Abdalla et al, 1995).…”
