Chemical composition and antidermatophytic properties of the essential oils from leaves, flowers and fruits ofCupressus lusitanica Mill. from Cameroon

“…More recent work 5 carried out on an oil sample from C. sempervirens collected in Dschang town in Cameroon revealed that it contains sabinene (14.8%), terpinen-4-ol (11.4%) and α-pinene (9.9%) as major components with 18 other constituents. In a similar work, Adams et al 2 reported that the essential oils from the leaves of C. benthamii and C. lindleyi contain high amounts of diterpenes and monoterpenes as well as sesquiterpenes. To the best of our knowledge, no report is available on the chemical composition of essential oils from fruits and flowers of C. lusitanica.…”

“…Adams et al, 2 analysing three oil samples from Portugal, showed that they contain monoterpenes, sesquiterpenes and diterpenes with abietadiene (11.3-24.4%) as the major component. Floreani et al 3 found α-pinene (11.2%), β-pinene (16.5%) and δ 3 -carene (19.4%) as major constituents with 27 other components in the leaf oil of this plant species.…”

Chemical composition and antidermatophytic properties of volatile fractions of hexanic extract from leaves of Cupressus lusitanica Mill. from Cameroon

“…The presence of diterpenes in the third fraction of this extract is a fact to be noted. Many of these compounds were described by Adams et al (1997) as constituents of the essential oil from the leaves of Cupressus lusitanica samples from Portugal. But these compounds do not appear in the essential sample we analysed (Kuiate, 2005).…”

“…The essential oil of the leaves is used against rheumatism, whooping cough, and styptic problems (Duke, 2004). The juice of the leaves is used in some areas of the Western Highlands of Cameroon to cure skin diseases The chemical analysis of three samples of this oil from Portugal showed that it contains monoterpenes, sesquiterpenes and diterpenes, with abietadiene as major component (Adams et al, 1997). In related studies, Floreani et al (1982) described ␣-pinene, ␤-pinene and ␦ 3 -carene as major constituents while to these components Carmo and Frazao (1989) added myrcene.…”

α-Pinene- and β-myrcene-rich volatile fruit oil ofCupressus arizonicaGreene from northwest Iran

“…Compositional analysis of the volatile oil of C. arizonica has been the subject of several studies conducted in the past. Adams, Zarioni, Lara, Barrero and Cool (1997) reported that the principal components of C. arizonica oil cultivated in Texas were diterpenes of phyllocladanol (14.2%) and nezukol (8.5%), as well as butyl methyl ether (8.6%) and -pinene (7.6%). Chanegriha, Baalioumer, Meklati, Chretien and Keravis (1997) stated that umbellulone (37.3%) was the main constituent, followed by -pinene (10.5%) and -muurolene (8.5%), of an oil extracted from Arizona cypress plants grown in Algeria.…”
