“…This chemical composition differed significantly from the results obtained by Boti et al [28], showing that the major component of the root-bark oil of C. sumatrensis from Cô te dIvoire was (Z)lachnophyllum acid methyl ester (75.0%). Only 42 components were identified in the root oil, with 4 as the dominating compound (74.3%).…”

“…sumatrensis and C. sumatrensis var. Boti et al [28] showed that the leaf and flower oils of C. sumatrensis from Cameroon exhibited broad antifungal activities. The volatile constituents and antifungal activity of the essential oils of C. sumatrensis have been previously investigated [37].…”

“…The major component was also compound 1 (24.9%). Moreover, several studies in Cô te dIvoire [28] have shown that the leaf and flower oils of C. sumatrensis were dominated by compounds 3 (13.0 -25.5%), 8 (7.8 -17.5%), and 7 (9.1 -15.8%) and germacrene D (3.6 -13.6%). The essential oil of the same species growing in Cameroon contained mainly compounds 8 (22.3 -21.1%), 7 (17.3 -20.1%), and germacrene D (10.1 -11.0%) [37].…”

Conyza sumatrensis (Retz.) E.WALKER (Asteraceae) is a spontaneous annual herb, fairly widespread throughout Tunisia, which has rarely been studied or valued in any sector. Essential oils were obtained by hydrodistillation of different parts (flower heads, leaves, stems, and roots) of C. sumatrensis plants, which were collected in autumn (November 2007) at the flowering stage in the area of Monastir, Tunisia. In total, 98 compounds, representing 88.1-99.3% of the oil composition, were identified by GC-FID and GC/MS analyses. The root essential oil was distinguished by its high content in acetylenes (matricaria ester, 4; 74.3%), while those from flower heads and leaves were dominated by oxygenated sesquiterpenes (61.1 and 50.3%, resp.). The oils of C. sumatrensis from Tunisia belonged to a matricaria ester/caryophyllene oxide chemotype. All the oils were evaluated for antibacterial, antifungal, and allelopathic activities. The results indicate that the leaf oil exhibited significant in vitro antibacterial activity against Enterococcus faecalis, Staphylococcus aureus, and Proteus mirabilis and that the C. sumatrensis oils isolated from the aerial parts presented high mycelia-growth inhibition of Candida albicans and the filamentous fungi tested. Moreover, the essential oils of the different plant parts inhibited the shoot and root growth of Raphanus sativus (radish) seedlings. Indeed, the inhibition of the hypocotyl growth varied from 28.6 to 90.1% and that of the radicle from 42.3 to 96.2%.

“…To our knowledge, no phytochemical investigations on X. rubescens have been undertaken to date. In continuation of our ongoing work on the characterization of aromatic and medicinal plants from the Ivory Coast through the chemical composition of their essential oils, the aim of the present work was to investigate the chemical composition of X. rubescens leaf oil. The structures of three new compounds have been elucidated and one component has been reported for the first time as a natural compound.…”

Phytochemicals have been isolated from extracts of various Xylopia species (Annonaceae) growing wild in the African rainforest. In contrast, no phytochemical investigations have been reported to date on Xylopia rubescens Oliv. The aim of the present work was to describe the composition of X. rubescens leaf oil. Analysis of the leaf oil has been undertaken by a combination of chromatographic and spectroscopic techniques. Three new compounds have been isolated and their structures elucidated as furanoguaia‐1,4‐diene, furanoguaia‐1,3‐diene and (8Z,11Z,14Z)‐8,11,14‐heptadecatrien‐2‐ol. One other compound is reported for the first time as a natural compound. The oil composition was dominated by both furanoguaiadienes (34.2% and 11.4%, respectively) and by (8Z,11Z,14Z)‐8,11,14‐heptadecatrien‐2‐one (12.8%). The composition of X. rubescens leaf oil varied dramatically from those of the essential oils isolated from other Xylopia species. Copyright © 2013 John Wiley & Sons, Ltd.
