Chemical Composition, Antifungal and Herbicidal Effects of Essential Oil Isolated from Chersodoma argentina (Asteraceae)

Analysis of the hydrodistilled essential oil of the aerial parts of Chersodoma argentina Cabrera by GC- MS and NMR spectroscopy revealed that over 80% consisted of monoterpene hydrocarbons such as α-thujene, α-pinene and β-pinene. Contact and headspace volatile exposure assays of the essential oil d...

Zusammenfassung:Analysis of the hydrodistilled essential oil of the aerial parts of Chersodoma argentina Cabrera by GC- MS and NMR spectroscopy revealed that over 80% consisted of monoterpene hydrocarbons such as α-thujene, α-pinene and β-pinene. Contact and headspace volatile exposure assays of the essential oil demonstrated antifungal activity against Sclerotinia sclerotiorum, Sclerotium rolfsii and Rhizoctonia solani with the contact assay showing greater activity than the headspace assay. Herbicidal activity was shown by reduced root growth of Allium porrum, Solanum lycopersicon and Sorghum halepense in both assays.
