Abstract
Objective: To determine the chemical compositions of essential oil from the aerial parts of Equisetum ramosissimum (E. ramosissimum).
Methods: The essential oil from the aerial parts of E. ramosissimum was detected using gas chromatography -mass spectrometry (GC-MS).
Results: Chemical analyses detected thirty seven compounds.
Conclusions: α-bisabolol Oxide A (12.3%) and cuminaldehyde (9.8%) were identified as major constituents of the oil. Moreover, the presence of carvacrol was unusual as compared to other Equisetum spp. Given the ovicidal effect of carvacrol on neonate larva, further investigations are urged to question the toxicological effect of the essential oil of E. ramosissimum on reproductive health in animals.
Keywords: Equisetum ramosissimum, essential oil, hydrodistillation, GC-MS
