Phytochemical composition, and analgesic and antiinflammatory properties of essential oil of Chamaemelum nobile (Asteraceae L All) in rodents
Abstract
Purpose: To investigate the in vivo analgesic and anti-inflammatory activities of essential oil of dried flowers of Chamaemelum nobile (Asteraceae L. All) in Swiss mice and Wistar rats, respectively.
Methods: The volatile oil of the dried flowers of C. nobile obtained by hydrodistillation was analyzed by gas chromatography-mass spectrometry (GC-MS). Animals were assigned to the following experimental groups: C. nobile (180 mg/kg), ibuprofen (100 mg/kg) and vehicle-treated groups. Chemical and thermal pain models were used for the antinociceptive study in mice while fresh egg albumin-induced acute inflammation model in rats was used for anti-inflammatory study of the essential oil.
Results: The most abundant components of the oil were α-bisabolol (50 %) and farnesene (5.35 %). Oral administration of essential oil (180 mg/kg, po) significantly (p < 0.05) reduced pain and prevented inflammation in the different test models used in this study.
Conclusion: The essential oil of the dried flowers of C. nobile shows in vivo analgesic and antiinflammatory activities in rodents, and therefore, possesses potentials for development into effective analgesic and anti-inflammatory agent.
