Ridolfia segetum Moris, commonly known as corn parsley, false fennel , or false caraway , is distributed throughout the Mediterranean region. It belongs to the Apiaceae (carrot or parsley family), that includes well-known aromatic and medicinal plants with characteristic hollow stems. R. segetum is used in traditional medicine to prevent constipation, coughing and respiratory tract infections. The present work aimed to characterize the chemical composition of the essential oil obtained from the flowering aerial parts of R. segetum collected in Portugal, as well as to evaluate the anti-inflammatory activity at concentrations safe to mammalian cells. The oils were characterized by GC and GC-MS. Assessment of cell viability was made by the MTT assay and the in vitro anti-inflammatory potential of the oil was evaluated by measuring NO production using LPS-stimulated mouse macrophages as in vitro inflammatory model. The main compounds of the oils are α-phellandrene (63.3%) and terpinolene (11.9%). The oil significantly inhibited NO production (0.16 μL/mL) without affecting cell viability, at concentrations up to 1.25 μL/mL. These findings add significant information to the pharmacological activity of Ridolfia segetum essential oils, specifically to its anti-inflammatory properties, thus justifying and reinforcing its use in traditional medicine. Taken together, these results provide evidence of the therapeutical effects of this oil, and suggest that the anti-inflammatory activity in doses without cytotoxicity, combined with its pleasant odor could be of great value to cosmetic and pharmaceutical industries. Additional studies are ongoing in our lab to clarify the cellular and molecular mechanisms underlying these properties.
