Abstract (EN): Coreopsis tinctoria Nutt., Asteraceae, fl owering tops infusion has been traditionally used in many countries to control hyperglycaemia. In this work we report for the fi rst time fatty acids and volatile compounds in this species. Fifteen fatty acids and sixteen volatile compounds were determined by GC-ITMS, being saturated fatty acids and monoterpenes the main compounds. The antioxidant and antibacterial potential of this matrix was checked for the fi rst time by several in vitro assays. A concentration-dependent activity was noticed against DPPH, nitric oxide and superoxide radicals. Antibacterial capacity was assessed against Gram-positive and Gram-negative bacteria, being more effective against the fi rst. Additionally, acetylcholinesterase and butyrylcholinesterase inhibitory activity was also evaluated, but no effect was found. Our results provide evidence of a wide diversity of compounds with several biological properties, improving the knowledge on this poorly studied matrix, which can lead to an increment of the use of C. tinctoria fl owering tops, namely in food and pharmaceutical applications.
