abstract = {Scolymus hispanicus L., also known as golden thistle, Spanish oyster thistle or, more commonly, as tagarnina is a plant that belongs to the Asteraceae family. It is collected from the wild for
human consumption in Mediterranean countries. It is a relevant ingredient in Andalusian culinary
culture, where the midribs of young plants are harvested for consumption. Scolymus hispanicus L.
contains a wide variety of phenolic compounds such as caffeoylquinic acids (CQAs), among others.
In the present work, the major phenolic compounds present in tagarnina have been identified, with
5-caffeoylquinic acid (5-CQA) and 3,5-dicaffeoylquinic acid (3,5-diCQA) being the main ones. A
method based on ultrasound-assisted extraction (UAE) has been developed for the extraction of
these compounds, with the percentage of methanol, sample-to-solvent ratio and the pH being the
most influential factors. The developed method has been validated and employed to determine the
concentration of 5-CQA and 3,5-diCQA in the midribs of Scolymus hispanicus, collected in six different
places in the south of Spain. The antioxidant activity of the samples has also been determined, and
a direct correlation with their caffeoylquinic compounds content has been established, showing an
antioxidant effect.},
