The main sources of polyphenols are medicinal herbs, vegetables and fruits. Numerous analytical
procedures have been developed for the quantification of phenolic compounds in herbs. High
performance liquid chromatography method coupled with mass spectrometry (LC–MS) is one of the
most used techniques.
This work aimed to ascertain the phenolic compounds of ethyl acetate extract of Centaurea
papposa, in order to find new sources of polyphenols.
Phenolic compounds were appraised using LC-MS technique, à l'aide d'une UHPLC Shimadzu de
modèle Nexera couplée à un instrument MS en tandem.
LC-MS analysis revealed the presence of 21 compounds among which 13 were phenolic acids, 6
flavonoids, 1 phenolic aldehyde and 1 benzo-pyrone.
The results show that ethyl acetate extract of Centaurea papposa can be used as a herbal drug, In
view of the beneficial effects on health identified for phenolic compounds
