Screening of flavonoid compounds in fruit, leaf, stem and root bark extracts of Z. leprieurii was achieved by liquid chromatography (LC) coupled with tandem mass spectrometry (MS2). Among the 186 reference compounds tested, four flavonoids were identified in one or other of the organ extracts from each plant (fruit, leaf, root barks and stem): neodiosmin and hesperidin were identified in all extracts. The presence of datiscin was reported only in leaves while that of rutin was identified in fruits and leaves. Of these four flavonoids, three (neodiosmin, datiscin and rutin) are detected for the first time in Z. leprieurii. The antioxidant properties of different extracts were tested regarding their scavenging activities on ABTS•+ radical. Fruit, leaf and stem extracts had low antioxidant potential and root bark extracts exhibited very low antioxidant activity. Keywords: Zanthoxylum leprieurii, flavonoids, LC-MS/MS and antioxidant activity.
