dc.description.abstractMedicinal plants are known as being a rich source of bioactive components, which can be correlated with their biological effects. The present study focused on the valorization of the leaves of Osyris quadripartite Salzm. ex Decne. with recognized folk medicinal uses in some Africa countries, namely Algeria [1, 2]. Therefore, the aim was to perform a phytochemical characterization, regarding phenolic composition, of O. quadripartita aqueous extracts and two different organic fractions (n-butanol and ethyl acetate), by using high-performance liquid chromatography coupled to a diode array detection and electrospray ionisation mass spectrometry (HPLC-DAD–ESI/MS). The separation was achieved with a Waters Spherisorb S3 ODS-2 C18 (4.6 mm × 150 mm, 3 μm), using a gradient elution, with 0.1% formic acid in water and acetonitrile. Twenty-eight individual phenolic compounds were identified: fifteen flavan-3-ols, six flavones, four flavonols, two phenolic acids and one flavanone derivative. The ethyl acetate fraction presented the highest concentration in phenolic compounds, being (+)-catechin and procyanidin dimer B1 (EC-4,8-C) the most abundant compounds (110.5 ± 0.3 and 100.5 ± 0.3 mg/g extract, respectively). The aqueous extract and the n-butanol fraction presented similar contents of phenolic compounds, being quercetin-3-O-rutinoside the main molecule present (33.8 ± 0.1 and 17.70 ± 0.02 mg/g extract, respectively). Moreover, the phenolic profiles of all fractions and extracts presented similarities in their qualitative composition, although some differences were observed, especially in the ethyl acetate fraction, where no flavone derivatives were present. This study highlights the potential of O. quadripartita fractions, rich in phenolic compounds, to be used in food, pharmaceutical and cosmetic fields.pt_PT
