Brocchia cinerea (Vis.) is an Asteraceae-family plant widely used in traditional medicine in Southeastern Morocco to treat several ailments. The aqueous extracts of flowers, leaves, stems and aerial parts of B. cinerea were subjected to a preliminary phytochemical screening test for various constituents. The polyphenols, flavonoids, and tannins contents were determined. Moreover, the antioxidant activity was evaluated by DPPH scavenging assay and ferric reduction antioxidant power. However, the antibacterial activity was evaluated against six pathogenic bacteria. Phytochemical screening of different parts of B. cinerea revealed alkaloids, flavonoids, saponins, tannins, and terpenoids. The leaves extract showed the highest polyphenols concentration (27.15±0.92 mg GAE/g of Ext) and flavonoids (17.46±0.66 mg QE/g of Ext), while flowers extract was highest in tannin (9.57±1.24 mg TAE/g of Extract). All extracts of B. cinerea showed moderate to high antioxidant power, among which the leaves extract demonstrated the strongest antioxidant activity, with an IC50 value of 0.99 mg/mL and an optical density of 1.15. In the case of antibacterial activity screening, leaves extract showed the highest inhibition zone diameters ranging from 9 to 27 mm against the tested bacteria. The results demonstrate that the aqueous extracts of different parts of B. cinerea, especially the leaves, could be developed as pharmaceutical products.

Taxus species in different parts of the world prevent the formation of hepatoprotective, anticoagulant, antiulcerogenic, anti-coagulant, antifungal and tumour cells. In this study, biological activity studies were performed on the leaves, branches and fruits of the methanol extract of Taxus baccata L. species collected from Sivaslı district of Uşak province. The methanol extract of the T.baccata species, the total amount of phenolic content of the sample was found to be 14.76 mg GAEQ/1g dry sample in the highest leaves. In T.baccata methanol extract, the maximum amount of flavonoid content was 0.468±mg QE/g dry sample. Antioxidant activity value as DPPH radical; % inhibition value was found as 93.21%. Based on the results; It can be concluded that the leaves of T.baccata have higher antioxidant activity than fruits and branches. Future studies need to explore the chemical components contained in the T.baccata species to determine and investigate in further detail.
