In this study, I determined the essential oil (EO) chemical composition and crude methanol extract (ME) phytochemical profile of the leaves of Acacia gerrardii (ACGL), a plant growing in Saudi Arabia. Additionally, I assessed their in vitro antioxidant activity. The gas chromatography‐mass spectrometry analysis of the EO revealed a high content of oxygenated monoterpenes (79.86 %), primarily dominated by pulegone (35.11 %), carvacrol (27.36 %), and neo‐dihydrocarveol (4.67 %). The ME was analyzed by liquid chromatography‐mass spectrometry to determine its qualitative chemical profile. Four organic acids, eleven phenolic compounds, sixteen flavonoids, nine terpenoids (eight triterpenoids and one diterpenoid), and one coumarin were found in the ME of ACGL. This extract was found to be dominated by 5,6,4‐trihydroxy‐7,3‐dimethoxyflavone (39.30 %), acteoside (30.27 %), nevadensin (7.55 %), isoacteoside (3.08 %) and apiin (3.23 %), and hesperidin (2.73 %). The phenolic (TPC=127.70±1.47 mg gallic acid equivalents/g of extract) and flavonoid (TFC=85.48±0.12 mg quercetin equivalents/g of extract) contents of the ME were also assessed. The in vitro antioxidant activities of both the EO and ME were evaluated using DPPH, ABTS, and ferrous ion chelating effect assays. Compared to the positive control (vit. E and Vit. C), and both extracts exhibited excellent activity.

The inhibitory impact of the methanolic Ajuga orientalis (MAO) extract on Al corrosion in 1.0 M NaOH solution was examined using weight loss with electrochemical polarisation and scanning electron microscopy (SEM) techniques. According to the findings, the extract was an effective inhibitor in basic condition, as well as inhibition effectiveness increased with concentration. Furthermore, temperature studies revealed a loss in efficiency followed by a rise when temperature rose, followed by an increase and a fall in the fundamental media when the temperature increased from 30 °C to 50 °C. Frumkin, Freundlich and El Awady isotherms were used to mimic the inhibitor's adsorption properties. For the inhibitory behaviour, physical and chemical adsorption mechanisms are proposed. The adsorption process's thermodynamic parameters (ΔH*, ΔS* and Ea) were determined and explained. The inhibitor was examined as a mixed-type (anodic and cathodic) inhibitor based on polarisation studies. The inhibitor, according to the SEM data, is partially coating the metal surface, providing it with a reasonable amount of protection. The findings from weight loss, electrochemical polarisation, SEM and quantum chemical calculations collectively demonstrate a strong consensus, indicating that the MAO extract exhibits high effectiveness as an inhibitor for aluminium in a basic solution.
