    The phytochemical study of the 70% ethanol extract of the aerial parts of Diplotaxis erucoides afforded one new flavonoid glycoside, namely kaempferol-3-O-[α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranoside]-7-O-α-L-rhamnopyranoside (1), named diploerucoside A and seven known compounds including one flavonoid (2), one phenolic glycoside (3), one monoterpene (4), one triterpene (5), one sitosterol (6) and two monoglycerolipids (7, 8). Their structures were established by extensive spectroscopic analysis including 1 D- and 2 D-NMR (1H, 13C, 1H-1H COSY, HSQC and HMBC), mass spectrometry (HR-ESI-MS) and by comparison with the data reported in the literature.

    Phytochemicals, Antihemolytic, Anti-inflammatory, Antioxidant, and Antibacterial Activities from Thymus Algeriensis
    (TAYLOR & FRANCIS LTD, 2021-03-12) Mokhtari, Mouna; Chabani, Sonia; Mouffouk, Soumia; Aberkane, Mohamed-Cherif; Dibi, Ammar; Benkhaled, Mohammed; Haba, Hamada
    The chemical composition and anti-inflammatory, antihemolytic, antioxidant, and antibacterial activities of solvent extracts of Thymus algeriensis in petroleum ether, chloroform, and n-butanol were evaluated. Ten compounds including four flavonoids, four phenolics, and two triterpenoids were isolated and identified by chromatography and spectroscopy. The n-butanol extract had the greatest antioxidant activity and inhibited hemolysis with a value of IC50 at 322.85 ± 0.87 µg mL−1. The chloroform extract exhibited the highest anti-inflammatory effect with 45.27% inhibition. The extracts demonstrated antibacterial activity against the tested strains.
