    Abstract 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.

    Abstract 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.

    Abstract Phytochemical investigation of the roots of Atractylis serratuloides Sieber ex Cass. (Asteraceae) led to the isolation of nine compounds 1–9 including eight triterpenoids and one phenolic compound. Their structures were established on the basis of physical and spectroscopic analysis, including 1D and 2D NMR (1H, 13C, COSY, HSQC, and HMBC), mass spectrometry ESI, and by comparison with those published in the literature. Triterpenoids are typical compounds of Atractylis genus and could be useful as characteristic markers in chemotaxonomic research. In addition, isolated triterpenoids have previously showed many biological activities and might explain the use of A. serratuloides in traditional medicine.

    Abstract Three new bidesmosidic saponins (1–3), along with thirteen known metabolites consisting of two flavonoids and eleven triterpenoids were identified in dichloromethane and n-butanol extracts of the whole plant Atractylis flava Desf. The saponins were characterized as 3-O-[β-d-glucuronopyranosyl]-28-O-[β-d-xylopyranosyl-(1→4)-α-l-rhamnopyranosyl-(1→2)-β-d-xylopyranosyl]-16α-hydroxygypsogenic acid (1), 3-O-[β-d-glucuronopyranosyl]-28-O-[β-d-xylopyranosyl-(1→4)-α-l-rhamnopyranosyl-(1→2)-α-l-arabinopyranosyl]-16α-hydroxygypsogenic acid (2), and 3-O-[β-d-galactopyranosyl-(1→2)-β-d-glucuronopyranosyl]-28-O-[((3-O-acetyl)-β-d-xylopyranosyl)-(1→4)-((2-O-acetyl)-α-l-rhamnopyranosyl)-(1→2)-β-d-xylopyranosyl]-quillaic acid (3). Structures of all isolated compounds were elucidated by spectroscopic analysis, including 1D and 2D NMR (1H, 13C, COSY, HSQC, TOCSY, HSQC-TOCSY, HMBC, ROESY and NOESY), high-resolution electrospray ionization mass spectrometry (HRESIMS), acid hydrolysis, measurement of optical rotation and comparison with literature data.

    Abstract Two new flavonoid glycosides, together with twelve known compounds including seven flavonoids and five triterpenoids were isolated from the whole plant Atractylis flava Desf. The structures of new compounds have been elucidated as 6-hydroxykaempferol 6-methyl ether 7-O-β-glucopyranuronoside (1) and isorhamnetin 3-O-[(6″′-O-E-feruloyl)-β-d-glucopyranosyl-(1→2)]-β-d-galactopyranoside (2) named Atraflavoside A and B successively, on the basis of physical and spectroscopic analysis, including 1D and 2D NMR (¹H, ¹³C, COSY, TOCSY, HSQC, HMBC and NOESY) and mass spectrometry (HRESIMS) whereas those of the known compounds (3–14) were established by spectral comparison with those published in the literature.
