The herb Sideritis scardica is used in traditional medicine the Balkan Peninsula. Limited information exists on its health effects, such as improvement of cognitive functions. This study explores vitro anti-inflammatory effects extracts and polyphenols S. with focus neurodegenerative disease. BuOH, DCM EtOAc fractions were isolated from crude EtOH extract aerial parts further purified by chroma...

Free radical scavenging and cell aggregation inhibitory activities of 36 secondary metabolites isolated from the methanolic extracts of Verbascum cilicicum Boiss., V. lasianthum Boiss. ex Bentham, V pterocalycinum var. mutense Hub.-Mor., and V. salviifolium Boiss. (Scrophulariaceae) were investigated. The isolated compounds, 6-O-vaniloyl ajugol (1), ilwensisaponin A (2), ilwensisaponin C (3), v...

Transformed root cultures of Catalpa ovata were established following shoots infection with four agropine strains of Agrobacterium rhizogenes. Frequency of root formation was dependent on the bacterial strain and the presence of acetosyringone in the incubation medium. It is the first report concerning the possibility of transforming Catalpa ovata by A. rhizogenes. Both transformed and untransf...

This study aimed to determine biological activity and phytochemical study of Scutellaria platystegia (family Labiatae). Methanolic (MeOH) extract of aerial parts of S. platystegia and SPE fractions of methanolic extract (specially 20% and 40% methanolic fractions), growing in East-Azarbaijan province of Iran were found to have radical scavenging activity by DPPH (2, 2-diphenyl -1- pycryl hydraz...

From the roots of Myxopyrum smilacifolium Blume, five known compounds, verbascoside (1), arenarioside (2), myxopyroside (3), 3-formylindole (4), and 5-hydroxymethyl furfural (5) were isolated. Their chemical structures determined by ESI-MS, 1D, 2D-NMR spectrascopic data analysis as well in comparison with those reported literatures.

In farm animals, oxidative stress can be involved in several intestinal pathological disorders, and many antioxidant molecules, especially those of plant origin, can counteract free radicals, thus stabilizing the gut environment and enhancing health. The aim of the study was to investigate whether the use of verbascoside (VB), a polyphenol plant compound, in pig feeding could modulate oxidative...

BACKGROUND The phytochemical analysis of Stachys alopecuros subsp. divulsa, an endemic Italian species, has been recently reported and has showed the presence of 8-O-acetylharpagide (2), harpagide (3), allobetonicoside (4), and 4¢-O-galactopyranosyl-teuhircoside (5). In this paper, an in deep study of its glycosidic fraction with the aim to widen the knowledge on its secondary metabolites conte...
