Five flavonoid glycosides and two derivatives were isolated from the herbs of Scorzonera austriaca Wild by silica gel column chromatography and preparative HPLC. Their structures were identified, using chemical and spectroscopic methods, as 5,7,4'-trihydroxyflavone 6-C-(2''-O-β-d-glucopyranosyl β-d-glucopyranoside) (1), 5,7,3',4'-tetrahydroxyflavone 6-C-(2''-O-β-d-glucopyranosyl β-d-glucopyrano...

Defect in apoptosis has been implicated as a major cause of resistance to chemotherapy observed in B cell chronic lymphocytic leukaemia (B CLL). This study evaluated the pro-apoptotic effect of an anthocyanin-rich dietary bilberry extract (Antho 50) on B CLL cells from 30 patients and on peripheral blood mononuclear cells (PBMCs) from healthy subjects, and determined the underlying mechanism. A...

Introduction Reactive oxygen species (ROS) have been shown to play a critical role in many diseases such as diabetes mellitus, cancer, Alzheimer, arteriosclerosis and other conditions. Chronic glucose levels in blood or cells of diabetic patients are known to cause oxidative damages, followed by an increasing in ROS production and/or dysfunction of antioxidant defense system (enzyme or non-enzy...

A novel β-lactam derivative, albactam, was isolated from the alcoholic extract of the flowers of Albizia lebbeck. It showed a significant anti-aggregatory activity against adenosine diphosphate and arachidonic acid induced guinea-pigs' platelets aggregation in vitro. Six more known compounds were also isolated and fully characterized by measuring 1D and 2D NMR, two of them are the triterpenes β...

Seven flavonoids have been isolated from the aerial parts of Halostachys caspica C. A. Mey. (Chenopodiaceae) for the first time. By means of physicochemical and spectrometric analysis, they were identified as luteolin (1), chrysin (2), chrysin 7-O-β-D-glucopyranoside (3), quercetin (4), quercetin 3-O-β-D-glucopyranoside (5), isorhamentin-3-O-β-D-glucopyranoside (6), and isorhamentin-3-O-β-D-rut...

Methanol 70% extract of Bauhinia racemosa aerial parts was tested for antimicrobial activity against different bacterial and fungal strains and for antioxidant activity and also total content of polyphenols with phytochemical analysis of the extract was determined. The results have showed that the extract has a significant antimicrobial activity, it inhibited the growth of Bacillus subtilis and...

A bioactivity-guided fractionation of the ethyl acetate fraction of the flowers of Onopordum alexandrinum L. (Asteraceae) yielded a new flavonoidal glycoside designated as acacetin-7-O-galacturonide (9), alongside with nine known flavonoids; 6-methoxy-apigenin (hispidulin) (1), acacetin (2), apigenin (3), luteolin (4), kaempferol (5), eriodictyol (6), apigenin-7-O-glucoside (7), luteolin-7-O-gl...

A set of 54 snap bean lines grown under organic farming was characterized for different traits: pod color, cross-section shape, section width (PSW), protein content (PC), and sugar (S). After cooking, the were analyzed firmness color parameters (CIE-L*, a*, b*). The grouped based on shape into eight groups, significant differences observed among groups all traits investigated. In particular, ye...
