The UDP-glucuronosyltransferases (UGTs) have long been known to be inducible by various chemicals, including drugs, although the extent of induction in general has been modest. In the present study, we determined the ability of the dietary flavonoid chrysin to induce UGT activity, protein and mRNA. When pretreating human hepatoma Hep G2 cells with 25 microM chrysin, the glucuronidation of chrys...

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...

Chrysin is a bioactive flavonoid found in pollens, passion flowers, honey, royal jelly, and propolis, which commonly used as an ingredient natural food supplements primarily responsible for their pharmacological properties. A transparent chrysin-loaded microemulsion (CS-ME) prepared through ternary phase diagram was evaluated use antihyperalgesic formulation. It formulated with 40% Labrasol® (s...

Oxidative stress is known as the leading factor responsible for varicocele-related infertility and for that reason, many antioxidant therapies have been proposed. Considering that, we evaluated the reproductive outcomes and fertility of varicocelized rats and the impact of chrysin within these parameters. The animals were allocated into three groups: sham (control), varicocele treated via gavag...

Flavonoids is an intensively studied group of natural compounds with antioxidant, antineoplastic, antihyperglycemic, cardioprotective, and neuroprotective properties. The present study intends to investigate the geroprotective action of three selected flavonoids (naringin, luteolin, chrysin) in two model organisms, Caenorhabditis elegans and Drosophila melanogaster. Luteolin and chrysin were sh...

Propolis and its compounds have been the subject of many studies due to their antimicrobial and antiinflammatory activity; however, it is now known that they also possess antitumor properties. This review aims to summarize the results of studies on the mechanism of activity of propolis and its active compounds such as CAPE and chrysin in the apoptotic process, and their influence on the prolife...

Chrysin, a passion flower extract, may be beneficial because of its potential to attenuate surgical suppression of natural killer (NK) cell activity. We divided 37 male Sprague-Dawley rats into 3 treatment groups: (1) rats undergoing abdominal surgery and administered isoflurane and a 5% solution of dimethyl sulfoxide in saline (vehicle), (2) rats undergoing abdominal surgery and administered i...

Previously, we reported the role of synergy between two flavonoids-namely, chrysin and kaempferol-in inhibiting the secretion of a few major proinflammatory mediators such as tumor necrosis factor-alpha (TNF-α), prostaglandin E₂ (PGE₂), and nitric oxide (NO) from lipopolysaccharide (LPS)-induced RAW 264.7 cells. The present study aims to evaluate the effects of this combination on a murine mode...
