About this deal
In the aforementioned study in the Netherlands in 1988, most of the average daily intake was attributed to quercetin, about 16 mg/day, and the actual daily intake of apigenin was only about 0.
The flavonoid apigenin inhibits hepatitis C virus replication by decreasing mature microRNA122 levels,” Virology, vol. However, as consumers intentionally increase apigenin intake from dietary supplements or pharmaceutical sources, safety concerns may arise with a higher level of apigenin exposure. Zhang, “Studies of the in Vitro Antibacterial Activities of Several Polyphenols against Clinical Isolates of Methicillin-Resistant Staphylococcus aureus,” Molecules, vol. One study on rats concluded that apigenin has a slow absorption because after a single oral administration of radiolabeled apigenin, radioactivity appeared in the blood 24 hours later [ 59]. N. Eloff, “Biological activity of five antibacterial flavonoids from Combretum erythrophyllum (Combretaceae),” Journal of Ethnopharmacology, vol.
aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa, especially 7-[3-(Morpholin-4-yl)propoxy]-5-hydroxy-2-(4-hydroxyphenyl)-4H-chromen-4-one [ 99]. Hiramatsu, “Apigenin as an anti-quinolone-resistance antibiotic,” International Journal of Antimicrobial Agents, vol. The EC 50 value, inhibitory concentration of compound that produces 50% inhibition of virus-induced cytopathic effects, for apigenin to block EV71 infection was 11.
Yano S, Umeda D, Yamashita T, Ninomiya Y, Sumida M, Fujimura Y, Yamada K, Tachibana H Dietary flavones suppresses IgE and Th2 cytokines in OVA-immunized BALB/c mice. It is hypothesized that apigenin glucosides can be hydrolyzed into apigenin by cytosolic β-glucosidase (CBG) and lactase-phlorizin hydrolase (LPH), which are enzymes produced by the liver or intestinal cells, or the gut microbiota [ 4, 71, 72]. Apigenin was the most potent inhibitor of transcriptional activation of both inducible cyclooxygenase (COX-2) and inducible nitric oxide synthase (iNOS) in lipopolysaccharide (LPS)-activated RAW 264. Broth microdilution and agar dilution are the most popular methods to determine the minimal inhibitory concentrations; however, due to system differences, there are discrepancies between the values obtained from the two methods. Simultaneous determination of five flavonoids from Scutellaria Barbata extract in rat plasma by LC-MS/MS and its application to pharmacokinetic study,” Journal of Chromatography B, vol.Merfort I, Heilmann J, Hagedorn-Leweke U, Lippold BC In vivo skin penetration studies of camomile flavones. pylori-induced histological changes of neutrophil and monocyte infiltrations and atrophic gastritis [ 113].
