The complex formation between Cr(III) and morin was carried out in methanol and confirmed by analytical characterization using UV-Vis, IR, (1)H NMR, and TG-DTA. UV-Vis shows significant bathochromic shift in benzoyl upon coordination as well as IR well illustrates the peak shift of C=O group and formation of a O-Cr(III) bond. Likewise, (1)H NMR studies clarify that Cr(III) metal ion replaces th...

UNLABELLED BACKGROUND Plant flavonoids are emerging as potent therapeutic drugs effective against a wide range of aging diseases particularly bone metabolic disorders. Morin (3,5,7,20,40-pentahydroxyflavone), a member of flavonols, is an important bioactive compound by interacting with nucleic acids, enzymes and protein. The present study was designed to investigate the putative beneficial e...

The present study deals with the synthesis, characterization of zinc-morin complex and evaluation of its antidiabetic efficacy in High Fat Diet (HFD)-fedStreptozotocin (STZ) induced diabetic rats. Oral administration of zinc-morin complex to diabetic rats (5mg/kg body weight/day) for a period of 30 days resulted in the decreased levels of blood glucose and HbA1c. Oral administrations of the zin...

Considering drug-induced lipid peroxidation as a possible mediator of drug-induced toxicity and exploiting the free radical scavenging action of antioxidants, the present study was designed to evaluate the antiperoxidative potential of morin on cyclophosphamide/flutamide-induced lipid peroxidation and also to evaluate the effect of morin on cyclophosphamide/flutamide-induced changes in choleste...

This study investigated the effect of morin on membrane bound enzymes and glycoproteins in normal and streptozotocin (STZ)-induced diabetic Wistar rats. Diabetes was induced in rats by an intraperitoneal injection of STZ, dissolved in citrate buffer (0.01 M, pH 4.5) and injected to overnight fasted rats with a dose of STZ 50 mg/kg. Morin was dissolved in carboxy methyl cellulose (CMC) at a dose...

The antibacterial activities of flavonoids were found by the paper disk method to be enhanced by combining or mixing them. The combinations of quercetin and quercitrin, quercetin and morin, and quercetin and rutin were much more active than either flavonoid alone. Although rutin did not show activity in itself, the antibacterial activities of quercetin and morin were enhanced in the presence of...

Selective UV-spectrophotometric methods for determination of iron(III) in iron(II) samples have been developed. The methods are based on the interaction of Fe(III) with quercetin and morin, compounds of the flavonoid group. Redox reactions occurring between Fe(III) ions and the reagents used make the basis for the detection. Iron(II) does not react with quercetin and morin under the conditions ...

The potential capabilities and analytical performance of lab-on-valve (LOV) manifold as a front end to amperometry have been explored for the on-line determination of morin. Meanwhile, the electrochemical behaviors of morin were investigated based on polyvinylpyrrolidone- (PVP-) doped carbon paste electrode (CPE), which found that PVP can significantly improve its oxidation peak current. The ex...

Morin (2´,3, 4´,5,7-pentahydroxyflavone) is a flavonoid with several beneficial health effects. However, its poor water solubility and it sensitivity to several environmental factors avoid its use in applications like pharmaceutical and cosmetic. In this work, we synthetized morin-modified mesoporous silica nanoparticles (AMSNPs-MOR) as useful material to be used as potential nanoantioxidant. T...

1246 NOTICES OF THE AMS VOLUME 49, NUMBER 10 A visitor to the Paris apartment of the blind geometer Bernard Morin finds much to see. On the wall in the hallway is a poster showing a computergenerated picture, created by Morin’s student François Apéry, of Boy’s surface, an immersion of the projective plane in three dimensions. The surface plays a role in Morin’s most famous work, his visualizati...
