Strawberry pelargonidin glycosides are excreted in urine as intact glycosides and glucuronidated pelargonidin derivatives in rats

Hydroxylysine glycosides in human urine.

Hyd roxylysyl-galactosyl-glucose (HGG) and hyd roxylysyl-galactose (HG) were isolated from normal human urine and shown to be identical with hydroxylysine glycosides (OHLG’s) whose structure had been elucidated in other laboratories. We devised a procedure for separating the OHLG’s from many other urinary constituents by preliminary fractionation on a column of Sephadex. The OHLG’s in the fract...

Methyl glycosides are identified as glycosyl donors for the synthesis of glycosides, disaccharides and oligosaccharides.

Stable methyl glycosides are identified as glycosyl donors in the presence of AuBr(3) in acetonitrile; a panel of aglycones comprising aliphatic, alicyclic, steroidal and sugar alcohols are examined successfully for the glycosylation reaction and methyl glycosides of di- and tri- saccharides are converted to corresponding tri- and tetra-saccharides exploiting salient features of our novel activ...

Chronic Oral Pelargonidin Alleviates Learning and Memory Disturbances in Streptozotocin-Diabetic Rats

Diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the humans and experimental animals. Due to the anti-diabetic and antioxidant activity of pelargonidin (PG), this research study was conducted to evaluate the efficacy of chronic oral PG on alleviating learning and memory disturbance in streptozotocin-diabetic rats. Male Wistar rats were divided into...
