Can Cranberry Supplementation Reduce Risks For Diabetes?, Belinda K. Chambers

Electronic Theses and Dissertations

Diabetes affects approximately 250 million people worldwide and health care costs related to diabetes equal approximately $98 billion each year. Aldose reductase has been shown to contribute to the side effects of diabetes including kidney disease, nerve disease, and retinopathy. Cranberries contain anthocyanins and other flavonoids that have been shown in vitro to inhibit the enzyme aldose reductase and to inhibit protein glycosylation. It is believed that daily cranberry supplementation could reduce side effects of diabetes. Twenty-seven adults with type 2 diabetes were recruited for this 12 week double-blind, placebo-controlled study. Fasting blood analysis was done at weeks 0, 6 ...

Chemical Characterization Of Wild Maine Cranberries, Dolly Jean Watson

Electronic Theses and Dissertations

This study was conducted to analyze wild Maine cranberries for anthocyanin (ACY), anthocyanidin, organic acid, L-ascorbic acid, and moisture content. Cranberries were analyzed in both the fiesh and fiozen states. Analysis for ACY and anthocyanidin content was performed by High Performance Liquid Chromatography (HPLC) and Capillary Electrophoresis (CE); organic acids by HPLC; and L-ascorbic acid (L-AA) and moisture by AOAC methods for titration and drying, respectively. ACY results showed similar qualitative profiles for all cultivars except one where no detectable ACY were present. Four major peaks and two minor peaks were detected, which have been tentatively identified as the galactosides ...
