ANALYSIS OF THE BIOACTIVITY, METABOLISM, AND PHARMACOKINETICS OF ANTHOCYANINS IN HUMANS Colin Kay Advisors: University of Guelph, 2004 Professor B. J. Holub Professor G. Mazza Recent interest in the health-promoting properties of berry anthocyanins has been based on studies reporting their significant in vitro antioxidant activities. However, information regarding the bioavailability, metabolis...

The effect of fermentation, storage and stewing on the content and composition of anthocyanins as well as antioxidant capacity of red cabbage was studied. The observation of anthocyanins profile by HPLC-DAD-MS/MS was conducted. Red cabbage products contained twenty different nonacylated and acylated anthocyanins with main structure of cyanidin-3-diglucoside-5-glucoside. Treatments applied affec...

This article presents a review about anthocyanins and shows they have anticancer property. Mechanism that may be responsible for the inhibitory effect of anthocyanins in carcinogenesis and tumor growth is either cellular redox status modification or any interference with basic cellular functions like cell cycle, apoptosis, inflammation, angiogenesis, invasion and metastasis. New anticancer agen...

Total anthocyanins in different cultivars of mulberry were measured and a process for the industrial preparation of mulberry anthocyanins as a natural food colorant was studied. In 31 cultivars of mulberry, the total anthocyanins, calculated as cyanidin 3-glucoside, ranged from $147.68$ to $2725.46$ mg/L juice. Extracting and purifying with macroporous resins was found to be an efficient potent...

Anthocyanins were extracted from a mixture of berries of Vaccinium angustifolium and Vaccinium myrtilloïdes at 7.7 degrees C, 26 degrees C, and 79 degrees C using ethanol alone or ethanol acidified with hydrochloric, citric, tartaric, lactic, or phosphoric acids at a solvent to solid ratio of 10. The effect of these parameters on extracted anthocyanins stability was investigated. The pH-differe...

The current status of research on anthocyanins, their biological effects in vitro and in vivo and their potential application in human therapy are reviewed. Anthocyanins are a class of compounds belonging to the larger flavonoids class which comprises a subset of the polyphenol class of compounds. Anthocyanins are almost exclusively found in higher plants. Major sources of anthocyanins are blue...

Cranberry, which is rich in polyphenols, including anthocyanins and proanthocyanidins, has been found to have various effects beneficial to human health, including prevention of urinary tract infections. These effects have been associated with polyphenols in the fruit. We investigated the excretion of anthocyanins in human urine after ingestion of cranberry juice. Eleven healthy volunteers cons...

This paper compares two medicinal species of Kalanchoe, which are often used interchangeably by the population, regarding the distribution of anthocyanins under the influence of four luminosity levels for 6 months. For the morphoanatomical analysis, the 6th stem node of each plant was sectioned. Usual histochemical tests revealed the presence of anthocyanins by cross sections of the stems, peti...

Anthocyanins are colored water-soluble pigments belonging to the phenolic group. The pigments are in glycosylated forms. Anthocyanins responsible for the colors, red, purple, and blue, are in fruits and vegetables. Berries, currants, grapes, and some tropical fruits have high anthocyanins content. Red to purplish blue-colored leafy vegetables, grains, roots, and tubers are the edible vegetables...
