This study will trace the path of a natural plant pigment, (cyanidin-3-glucoside; C3G), through the human body after consumption. C3G is the most abundant of the naturally occurring anthocyanin family of plant pigments and is responsible for the red to purple colour of many fruits and vegetables. Anthocyanins are promoted as being potentially beneficial to heart-health and also have anti-cancer properties, however little is known about how the body processes these compounds after they are eaten or how they are cleared from the digestive system. The investigators study aims to answer these questions and, in doing so, unravel how they may benefit everyone's health.
In this BBSRC funded study, 8 healthy (18-45y) male participants will be recruited to a one day feeding study (lasting 8 hours) to establish the routes of clearance of anthocyanins from the body. After consent has been obtained, participants will be screened to establish their health (by NHS clinical staff). Eligible participants will be asked to consume a low anthocyanin diet for 7 days and to attend a study day at the Clinical Research & Trials Unit (CRTU, University of East Anglia). Participants will attend in a fasted state (at least 8h of water only) and will be asked to provide a urine (total morning void) and faecal (within the previous 72h) sample. Participants will then consume a C3G capsule and blood and breath samples will be collected at regular intervals after consumption (0.5, 1, 2, 4 and 6 hours). The capsule is roughly the size of a commercial vitamin-C tablet (500mg). Participants will then return in a fasted state on the following 2 mornings to provide further urine, faeces, breath and blood samples. Low anthocyanin meals will be provided throughout the study day and on the following 2 mornings. Participants will be reimbursed for their inconvenience

The aim of the present study is to describe the bioavailability for the proprietary standardized maqui berry extracts Delphinol® and MaquiBright® enriched in anthocyanins and in particul...
The primary objectives of this study are to identify positivity rates to three novel surfactants (ingredients used in soaps, detergents, and other cleansers that serve to lower the surface...
The purpose of this research study is to test the ability of Mucinex, an oral, over-the-counter, FDA approved expectorant) to stimulate the clearance of inhaled particles from the subject'...
Compared to early postpartum (10-15 weeks) observations, paracetamol clearance was significantly higher (21.1 vs 11.7 l.h-1, + 80 %) at delivery. This higher clearance was due to a disprop...
The goal of this study is to define 25(OH)D3 catabolism in CF patients using gold standard pharmacokinetics studies. Specifically, the investigators will evaluate the metabolic clearance o...
The purpose of this in vitro study was to evaluate the efficacy of erythrosine and cyanidin-3-glucoside as photosensitizers in PDT for the elimination of Porphyromonas gingivalis (P. gingivalis) biofi...
Phytoestrogens are plant compounds with estrogenic effects found in many foods. We have previously reported phytoestrogen activity of blackcurrant anthocyanins (cyanidin-3-glucoside, cyanidin-3-rutino...
Purple sweet potato was fermented into alcoholic beverage. By using LC-MS analysis, 12 types of anthocyanins were found in the purple sweet potato alcoholic beverage (PSPFAB); these were based on cyan...
In this study, chemical chaperone like function of cyanidin-3-O-glucoside (C3G) was investigated through fluorescence spectroscopy, UV-visible spectroscopy, circular dichroism spectroscopy, confocal m...
Zearalenone (ZEN) and its phase II sulfate and glucoside metabolites have been detected in food and feed commodities. After consumption, the conjugates can be hydrolyzed by the human intestinal microb...
A group of FLAVONOIDS derived from FLAVONOLS, which lack the ketone oxygen at the 4-position. They are glycosylated versions of cyanidin, pelargonidin or delphinidin. The conjugated bonds result in blue, red, and purple colors in flowers of plants.
A plant genus of the family LAMIACEAE that contains isoscutellarein-7-O-(allosyl(1-2)glucoside).
A subclass of iridoid compounds that include a glucoside moiety, usually found at the C-1 position.
A plant genus of the family Cycadaceae, order Cycadales, class Cycadopsida, division CYCADOPHYTA of palm-like trees. It is a source of CYCASIN, the beta-D-glucoside of methylazoxymethanol.
A glucoside-derived SODIUM-GLUCOSE TRANSPORTER 2 inhibitor that stimulates urinary excretion of glucose by suppressing renal glucose reabsorption. It is used to manage BLOOD GLUCOSE levels in patients with TYPE 2 DIABETES.
