Exploration of Potential Biomarkers of Polyphenol Intake From a Supplement Derived From Artichoke By-products Rich in Hydroxycinnamic Acids (ARTI-UP ADME) (ARTI-UP ADME)
Exploration of Potential Biomarkers of Polyphenol Intake From a Supplement Derived From Artichoke By-products Rich in Hydroxycinnamic Acids
The bioavailability study analyzes the absorption, distribution, metabolism, and excretion (ADME) processes of the polyphenols under study (HCAs). To achieve the planned objectives, blood and urine samples will be collected before and at different time intervals following the intake of the study supplement, which will consist of capsules made from dehydrated artichoke by-products rich in HCAs.
To determine the bioavailability of the active compounds, volunteers will be asked to follow a diet low in polyphenols/plant-based foods for 48 hours prior to the supplement intake and up to 48 hours after product consumption . Blood and urine samples will be collected before intake and during the following 48 hours. Subsequently, the samples will be analyzed using high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS) to identify and quantify the bioactive compounds of interest and their metabolites. The results of the ADME trial will allow for the identification of plasma and urinary metabolites, the characterization of intake markers, and the determination of inter-individual differences in metabolic profiles.

Experimental: Dietary Intervention: Single intake of a supplement derived from artichoke by-products
Subjects will be asked to follow a low-(poly)phenol diet during the preceding two days and during the 48h of the dietary intervention.
On the day of the study, each volunteer will ingest the content of 6 capsules containing the amount of by-product artichoke powder able to deliver 197.4mg of HCAs after fasting overnight.
Blood samples at baseline (0 h) and different post-intake times (1, 2, 4, 7, 24 and 48 h) will be collected.
Urine samples will be collected in the following time intervals: 24h pre intake, 0-4, 4-8, 8-12, 12-24, and 24-48h.
|
A single dose of 6 capsules of dehydrated artichoke by-product (contains 197.4mg
HCAs) consumed within 15 minutes accompanied by 250ml of water
