Eriodictyol

Patients consumed a polyphenol-rich dietary supplement (commercial lemon, orange, pomegranate, olive, grape, cocoa, curcuma and broccoli extracts), mainly rich in simple phenolics such as hydroxytyrosol and the polyphenols procyanidins, hesperidin, eriocitrin, curcumin, resveratrol, punicalagin and ellagic acid. Cocoa extract also contains the methylxanthines theobromine and caffeine.

Participating patients did not consume the supplement but provided biological samples to the trial

Patients consume 3 capsules/day (474 mg phenolics/day) from the biopsy-confirmed breast cancer diagnosis to the surgery

The aim is to characterise the metabolic profiling of dietary polyphenols in normal and malignant breast tissues from breast cancer patients.

The objective of this exploratory trial is to determine the disposition and characterise the metabolic profiling of dietary polyphenols in normal and malignant glandular breast tissues from newly diagnosed breast cancer patients.

The patients consumed a polyphenol-rich dietary supplement containing 37 different phenolics and 2 methylxanthines (theobromine and caffeine) from the diagnosis to the surgery. The metabolic profiling was characterized in normal and malignant breast tissues as well as plasma and urine using UPLC-ESI-QTOF-MS/MS.

Metabolic Profiling of Dietary Polyphenols and Methylxanthines in Normal and Malignant Mammary Tissues From Breast Cancer Patients

Quantification of dietary polyphenols and methylxanthines in normal and malignant mammary tissues from breast cancer patients using ultra-high resolution liquid chromatography coupled to quadrupole-time-of-flight mass spectrometry (UPLC-ESI-QTOF-MS/MS).

* Quantification (pmol/g) of each phenolic-derived metabolite in breast tissues.
* Quantification (pmol/g) of each methylxanthine-derived metabolite in breast tissues.
