Stability of ellagitannins in processing products of selected Fragaria fruit during 12 months of storage

Abstract

Berries of the genus Fragaria, i.e., strawberries and wild strawberries, contain a high concentration of ellagitannins (ETs)-depending on the variety, from 50 to 300 mg/100 g fresh weight (Gasperotti

Urolithins and Their Precursors Ellagic Acid and Ellagitannins: Natural Sources, Extraction and Methods for Their Determination

“…ETs and EA display characteristic UV spectra with maximum absorbance below 270 nm [124]. They have been frequently determined in pomegranate [124,125], strawberries [126,127], Rubus berries and their leaves [128,129], chestnuts [130], as well as waste products of walnuts, chestnuts, pomegranates [131], and pomegranate peels [132]. Mass spectrometry detectors also proved to be valuable tools mainly for the identification of ETs and EA, usually in combination with HPLC/DAD systems.…”
