Urolithine

from Wikipedia, the free encyclopedia

The urolithines are a group of natural phenols that are formed when ellagic acid and ellagitannins are broken down in the digestive tract . Chemically, the urolithines can be described as hydroxylated benzopyran-6-ones .

Occurrence

Urolithines are not very common in nature. They usually come from plants rich in ellagitannin, such as B. the tamarisk Tamarix nilotica , the pomegranate and in Mumijo .
