尿石素A

Description:

Urolithin A is a metabolite compound resulting from the transformation of ellagitannins by the gut bacteria.  It belongs to the class of organic compounds known as benzo-coumarins or dibenzo-α-pyrones. Its precursors – ellagic acids and ellagitannins – are ubiquitous in nature, including edible plants, such as pomegranates, strawberries, raspberries, and walnuts.Since the 2000s, urolithin A has been subject of preliminary studies regarding its possible biological effects.

Urolithin A is not known to be found in any food source. Its bioavailability mostly depends on individual microbiota composition, as only some bacteria are able to convert ellagitannins into urolithins.
