What is Troxerutin?

Troxerutin is a semi-synthetic manufactured derivative of the natural substance rutoside. This flavonoid is present in many (even indigenous) plants, but is mainly extracted industrially from the Japanese Pagoda Tree, which is native to Japan and China. Troxerutin is transposed into an easily water-soluble substance by the hydroxyethylation of phenol groups. Troxerutin is reabsorbed by the gastrointestinal tract better than rutoside is.
