catechol tannins Explanation: "Condensed tannins: These tannins are resistant to hydrolysis and they derive from the flavonols, catechins and flavan-3, 4-diols. On treatment with acids or enzymes they are decomposed into phlobaphenes. On dry distillation condensed tannins produce catechol. These tannins are called *catechol tannins*. These tannins are found in cinchona bark, male fern, areca seeds, tea leaves and wild cherry bark, bahera fruits, Amla, etc. https://www.yourarticlelibrary.com/pharmacognosy/tannins/tannins-classification-properties-and-chemical-tests/49892 Reference: http://cameo.mfa.org/wiki/Catechol_tannin |
