Complex tannins are tannins made of a catechin bound to a gallotannin or elagitannin. Eugenigrandin a is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Eugenigrandin a can be found in guava, which makes eugenigrandin a a potential biomarker for the consumption of this food product.
