Abstract
Physiologically active, non-toxic, non-teratogenic and non-mutagenic huminates produced by oxidation of polyvalent phenols in aqueous alkaline medium at a reaction temperature under 40.degree. C., the pH value of the reaction medium always being over 9.0 during the oxidation and the supply of oxidant being proportioned so that the content of the quinones corresponding to the polyvalent phenols is always less than 0.5%, based on the polyvalent phenols used, and that the oxidation reaction is stopped when the quinone concentration decreases despite oxidant supply.
