Recent Advances in Polyphenol Research.
Plant phenolics are secondary metabolites that constitute one of the most common and widespread groups of substances in plants. Polyphenols have a large and diverse array of beneficial effects on both plants and animals. For example they are famous as antioxidants, hormones, constituents of essentia...
