This article reviews the research progress of anthocyanins and procyanidins at home and abroad, and systematically analyzes the research results related to procyanidins and anthocyanins from the dimensions of chemical structure, biosynthetic pathway, distribution area, separation and extraction method, color, efficacy, and future development potential. The comparison and induction of these two substances provide a reference for human beings to better develop and utilize these two substances.

This paper summarizes the research progress at home and abroad of anthotin and antholine, and systematically compares and summarizes the research results related to antholin and antholin from the dimensions of chemical structure, biosynthetic pathway, distribution area, separation extraction method, color, efficacy and future development potential, so as to provide reference for human beings to better develop and utilize these two substances.
