The invention relates to the technical field of preparation of flavonoid compounds, in particular to a directional enrichment method of flavonoid compounds and a directional enriched product thereof. The directional enrichment method of the flavonoid compounds comprises the following steps: carrying out hot reflux extraction on a first mixed system of leguminous plants, a solvent and activated carbon, then carrying out first solid-liquid separation, and collecting a first liquid phase system; adjusting the pH value of the first liquid phase system by adopting an alkaline substance to obtain a second mixed system; and mixing the second mixed system with at least one of glycyrrhizic acid, glycyrrhetinic acid and glycyrrhizinate, carrying out heat treatment, carrying out second solid-liquid separation, and collecting a second liquid phase system. According to the method disclosed by the invention, all the steps are matched with one another, so that the flavonoid compounds in the leguminous plants can be directio
