The invention discloses a method for separating and extracting ipomoes batatas L. anthocyanidins, which comprises the following steps: cleaning, pulping and crushing the fresh ipomoes batatas L.; then, putting the crushed ipomoes batatas L. pulp into aqueous solution of acid ethanol, and extracting the solution with the aid of ultrasonic wave; filtering, compressing and concentrating the extract,adsorbing the extract by adopting NKA, washing the impurities by water, and eluting the extract by the aqueous solution of acid ethanol; and concentrating and drying the elution to obtain an ipomoes batatas L. anthocyanidins product. The method of the invention is characterized in that: ultrasonic wave-aid extraction and NKA separation and purification are adopted so as to ensure the efficient extraction of the anthocyanidins in the ipomoes batatas L. and ideal separation and purification effects and lay a foundation for the utilization and industrialized development of the ipomoes batatas L.resource ...
