A system and method for purifying coenzyme Q.sub.10 are provided. The method includes: passing a CoQ.sub.10-containing crude product through a first chromatographic column to obtain a first CoQ.sub.10-containing intermediate product. The method further includes preparing, based on the first CoQ.sub.10-containing intermediate product, a second CoQ.sub.10-containing intermediate product. The method further includes passing the second CoQ.sub.10-containing intermediate product through a second chromatographic column to obtain a third CoQ.sub.10-containing intermediate product. The method further includes obtaining purified CoQ.sub.10 product by purifying the third CoQ.sub.10-containing intermediate product.
