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.

A method of preparing a Senna obtusifolia seed extract rich in anthraquinones and a galactomannan extract includes the following steps: (1) crushing Senna obtusifolia seeds into a Senna obtusifolia seed powder; (2) extracting the Senna obtusifolia seed powder with 40-85% ethanol, filtering to obtain an extract solution and a residue; (3) concentrating the extract solution under vacuum to obtain a concentrated extract solution, spray-drying the concentrated extract solution to obtain the Senna obtusifolia seed extract; (4) extracting the residue with membrane filtered water, conducting a centrifugation to obtain a supernatant; (5) adding ammonium sulfate and ethanol to the supernatant to form a two-phase aqueous system, collecting a bottom layer of the two-phase aqueous system; and (6) conducting an ultrafiltration of the bottom layer with a cut-off molecular weight of 50 k-200 k to obtain a galactomannan extract solution, drying the galactomannan extract solution under vacuum to obtain the galactomannan extract.
