description The invention relates to a method for purifying solanesol through urea adduction fractionation from crude solanesol. The method comprises the following steps: dissolving a defined amount of crude solanesol, filtering, saponifying, extracting to obtain a saponified substance of which the solanesol content is 30-40%, concentrating the saponified substance, dissolving, crystallizing, and performing urea adduction fractionation to crystals three times to ensure that the solanesol purity is up to above 90% and the yield is up to about 70%. By adopting the method to purify solanesol from tobacco extract, column chromatography is not required, the process is simple, impurities such as waxiness, fatty acids and the like can be effectively removed and the yield of solanesol is high.
