Method for extracting purified solanesol from potato leaf

The invention discloses a method for extracting purified solanesol from a potato leaf. The method uses the potato leaf as a raw material to produce a solanesol product with purity of over 95 percent through microwave assisted extraction, saponification, column chromatography, crystallization, recrystallization and the like. Compared with the prior art, the method has the characteristics of high selectivity, mild reaction condition, simple process, short production period, large batch, high yield and purity of the solanesol and convenience for industrialization.
