Summary:The invention discloses a preparation method of a natural active compound of mango aglycone. The preparation method comprises the following steps: getting 2-halogenate-4, 5-dimethoxy benzoyl chloride (halogen can be helium atom or bromine atom) and 1, 3, 5-trimethoxy benzene as the raw materials; and carrying out Friedel-Crafts acylation reaction (condensation) and demethylation cyclization to same to efficiently obtain the high-purity mango aglycone. According to the preparation method disclosed by the invention, the raw materials are cheap and easy to obtain; fewer synthesizing steps are carried out, therefore, the operation can be simpler, more convenient, safer and more efficient; and the preparation method is easy to control; the synthesized product is high in purity, and has high quality; and the preparation method is suitable to be applied to industrial production.
