The invention belongs to the field of medicine synthesis, and in particular relates to a preparation method and application of tricetin. The method comprises the following steps: performing hydroxy protection to form a compound 3 by using 2,4,6-trihydroxyacetophenone as a starting material, performing an acylation reaction on the compound 3 and 3,4,5-trimethoxybenzoyl chloride to form a compound 4, performing Baker-Venkataranan rearrangement on the compound 4 to form a compound 5, performing cyclization on the compound 5 under catalysis of H2SO4/HOAc to form a compound 6, and finally performing pyridine hydrochloride deprotection on the compound 6 to form the tricetin, wherein in the step of synthesizing the compound 5, when NaOH is selected as a base and pyridine is selected as a solvent,the yield is greatly improved, and the reaction is relatively stable. According to the method provided by the invention, pharmacological activity experiments show that the compound synthesized by themethod has anti-nerve damage activity, so that the compound has better application prospects in treating nerve damage-related diseases.
