Disclosed in the present invention is a preparation method for cannflavin compounds. The preparation method has advantages such as cheap and easily available raw materials, few reaction steps, short production period, and easy operation. The method comprises: first, condensing 4-hydroxy-3-methoxyacetophenone and diethyl carbonate (DEC) under an alkaline condition to obtain ethyl 4-hydroxy-3-methoxybenzoylacetate, next, reacting 1,3,5-trihydroxybenzene with geraniol to obtain (E)-2-(3,7-dimethyloct-2,6-dien-1-yl)benzene-1,3,5-triphenol; and finally, condensing ethyl 4-hydroxy-3-methoxybenzoylacetate and (E)-2-(3,7-dimethyloct-2,6-dien-1-yl)benzene-1,3,5-triphenol at high temperature to produce cannflavin A and/or cannflavin C, and then carrying out separation and purification to obtain pure cannflavin A and cannflavin C.
