This kind of chemical could be obtained through very simple ways in the lab. First prepare the reactant of [1,3,5]triazine ,1-(2,4,5-trihydroxyphenyl)-2-(4-hydroxyphenyl)ethanone and the reagent of bortrifluorid-ether, acetanhydride and the solvent of acetic acid diethyl ether, and then let them react under the heating condition. Finally, you could get 6,7-dihydroxy-3-(4-hydroxy-phenyl)-chromen-4-one (6,7,4'-Trihydroxyisoflavone). Through this way, the productivity is about 58%. There are also other reaction ways to produce this chemical. 7-hydroxy-3-(4-hydroxy-phenyl)-6-methoxy-chromen-4-one could react in the reagent of brevibacterium epidermides and the solvent of dimethylsulfoxide methanol for about 48hours, and then you could get it with the productivity of 30%.

In addition, you could obtain the molecular structure by converting the following data information:
SMILES: O=C\1c3c(O/C=C/1c2ccc(O)cc2)cc(O)c(O)c3
