Reaction: S-adenosyl-L-methionine + licodione = S-adenosyl-L-homocysteine + 2'-O-methyllicodione

Systematic name: S-adenosyl-L-methionine:licodione 2'-O-methyltransferase
Comments: As well as licodione [1-(2,4-dihydroxyphenyl)-3-(4-hydroxyphenyl)-1,3-propanedione], the 2"-hydroxy-derivative and isoliquiritigenin can act as acceptors, but more slowly.
