    Abstract: Provided is a process for the preparation of diosmin from hesperidin. The process involves the oxidation of acylated hesperidin with iodine or bromine in a C2-C4 carboxylic acid medium and subsequent treatment with an inorganic base to partially neutralize the acidic media. The process allows obtaining diosmin with low iodine or bromine content, avoiding the use of organic solvents.

    Abstract: Provided is a polynucleotide encoding a protein having an activity to transfer a sugar to the hydroxy groups at the 4′- and 7-positions of a flavone. The polynucleotide is selected from the group consisting of: (a) a polynucleotide which comprises a base sequence represented by SEQ ID NO: 1, 3, or 12; (b) a polynucleotide which hybridizes to a polynucleotide comprising a base sequence complementary to a base sequence represented by SEQ ID NO: 1, 3, or 12 under high stringency conditions, and encodes a protein having an activity to transfer a sugar to the hydroxy groups at the 4′- and 7-positions of a flavone; (c) a polynucleotide which encodes a protein comprising an amino acid sequence represented by SEQ ID NO: 2, 4, or 13; (d) a polynucleotide which encodes a protein comprising an amino acid sequence in which one or more amino acids have been deleted, substituted, inserted, and/or added in an amino acid sequence represented by SEQ ID NO: 2, 4, or 13 and having an activity to transfer a sugar to the hydroxy groups at the 4′- and 7-positions of a flavone; etc.
