Versuchsvorschrift

A hesperidin composition was obtained as a hesperidin-containing aqueous solution by a same procedure as in Example 1, except that a methylhesperidin preparation (manufactured by Hamari Chemicals Ltd., methylhesperidin content 100%, the same shall apply hereafter) was used instead of the EGCG preparation. Reaction conditions and the measurement result of a concentration of hesperidin and methylhesperidin in the composition are shown in Table 1.
