(57) [Summary] [Objective] The present invention aims to develop rubusoside derivatives having better sweetness. [Structure] In the sweet glycoside rubusoside, a β-D-fructofuranosyl group is bonded to the 6-position hydroxyl group of the β-D-glucopyranosyl group which is ester-bonded to the 19-position carboxyl group at the 2-position, and a 13-position hydroxyl group is further added. To the 4-position hydroxyl group of the β-D-glucopyranosyl group which is ether-bonded to [α-D -Glucopyranosyl- (1 → 4)] n (where n is 1 Rubusoside derivative having an ether bond. |
