l-Menthyl α-D-glucopyranosyl-(1→4)-α-D-glucopyranoside (l-α-MenG2), an α-maltoside of l-menthol, was synthesized through a three-step enzymatic reaction. We found that l-α- MenG 2 possesses the properties of a low-molecular-weight gelator. Aqueous solutions containing l-α-MenG2 at concentrations above 30 g L-1 show a thermally reversible sol-gel transition. The sol-gel transition temperature of the aqueous l-α-MenG2 solution increases with l-α-MenG2 concentration: 12 °C at 30 g L-1 and 24 °C at 250 g L-1. d-Menthyl and d-isomenthyl α-maltosides were also synthesized enzymatically, but their aqueous solutions showed no sol-gel transition.
