PROBLEM TO BE SOLVED: To provide a gelling agent which comprises a low molecular weight compound which is easily synthesized and handled, is applied for gelling of solvents, especially various kinds of organic solvents and changes its gelling ability if required. SOLUTION: This gelling agent comprises a sugar benzylidene derivative obtained through dehydrocondensation of a monosaccharide having a pyranose ring structure and benzaldehyde. A preferable example of the sugar benzylidene derivative is methyl-4,6-O-benzylidene-β-D-galactopyranoside, methyl-4,6-O- benzylidene-α-D-glucopyranoside, methyl-4,6-O-benzylidene-α-D-galactopyranoside, methyl-4,6-O-benzylidene-α-D-mannopyranoside or p-nitrophenyl-4,6-O- benzylidene-α-D-glucopyranoside.
