Abstract

The conjugate of oleanlic acid with adenine was synthesized and it could be gelled in mixed solvents of THF and water, but no gel was formed in the single organic solvent. The self- aggregation behaviour and physical properties of the organogel were characterized by 1H NMR, FT-IR, and scanning electron microscopy. The morphology and the stability of the gel were remarkably affected by the uracil derivative through destroying hydrogen-bonding.
