Two triterpenoid–peptide conjugates containing oleanolic acid and glycyrrhetinic acid were synthesized and the properties of self-assembly into organogels were studied systematically. The results showed that the xerogels could selectively adsorb dyes from water and it could be utilized in water purification by removing toxic dyes. In addition, the formation of supramolecular gels was associated to basicity increase by employing pH-indicator dyes in water.
