Generation of supramolecular hydrogel from biocompatible supramolecular building blocks has become an area of tremendous research investigation because of it's potential use in biomedical sciences, food industries, cosmetics, etc. In recent years, the biocompatible nano‐sized trieterpenoid molecules have gained significant attention of the scientific community as supramolecular building blocks because of its unique molecular structures. Herein, we report the hierarchical self‐assembly properties of sodium and potassium salts of a naturally ocurring triterpenoid arjunolic acid in water and aliphatic alcohols. An interesting evolution of vesicular self‐assemblies of the molecules at a lower gelator concentration to giant fibrillar assemblies at a higher gelator concentration affording stable gels were obseved. The vesicular self‐assemblies have been utilized for the entrapment and controlled release of various fluorophores including the anticancer drug doxorubicin at physiological pH.
