First Organogelation Study of Ursolic Acid, a Natural Ursane Triterpenoid

摘要

The self-assembly property of ursolic acid (UA) without any modification was reported here for the first time. The results showed that ursolic acid could aggregate into organogels in bromobenzene and some alcoholic solvents. It was proved that the driving forces for gel formation were intermolecular hydrogen bonding and packing interaction between the rigid backbones of ursolic acid through Fourier-transform infrared (FT-IR) spectra.
