Preparation and characterization of quercetin-loaded lipid liquid crystalline systems

- We examine the mixtures of SPC and GDO as encapsulation matrices for quercetin (QU).
- SPC/GDO-based formulations can incorporate relatively high amounts of QU.
- At high SPC content, the loaded QU has no effect on the nanostructure of H2 phase.
- At low SPC content, QU slightly increases the unit cell dimensions of Fd3¯m phase.
