The contents and the particle size changes of PMO-H during 3 months of stability test under acceleration condition at 40 °C/75% RH. Proportion of oleanolic acid in PMO-H: 100 ± 1.6% (0 month), 99.9 ± 0.2% (1 month), 99.5 ± 0.2% (2 month), and 99.3 ± 0.2% (3 month). Particle size of PMO-H: 55.3 ± 6.5 nm (0 months), 54.6 ± 7 nm (1 month), 51.0 ± 5.56 nm (2 months), and 49.6 ± 5 nm (3 months)
