The purpose of the study is to perform pre-formulation studies for alpha-mangostin (α-mangostin)
and screening of additives (such as solid lipids, emulsifiers and cryoprotectants) and their combinations (ratio of
lipids, ratio of drug: lipid, ratio of emulsifier: co-emulsifier and concentration of cryoprotectant) used in the
formulation of solid lipid nanoparticles of α-mangostin. This screening is essential for the formulation of solid lipid
nanoparticles (SLNP) that provide small particle size and PDI, high entrapment efficiency and zeta potential. This
screening offers a rationale for selecting additives and their concentrations for formulating optimized SLNP. Pre-
formulation studies showed melting point of 181.5°C, partition coefficient of 0.359 and drug solubility of 0.3072,
0.4576, 0.4892 and 0.5782 mg/mL in 1.2, 6.8, 7.0 and 7.5 pH buffers respectively. Ultimately, the DSC thermogram
defines the sharp endotherm of α-mangostin at 195.98°C. Hot melt homogenization followed by ultrasonication
technique is used to develop solid lipid nanoparticles. Process parameters such as homogenization speed (15,000
rpm) and ultra sonication (6 minutes) was optimized based on particle size and PDI. The optimized formulation of
SLNP of α-mangostin contain 1:2:0.5:0.5:5 ratio of Drug: Solid lipid (0.8:1.2 ratio of Stearic acid: Precriol ATO5):
Poloxamer 407: Sodium taurocholate: Mannitol.
