Abstract:
Alpha-mangostin is a substance with many beneficial aspects such as antioxidant, antitumoral, and antibacterial. The forming into complex with Beta-cyclodextrin is a good method to develop into pharmaceutical industry. However, they are hard to make complexation because Alpha-mangostin is solid at room temperature and also has a low solubility in water. The molecular dynamics simulation (MD) was employed to check the complex between Beta-cyclodextrin and Alpha-mangostin. The program demonstrates only binary complex between Alpha-mangostin and Beta-cyclodextrin. This research aims to study the effect of the reaction time, solvent and temperature on the complexation. The results showed that a ratio of Beta-cyclodextrin to Alpha-mangostin was 1:1 for binary complex. Binary complex was found in water whereas the complexation in alcohol was binary and ternary. Mathematical analysis was employed to determine both complexes. The result shows 48 hours is the equiblibrium of complexation and the temperature at 45 degree celcius is the most suitable for complexation in ethanol solution. Moreover, an addition of alcohol can decrease the binary complexes while the ternary complex was found at high alcohol concentration. At high alcohol concentration (>10%), More ternary complex has found in propanol and isopropanol while binary complex was found in methanol and ethanol.
