The liposomal delivery system can be applied to administrate the drug and other bioactive agent. There are currently a number of commercially available liposomal formulations. In this research, the nano-sized liposomes were prepared using the phosphatidyl choline. The size and size distribution and electric charge were investigated in the encapsulated liposome. To investigate the encapsulation into the liposome, the ursolic acid was used as a model agent. Because several pharmacological effects, such as, anti-tumor, hepatoprotective, anti-inflammatory, anti-ulcer, antimicrobial, anti-hyperlipidemic and antiviral, can be attributed to ursolic acid. In particular, its anti-inflammatory, anti-tumor, and antimicrobial properties are pertinent to the cosmetic industry. |
