Objective: To optimize preparation technology of SOD from Panacis Quinquefolii Radix liposomes and investigate its properties. Method: Anti-phase evaporation method was used to prepare SOD from Panacis Quinquefolii Radix liposomes
with entrapment efficiency as index
effects of lecithin-cholesterol ratio
volume of phosphate buffer and amount of SOD from Panacis Quinquefolii Radix on preparation technology was investigated by orthogonal design
then studied particle size
in vitro release and stability of SOD from Panacis Quinquefolii Radix liposomes. Result: Optimum preparation technology was:lecithin-cholesterol (4: 1)
volume of phosphate buffer 12 mL
the amount of SOD from Panacis Quinquefolii Radix 10 mg.These prepared liposomes was uniform with average particle size of 480 nm and entrapment efficiency of 71.35%. Conclusion: These prepared liposomes had high entrapment efficiency and good stability with certain sustained-release effect.
