Abstract:

To evaluate the quality of sesamin liposome, macroporous resin was used to separate the free sesamin and HPLC was used to determine the entrapment efficiency. This method has good linearity in the range of 5 to 200 μg/ml (r=0.9999).The precision RSD is less than 1.47%, the recovery of sesamin with blank liposome is 98.18%, and the average of recovery of blank liposomes through presaturated macroporous resin is 100.35% with an excellent adsorption of free sesamin. This method is simple and reproducible.

Key words: HPLC, macroporous resin, sesamin, entrapment efficiency
