ABSTRACT
Objective To establish a RP-HPLC method for the determination of encapsulation efficiency (EE) and medicine loading (ML) in β-elemene-loaded Nano Polymeric Micelles; To study its release characteristic in vitro. Methods DSPE-PEG2000 was used as carrier to prepare medicine-loaded micelles. EE and ML were determined by petroleum ether extraction method, and its release characteristic in vitro was studied by dialysis method. Results The average EE and ML ofβ-elemene-loaded Nano Polymeric Micelles were 89.47%and 8.33%, respectively. Its release characteristic was slow. Conclusion The method for EE and ML determination is simple and accurate, and the prepared micelles have the property of sustained release.
