Preparation and Quality Evaluation of Formononetin Inclusion Compound Liposome / 中国药房

OBJECTIVE: To prepare Formononetin (FMN) inclusion compound liposome and evaluate its quality. METHODS: FMN inclusion compound liposome was prepared by film dispersion method. The morphology, particle size, Zeta potential, encapsulation efficiency and in vitro release properties were studied. RESULTS: The particle size, Zeta potential and encapsulation efficiency of prepared FMN inclusion compound liposome were (255. 34 ± 12. 87) nm, (25. 32 ± 3. 51) mV, (81. 63 ± 0. 79)％, respectively (n=3). The 24 h accumulative release rate of prepared FMN inclusion compound liposome was 56. 12％. CONCLUSIONS: FMN inclusion compound liposome with good sustained-release effect is prepared successfully and in line with related quality standard.
