Abstract:
Objective To explore the impacts of different excipients on physical and chemical properties of Acteoside solid lipid nanoparticles (Acteoside-SLN),and make experimental evidence for the study of prescription SLN.Methods Emulsification-evaporation was appropriate for the preparation of Acteoside-SLN.Single variable method was used for fumbling the effects of Compritol 888 ATO,glyceryl monostearate,soy lecithin,Myrj52 and other accessories on the physicochemical properties including nanoparticles particle size,encapsulation efficiency and characterization dispersity (PDI) of Acteoside-SLN.Transmission electron microscope was used to observe the morphology of Acteoside-SLN and the structure of Acteoside in SLN was measured by XRD.Results With the increasing of the amount of Compritol 888 ATO,the particle size of nanoparticles decreased significantly,encapsulation efficiency decreased slightly,PDI increased;With the increasing of amount of glycerol monostearate,particle size increased obviously,encapsulation efficiency decreased slightly,and PDI decreased;With the increasing of the amount of lecithin,particles size increased significantly,encapsulation efficiency decreased,and PDI decreased;With the increasing of Myrj52 amount,the nanoparticles particle size decreased,encapsulation rate and PDI increased slightly.The appearance of Acteoside-SLN was presented uniform spherically.Acteoside was wrapped in SLN in a molecular dispersion state.Conclusion Various additives have a greater impact on physicochemical properties of Acteoside-SLN,and inspiration for prescription screening of SLN is supplied by this study.
