hydrogenated soybean phospholipid (HSPC) and distearylethanolamine-polyethylene glycol 2000 (DSPE-PEG2000) were used as raw material
use of reverse phase evaporation method to prepare a new type of intelligent drug controlled release polymer material which encapsulates the active ingredient berberine of traditional Chinese medicine coptis (berberine thermosensitive liposomes). The morphology and property of the product were characterized by Transmission Electron Microscope (TEM)
UV spectrophotometer(UV)
Zeta potential and Phase Analysis Light Scattering (ZetaPALS) and Differential Scanning Calorimeter (DSC). The release rule
in vitro
of the product was studied as well. The experimental results showed that the thermosensitive liposomes with a particle of berberine were synthesized successfully. Confirmed that the size of the product is 311 nm
the phase transition temperature is 317. 35 K
the effect that the temperature-sensitive liposome encapsulates the berberine is good
the encapsulation efficiency was 74%
in vitro
release kinetics model of the berberine thermosensitive liposomes accorded with Ritger-Peppas equation.
