Abstract:

An emulsion containing curcumin was obtained by high pressure homogenization. According to the particle size of the emulsion, the technological parameters for preparation were optimized. The stability of the curcumin emulsion under light and at high temperature was determined. Further, the curcumin emulsion was used to control the anti-inflammatory activities in lipopolysaccharide LPS induced cell model in vitro and TPA induced animal model, as well as its regulating effect on inflammatory factors. The results show that the optimized condition of high pressure homogenization for preparing the curcumin emulsion is being homogenized at 60 MPa for 1 h at 35 ℃, and repeated for 6 cycles. The particle size of the curcumin emulsion thus prepared is (200±50) nm and the curcumin content is 5%. The curcumin emulsion and the cosmetic formulas thereof have good stability under light and at 60 ℃. The curcumin emulsion has a significant inhibitory effect on NO induced by LPS when the concentration of the curcumin emulsion is 1-50 μg/mL, and the inhibition rate of the curcumin emulsion with 0.4 mg/ear against TPA induced ear edema in mice is larger than 57%. The mechanism may be through inhibiting the secretion of key cytokines IL-6 and TNF-α in the inflammatory reaction, thus exerting anti-inflammatory effect.

Key words: curcumin, emulsion, anti-inflammatory, stability
