Abstract:
Objective To increase the water solubility of curcumin constituents by three kinds of food grade surfactants, and to study the effect of surfactants on the quality standard and stability and anti-hepatic fibrosis in vivo of curcumin solution. Methods The high-speed dispersion method was used to prepare the solution of curcuminoids-surfactants. The qualitative analysis of curcuminoids was confirmed by LC-MS/MS. HPLC-DAD fingerprinting was established and quantitative analysis was conducted. And the effects on anti-liver fibrosis of different concentrations curcumin ratio solution were evaluated by rat model. Results The maximum water solubility of curcumin constituents was 1.387 mg/mL. LC-MS/MS analysis showed that the structure of curcuminoids were stable; The results of fingerprinting analysis demonstrated that the similarity of 18 batches of samples were higher than 99%. The contents of curcumin, demethoxycurcumin and bisdemethoxycurcumin in different batches of samples were stable with the RSD of 1.60%, 2.24%, and 3.74%. The rat model of hepatic fibrosis showed that the contents of AST and ALT in free curcumin suspension group were (64.1 ± 20.3) and (45.1 ± 13.9) U/L, respectively, while that solution of curcuminoids-surfactants group was (19.4 ± 8.7) and (11.8 ± 4.9) U/L. Conclusion The solubility of curcuminoids was increased 517 times compared with the free state (2.677 μg/mL) after solubilization with surfactants, and repeated tests indicated that the structure and contents of curcuminoids were stable; the solubilized curcuminoids exhibited better anti-liver fibrosis effects than the free.
