Objective: To study the binding ratio of isorhamnetin-3-O-neohesperidoside with bovine serum protein in vitro. Method: Equilibrium dialysis and HPLC were employed to determine the binding rate of isorhamnetin-3-O-neohesperidoside and calf serum. And homology modeling and molecular docking were employed to simulate their interaction. Result: The balance time of dialysis was 16 hours approximately. The serum protein binding rate of isorhamnetin-3-O-neohesperidoside at low
middle and high concentrations (2
4
8 mg·L-1) were (43.23±2.23)%
(45.16±3.12)% and (44.71±3.25)%
respectively. The molecular docking showed that isorhamnetin-3-O-neohesperidoside was able to bind to residue of bovine serum albumin and formed six hydrogen bonds. Conclusion: Isorhamnetin-3-O-neohesperidoside has a medium extent of protein bind with bovine calf serum.
