Abstract
⺠We investigate the binding mechanism of vitexin to human serum albumin (HSA) by different multi-spectroscopic techniques under simulated physiological conditions. ⺠Vitexin can strongly quench the ï¬uorescence of HSA through a static quenching mechanism. ⺠The interaction of vitexin with HSA is driven mainly by hydrogen bond and van der Waals forces. ⺠The binding distance between HSA and vitexin is 4.16 nm, and vitexin is mainly located in the region of site I (subdomain IIA). ⺠The binding of vitexin to HSA can induce conformational changes of HSA.
