Introduction
Flavonoids are the most important and effective constituents in the thorns of Gleditsia sinensis Lam., which have been known to show antimicrobial, antiviral, anticancer, and anticoagulant activities. However, efficient extraction and separation methods for these flavonoids are not currently established.
Objective
To develop an efficient method for efficient extraction and rapid separation...
The affinities of apigenin, chrysin, daidzein and quercetin for human serum albumin (HSA) were studied in the presence and absence of Pb2+, Ni2+, Zn2+, Mg2+ and Mn2+. The fluorescence intensities of HSA decrease remarkably with increasing concentration of these four flavonoids. Adding apigenin and chrysin resulted in blue-shifts of HSA from λem=336 to 332 nm and 330 nm, respectively. However, quercetin...
