Eupalitin is one of the O‐methylated flavonol‐exhibited enhanced cancer chemopreventive
agents. The current study highlights the structural determination of eupalitin and aims to
explore the antitumor activity of eupalitin in human prostate cancer cell (PC3) and its
underlying mechanism. Eupalitin structure was determined by using FTIR, 1H NMR, and
13C NMR. PC3 cells were treated with increasing concentrations of eupalitin, followed by …
