“…The stabilizing action of chalcones on the vascular wall, vasodilating and antioxidative activity have been reported (Opletalova et al, 2003). The crystal structures of 1-phenyl-3-(3,4,5-trimethoxyphenyl)prop-2-en-1one (Teh et al, 2006) (Yathirajan et al, 2007); 3-(4-chlorophenyl)-1-(3-hydroxyphenyl)prop-2-en-1-one (Butcher et al 2007a). As a part of our ongoing studies on chalcones, a new chalcone, C 15 H 11 ClO, was prepared and the crystal structure is reported.…”
