At the half-wavelength position, a significant drawing force reduction of 66.8% (from 22.5 N to 7.45 N) was observed with the ultrasonic amplitude and drawing speed of 9μm and 100 mm/s, respectively. At the quarter-wavelength position, however, the corresponding percentage reduction is only 21%. The phenomenon could be explained by the elastic stretching oscillation of the wire based on the stress superposition hypothesis.The antiradical capacity and mechanisms of two representative coumestan-type compounds, namely isosoja
