wedeloside, a new flavanone, 7,4′-dihydroxy-8,3′-dimethoxyflavanone and its related chalcone, together with the 4′- O -β- d -glucopyranoside of the latter, and a number of known compounds were isolated from the aerial parts of Wedelia asperrima . Their structures were established by spectroscopic techniques and by synthesis of the flavanone and chalcone.
