highlighting that structural modification of naturally occurring metabolites can enhance their intended pharmacological functions.Three new polycyclic phenol derivatives, 2-acetyl-4-hydroxy-6H-furo [2,3-g]chromen-6-one (1), 2-(1',2'-dihydroxypropan-2'-yl)-4-hydroxy-6H-furo [2,3-g][1]benzopyran-6-one (2) and 3,8,10-trihydroxy-4,9-dimethoxy-6H-benzo[c]chromen-6-one (8), along with seven known ones (3-7, 9 and 1 were isolated for the first time from the leaves of Spermacoce latifolia. Their structures were determined by spectroscopic
