|Abstract: ||Five new prenylated 4-phenylcoumarins were isolated from the hexane extract of the stems of Kielmeyera reticulata, 7-hydroxy-8-(4-cinnamoyl-3-methyl-1-oxobutyl)-4-phenyl-2′,2′-dimethyl 2H,6H-benzo[1,2-b:3,4-b′]-dipyran-2-one, 7-hydroxy-8-(4-hydroxy-3-methyl-1-oxobutyl)-4-phenyl-2′,2′-dimethyl-2H,6H-benzo [1,2-b:3,4-b′]-dipyran-2-one, 5-hydroxy-6-(4-cinnamoyl-3-methyl-1-oxobutyl)-4-phenyl-2′,2′-dimethyl-2H,6H-benzo [1,2-b:3,4-b′]-dipyran-2-one, 5,7-dihydroxy-6-(4-cinnamoyl-3-methyl-1-oxobutyl)-8-(3-methyl-2-butenyl)-4-phenyl-2H-1-benzopyran-2-one, and 5,7-dihydroxy-6-(4-hydroxy-3-methyl-1-oxobutyl)-8-(3-methyl-2-butenyl)-4-phenyl-2H-1-benzopyran-2-one, These compounds were identified from spectral evidence and compared with literature data.|
