%X three new 4-phenylcoumarins, 5,7-dihydroxy-6-(2'-hydroxy-3'-methyl-3'-butenyl)-8-(4" -cinnamoyl-3"-methyl-1"-oxobutyl)-4-phenylcoumarin, 7-hydroxy-8-(4"-cinnamoyl-3"-methyl-1" -oxobutyl)-2'-(2-hydroxyisopropyl)-dihydrofurano(5',4':5,6)-4-phenylcoumarin, and 5,7-dihydroxy-8-(4"-cinnamoyl-3"-methyl-1"-oxobutyl)-4-phenylcoumarin, along with the known 4-n-propylcoumarins, 7-hydroxy-8-(4"-cinnamoyl-3"-methyl-1"-oxobutyl)-2',2'-dimethylpyrano (6',5':5,6)-4-n-propylcoumarin, 5-hydroxy-6-(4"-cinnamoyl-3"-methyl-1"-oxobutyl)-2',2' -dimethylpyrano(6',5':7,8)-4-n-propylcoumarin, the xanthone, 2,3-methylenedioxyxanthone and ¦Ä-tocotrienol were isolated from the organic extracts of kielmeyera reticulata stems .
