Macrophorins E, F and G were newly isolated from Botryosphaeria berengeriana, each showing potent antifungal activity similar to that of macrophorin A against phytopathogenic fungi B. berengeriana and Gibberella fujikuroi. Macrophorins E and G were identified as novel malonylated derivatives of macrophorin A, and F as a macrophorin E congener with a hydroxy-cyclohexenedione moiety instead of its epoxy-cyclohexenone one.
