The additional new metabolites, named phyllostine (II) and 3-chloro-2, 5-dihydroxybenzyl alcohol (III) from the cultural filtrates of Phyllosticta sp. have been isolated. The chemical structure of II have been established by spectral studies and chemical conversion from the known I, and the chlorine-containing metabolite (III) by spectral and synthetic studies. The metabolite (II) exhibits the similar phytotoxic effects as I, but the metabolite III does less phytotoxicity than I and II on the leaf test.
