Two new phenyl compounds, methyl 2, 5-dimethoxy-3, 4-methylenedioxybeenzoate (la) and 4, 5-dimethoxy-2,3-methylenedioxybenzoic acid (2a) were isolated from the fruit bodies of the fungus Antrodia cinnamomea. The structures of these compounds were elucidated by the usual spectroscopic methods and by 2D NMR techniques.
