The title compound (AME; systematic name: 3,7-dihy-droxy-9-meth-oxy-1-methyl-6H-benzo[c]chromen-6-one), C(15)H(12)O(5), was isolated from an endophytic fungi Alternaria sp., from Catharanthus roseus (common name: Madagascar periwinkle). There is an intramolecular O-H⋯O hydrogen bond in the essentially planar mol-ecule (r.m.s. deviation 0.02 Å). In the crystal, the molecule forms an O-H⋯O hydrogen bond with its centrosymmetric counterpart with four bridging inter-actions (two O-H⋯O and two C-H⋯O) ...[more]
