Alternariol 9-O-methyl ether

Alternariol 9-O-methyl ether

The title compound (AME; systematic name: 3,7-dihydroxy-9-methoxy-1-methyl-6H-benzo[c]chromen-6-one), C15H12O5, 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 e...
