title: New anthraquinones from Gladiolus gandavensis.
abstract: Two new anthraquinones, methyl 8-hydroxy-3-methoxy-6,7-methylenedioxy-1-methylanthraquinone-2-carboxylate (gandavensin A, 1) and methyl 8-hydroxy-3,6,7-trimethoxy-1-methylanthraquinone-2-carboxylate (gandavensin B, 2), have been isolated from the light petroleum extract of the subterranean corm of Gladiolus gandavensis Van Houtt., along with methyl 8-hydroxy-3,6-dimethoxy-1-methylanthraquinone-2-carboxylate (3), methyl trans-p-methoxycinnamate (4), 5,7-dimethoxy-2-methylchromone (5), and 5-hydroxy-2-hydroxymethyl-7-methoxychromone (6). Their structures were elucidated on the basis of spectral data.
