title: A new anthraquinone from Gladiolus gandavensis.
abstract: A new anthraquinone, 1,6,7-trihydroxy-3-methoxyanthraquinone, along with three known compounds methyl trans-p-hydroxycinnamate, eugenin and 1,3,6-trihydroxy-8-methylanthraquinone, were isolated from the subterranean rhizomes of Gladiolus gandavensis Van Houtt. Their structures were established on the basis of spectroscopic data including 2D NMR techniques and chemical methods.
