title: [New anthraquinones in Rubia cordifolia roots].
abstract: From roots of Rubia cordifolia L. four anthraquinones are isolated: 1-hydroxy 2-methylanthraquinone and nordamnacanthal which have been already isolated in some Rubiaceae, physcion which seems to be new in this family and 1,4-dihydroxy 6-methyl-anthraquinone which seems to be a new quinizarin.
