Anthraquinones from hedyotis herbacea

A new anthraquinone, 2-hydroxymethyl-10-hydroxy-1,4-anthraquinone (1), was isolated from Hedyotis herbacea along with three other known derivatives: 1,4-dihydroxy-2-hydroxymethylanthraquinone (2); 2, 3-dimethoxy-9-hydroxy-1,4-anthraquinone; and 1,4-dihydroxy-2, 3-dimethoxyanthraquinone. The structure of 1 was determined based on analysis of its spectroscopic data.
