Anthraquinones from Hedyotis pinifolia

Le Hoang Duy, Nguyen Kim Phi Phung


Hedyotis pinifolia Wall ex G.Don (Vietnamsese name An đin l¸ th«ng), family of Rubiaceae, has not yet been chemically studied. From the aerial parts of H. pinifolia, four anthraquinones had been isolated: 1,6-dihydroxy-7-methoxy-2-methylanthraquinone (1), 1,6-dihydroxy-2-methylanthraquinone (2), 3,6-dihydroxy-2-methylanthraquinon (3) and 1,3,6-trihydroxy-2-methylanthraquinone (4). Their chemical structures were established by spectroscopic analysis.
