title = "Rubiasins A-C, new anthracene derivatives from the roots and stems of Rubia cordifolia",
abstract = "Three new anthracene derivatives, rubiasins A-C (1-3), were isolated from the combined roots and stems of Rubia cordifolia, and their structures were elucidated by spectroscopic analysis. Their absolute configurations were determined by Mosher ester methodology. A known compound, mollugin (4), was obtained as an active antiproliferative principle by bioassay-monitored fractionation using a human colon cancer (Co12) cell line. (C) 2000 Elsevier Science Ltd.",
