1-Methyl anthraquinones and their biogenetic precursors from Stereospermum personatum.
Two novel 1(17)-methyl anthraquinones, sterequinone-A and -D, their biogenetic precursors sterequinone-B, -C, and a new naphthoquinone sterequinone-E along with a known naphthoquinone, sterekunthal-B, have been isolated from the petroleum ether extract of stem bark of Stereospermum personatum. Their structures were established using spectroscopic methods.
