title: Constituents of Eremurus chinensis.
abstract: A novel bianthraquinone glycoside, 8-O-beta-D-glucopyranosyl-1,1', 8'-trihydroxy-3,3'-dimethyl-2,7'-bianthraquinone (1); two naphthalene derivatives, 2-acetyl-1-hydroxy-8-methoxy-3-methylnaphthalene (2) and 2-acetyl-1, 8-dimethoxy-3-methylnaphthalene (3); and a novel pre-anthraquinone, 1-oxo-4(S),9-dihydroxy-8-methoxy-6-hydroxymethyl-1,2,3, 4-tetrahydroanthracene (4), were isolated from Eremurus chinensis. Their structures were established by spectroscopic and chemical methods. In addition, the known compounds chrysophanol, chrysophanol 8-methyl ether, aloesaponol III 8-methyl ether (5), and 10-(chrysophanol-7'-yl)-10-hydroxychrysophanol-9-anthrone were also isolated and identified from this plant.
