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.
从中国独尾草中分离得到一种新型双蒽醌苷，8 - O - β - D - 吡喃葡萄糖基 - 1,1', 8'- 三羟基 - 3,3'- 二甲基 - 2,7'- 双蒽醌（1）；两种萘衍生物，2 - 乙酰基 - 1 - 羟基 - 8 - 甲氧基 - 3 - 甲基萘（2）和2 - 乙酰基 - 1, 8 - 二甲氧基 - 3 - 甲基萘（3）；以及一种新型前蒽醌，1 - 氧代 - 4(S),9 - 二羟基 - 8 - 甲氧基 - 6 - 羟甲基 - 1,2,3, 4 - 四氢蒽（4）。通过光谱和化学方法确定了它们的结构。此外，还从该植物中分离并鉴定出了已知化合物大黄酚、大黄酚8 - 甲醚、芦荟皂醇III 8 - 甲醚（5）以及10 - （大黄酚 - 7'- 基）- 10 - 羟基大黄酚 - 9 - 蒽酮。
