中文摘要：

试图学习 Monochasma savatierii Franch 的化学成分。化学成分被列层析与硅石胶化孤立并且反复净化了的方法， Rp-C18， Sephadex LH-20 并且由红外， MS 和 NMR 识别了。结果和八混合物作为 7 被获得并且识别， 8-dehydroboschnialactone (1 ) ， argyol (2 ) ， liquirtigenin (3 ) ， -sitosterol (4 ) ， p-hydroxycinnamic 酸(5 ) ， 2-hydroxy-4-methoxybenzonic 酸(6 ) ， p-hydroxyphenylethanol (7 ) ， protocatechuic 酸(8 ) 。结论化合物 1 第一次从生来的来源被获得，其它第一次从这植物被孤立。

英文摘要：

AIM： To study the constituents in the roots of Achyranthese bidentata Bl. METHODS： D-101 porous polymer resin column, normal-phase silica gel column chromatography, revised-phase medium pressure column chromatography, Sephadex LH-20 and prep-HPLC were used for the separation, and spectroscopic techniques were employed for the identification of the isolated compounds. RESULTS： Five saponins were isolated and elucidated as achyranthoside C （1）, achyranthoside D （2）, chikusetsusaponin Ⅳ （3）, ginsenoside Ro （4） and zingibroside R1 （5）. CONCLUSION： Compound 1 was obtained from natural source for the first time, and compound 3 was reported from the family of Amaranthaceae for the first time.
