Abstract: Objective To separate the saponins from the roots and rhizomes of Caulophyllum robustum and determine their chemical
structures. Methods The chemical constituents were isolated by repeated silica gel chromatography, medium pressure column
chromatography, and semi-preparative liquid chromatography. Their structures were elucidated by the data of NMR and MS. Results
Ten compounds were isolated from the roots and rhizomes of C. robustum and the structures of compounds 1—10 were identified as
echinocystic acid-3-O-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranoside (1), 3-O-α-L-arabinopyranosylhederagenin-28-O-β-D-

Conclusion Compound 10 is a iridoid. Compounds 1 and 10 are firstly isolated from the plants of Caulophyllum Maxim., compouds
2—9 are isolated from this plant for the first time.

红毛细辛等,可栽培。广泛分布于中国黑龙江、辽
宁、吉林、山西、甘肃和四川等地,红毛七属现有
3 种植物,分别为主产于东北亚的类叶牡丹
Caulophyllum robustum Maxim.、主产东北美的兰籽
类叶牡丹 Caulophyllum thalictroi Des (L.) Michx.
(blue cohosh)和大类叶牡丹 Caulophyllum gianteum
Maxim.,前 2种作为被民间广泛用于风湿性关节炎、
胃腹疼痛、跌打损伤及妇科疾病等的治疗。在《全
国中草药汇编》中记载该药具有理气止痛、祛风活
血的功效。《中药大辞典》描述类叶牡丹性温,味辛、
