摘　　要：从虎刺楤木［Ａｒａｌｉａ ａｒｍ ａｔａ （Ｗａｌｌ．） Ｓｅｅｍ ．］根皮中分离到１１个成分，根据理化及光谱性质，鉴定其中７个为皂甙，即去葡萄糖竹节参皂甙Ⅳａ（ＡＴ－Ⅰ）、竹节参皂甙Ⅳａ（ＡＴ－Ⅱ）、姜状三七甙Ｒ１（ＡＴ－Ⅲ）、人参皂甙Ｒ０（ＡＴ－Ⅳ）、Ａｄ－Ⅲ［（ＡＴ－Ⅴ）后称黄毛楤木皂甙］、虎刺楤木皂甙（ＡＴ－Ⅵ）和楤木皂甙Ａ（ＡＴ－Ⅶ），其余４个成分则为二十八羧酸（ＡＴ－Ⅷ）、谷甾醇（ＡＴ－Ⅸ）、谷甾醇与豆甾醇的混合物（ＡＴ－Ⅹ）及齐墩果酸（ＡＴ－Ⅺ）。以上成分均系首次从该植物中分得。Eleven constituents were isolated from root bark of Aralia armata (Wall.) Seem.Their structures were elucidated by spectra (IR, MS, 1H NMR and 13 C NMR) and chemical analyses.They were deglucose chikusetsusaponin Ⅳa (AT Ⅰ), chikusetsusaponin Ⅳa (AT Ⅱ), zingibroside R 1 (AT Ⅲ), ginsenin R 0 (AT Ⅳ), decaisneanaside (AT Ⅴ), armatoside (AT Ⅵ), araloside A (AT Ⅶ), octacosanoic acid (AT Ⅷ), β sitosterol (AT Ⅸ), mixture of β sitosterol and stigmastterol (AT Ⅹ), oleanolic acid (AT Ⅺ). They were for the first time found in this plant, AT Ⅵ is a new saponin.
