摘　　要：从黄毛楤木(Aralia decaisneana Hance)根皮分得3种皂甙(Ad-Ⅰ、Ad-Ⅱ、Ad-Ⅲ)和1种由 Ad-Ⅲ水解得到的次级甙(Ad-Ⅳ),经光谱(IR、FAB-MS、~1H-NMR、^(13)C-NMR)和化学分析(酸、碱水解法),分别鉴定为楤木皂甙 A、3-O-[α-L-阿拉伯呋哺糖-(1→4)-β-D-葡萄吡喃糖醛酸]-齐墩果酸甙、3-O-[β-D-半乳吡喃糖-(1→4)-β-D-半乳吡喃糖-(1→3)-β-D-葡萄吡喃糖醛酸]-齐墩果酸-28-O-β-D-葡萄吡喃糖甙、3-O-[-β-D-半乳吡喃糖-(1→4)-β-D-半乳吡喃糖-(1→3)-β-D-葡萄吡喃糖醛酸]-齐墩果酸甙。前两种皂甙系首次从该植物分得,后两种为新化合物。Three saponins(Ad-Ⅰ,Ad-Ⅱ,Ad-Ⅲ)were isolated from root bark of Aralia decaisneana Hance,and a prosapogenin Ad-Ⅳ was obtained from hydrolysis of Ad-Ⅲ.Their structures were elucidated by spectra(IR,FAB-MS,~1H-NMR,^(13)C- NMR)and chemical analyses(acid and base hydrolysis),they were araloside A(Ad-Ⅰ),3-O-[α-L-arabinofuranosyl-(1→-4)-β-D-glucuronopyranosyl-]-oleanolic acid(Ad-Ⅱ),3-O-[β-D-galactopyranosyl-(1→4)-β-D-galactopyranosyl-(1→3)-β- D-glucuronopyranosyl-]-oleanolic acid-28-O-β-D-glucopyranoside(Ad-Ⅲ),3-O- [-β-D-galactopyranosyl-(1→4)-β-D-galactopyranosyl-(1→3)-β-D-glucuro nopyrano- syl-]-oleanlic acid(Ad-Ⅳ).Ad-Ⅰ and Ⅱ are for the first time found in this Plant,Ad-Ⅲ and Ⅳ are new compounds.
