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) and one secondary Ad-IV (Ad-IV) hydrolyzed by Ad-III were obtained from the bark of Aralia decaisneana Hance. IR, FAB-MS, ~1H-NMR, ~(13)C-NMR) and chemical analysis (acid, alkali hydrolysis method), identified as Agarwood A, 3-O-[α-L-arabinofurol, respectively Glucose-(1→4)-β-D-Glucuronanoate]-Olivine Oleanate, 3-O-[β-D-galactopyranoside-(1→4)-β-D -galactopyranoside-(1→3)-β-D-glucopyranuronic acid]-oleanolic acid-28-O-β-D-pyranopyranose, 3-O-[- β-D-galactopyranoside-(1→4)-β-D-galacto-pyranose-(1→3)-β-D-glucopyranuronic acid]-barium oleanate. The first two saponins were isolated from the plant for the first time, and the latter two were new compounds.
