Abstract

Five oleanolic acid saponins were isolated from the root bark of Aralia taibaiensis Z.Z. Wang et H.C. Zheng. By spectroscopic and chemical methods, they were identified as araloside A (1), 3-O-[alpha-L-arabinofuranosyl(1-->4)-6'-O-n-butyl-beta-D- glucuronopyranosyl]-oleanolic acid-28-O-beta-D-glucopyranoside (2), 3-O-[alpha-L-arabinofuranosyl(1-->4)-6'-O-ethyl-beta-D- glucuronopyra-nosyl]-oleanolic acid-28-O-beta-D-glucopyranoside (3), stipuleanoside R2(4) and 3-O-(beta-D-glucopyranosyl(1-->3) [alpha-L-arabinofuranosyl(1-->4)]-6'-O-ethyl-beta-D- glucuronopyranosyl)-oleanolic acid-28-O-beta-D-glucopyranoside (5). Saponin 1 and 4 were isolated from the title plant for the first time. 2, 3 and 5 are new compounds and named taibaienoside I, taibaienoside II and taibaienoside III, respectively.

摘要

从太白楤木（Aralia taibaiensis Z.Z. Wang et H.C. Zheng）的根皮中分离得到了五种齐墩果酸皂苷。通过光谱和化学方法，它们被鉴定为楤木皂苷A（1）、3 - O - [α - L -阿拉伯呋喃糖基（1→4）- 6'- O -正丁基 -β - D -葡萄糖醛酸吡喃糖基] -齐墩果酸 - 28 - O -β - D -葡萄糖吡喃糖苷（2）、3 - O - [α - L -阿拉伯呋喃糖基（1→4）- 6'- O -乙基 -β - D -葡萄糖醛酸吡喃糖基] -齐墩果酸 - 28 - O -β - D -葡萄糖吡喃糖苷（3）、刺囊酸皂苷R2（4）和3 - O -（β - D -葡萄糖吡喃糖基（1→3）[α - L -阿拉伯呋喃糖基（1→4）] - 6'- O -乙基 -β - D -葡萄糖醛酸吡喃糖基）-齐墩果酸 - 28 - O -β - D -葡萄糖吡喃糖苷（5）。皂苷1和4首次从该植物中分离得到。2、3和5是新化合物，分别命名为太白皂苷I、太白皂苷II和太白皂苷III。
