摘要/Abstract

摘要： 从太白楤木(Aralia taibaiensis Z. Z. Wang et H. C. Zheng)根皮中首次分离得到四个三萜皂甙, 根据理化性质和光谱数据, 分别鉴定为齐墩果酸-3-O-[β-D-吡喃木糖(1→2)][β-D-吡喃葡萄糖(1→3)]-β-D-吡喃葡萄糖醛酸甙(1), tarasaponin V(2), 3-O-{[β-D-吡喃木糖(1→2)][β-D-吡喃葡萄糖(1→3)]-β-D-吡喃葡萄糖醛酸乙酯}-齐墩果酸-28-O-β-D-吡喃葡萄糖甙(3)和3-O-{[β-D-吡喃木糖(1→2)][β-D-吡喃葡萄糖(1→3)]-β-D-吡喃葡萄糖醛酸丁酯}-齐墩果酸-28-O-β-D-吡喃葡萄糖甙(4)。1为新天然产物, 3和4为新化合物, 分别命名为太白楤木皂甙VI (taibaienoside VI)、太白楤木皂甙 VII (taibaienoside VII)和太白楤木皂甙 VIII (taibaienoside VIII)。

Abstract: Four triterpenoid saponins were isolated from the root bark of Aralia taibaiensis Z.Z.Wang et H.C.Zheng. On the basis of their chemical properties and spectral data, they were identified as oleanolic acid-3-O-[β-D-xylopyranosyl (1→2) ][β-D-glucopyranosyl (1→3)]-β-D-glu-curonopyranoside (1), tarasaponin V (2), 3-O-{[ β-D-xylopyranosyl (1→2)][β-D-glucopyranosyl (1→3) ]-6'-O-ethyl-β-D-glucuronopyranosyl}-oleanolic acid-28-O-β-D-glucopyranoside (3) and 3-O-{[β-D-xylopyranosyl (1→2) ] [β-D-glucopyranosyl (1→3) ]-6'-O-n-βutyl-β-D-glucuronopyrano-syl}-oleanolic acid-28-O-β-D-glucopyranoside (4). Compound 1 is a new natural product named taibaienoside VI. Compound 2 was isolated from the title plant for the first time. Compounds 3 and 4 are new compounds and named taibaienoside VII and taibaienoside VIII, respectively.

Key words: Aralia taibaiensis, Araliaceae, Taibaienoside VI, Taibaienoside VII, Taibaienoside VIII
