Abstract

Five new oleanolic acid glycosides, tarasaponins III-VII, were isolated from the dried root-bark of Aralia elata together with stipuleanoside R2, in addition to eight saponins previously reported. They were characterized as oleanolic acid 3-O-[beta-D-xylopyranosyl(1-->2)] [beta-D-glucopyranosyl(1-->3)]-alpha-L-arabinopyranoside, beta-D-glucopyranosyl oleanolate 3-O-[beta-D-glucopyranosyl(1-->2)][alpha-L-arabinofuranosyl (1-->4)]-beta-D-glucuronopyranoside, beta-D-glucopyranosyl oleanolate 3-O-[beta-D-xylopyranosyl(1-->2)][beta-D-galactopyranosyl (1-->3)]-beta-D-glucuronopyranoside, beta-D-glucopyranosyl oleanolate 3-O-[beta-D-xylopyranosyl(1-->2)][beta-D-glucopyranosyl (1-->3)-alpha-L-arabinopyranoside, respectively.

摘要

从辽东楤木干燥根皮中分离出5种新的齐墩果酸糖苷（塔拉皂苷III-VII）以及托叶皂苷R2，此外还有之前报道的8种皂苷。它们分别被鉴定为齐墩果酸3-O-[β-D-吡喃木糖基(1→2)][β-D-吡喃葡萄糖基(1→3)]-α-L-吡喃阿拉伯糖苷、β-D-吡喃葡萄糖基齐墩果酸酯3-O-[β-D-吡喃葡萄糖基(1→2)][α-L-呋喃阿拉伯糖基(1→4)]-β-D-吡喃葡萄糖醛酸苷、β-D-吡喃葡萄糖基齐墩果酸酯3-O-[β-D-吡喃木糖基(1→2)][β-D-吡喃半乳糖基(1→3)]-β-D-吡喃葡萄糖醛酸苷、β-D-吡喃葡萄糖基齐墩果酸酯3-O-[β-D-吡喃木糖基(1→2)][β-D-吡喃葡萄糖基(1→3)]-α-L-吡喃阿拉伯糖苷。
