A new triterpenoid saponin, together with five known saponins, were isolated from the nonpolar n-hexane fraction of the leaves of Aralia elata. The structure of the new saponin, durupcoside C, was elucidated as hederagenin 3-O-beta-D-glucopyranosyl(1-->3)-beta-D-glucopyranosyl(1-->3)-alpha-L-arabinopyranoside on the basis of spectroscopic analysis. The known saponins were characterized as 3-O-alpha-L-rhamnopyranosyl(1-->2)-alpha-L-arabinopyranosyl hederagenin 28-O-beta-D-xylopyranosyl(1-->6)-beta-D-glucopyranosyl ester, hederagenin 3-O-beta-D-glucopyranosyl(1-->3)-alpha-L-rhamnopyranosyl(1-->2)-alpha-L-arabinopyranoside, oleanolic acid 3-O-beta-D-glucopyranosyl(1-->3)-alpha-L-rhamnopyranosyl(1-->2)-alpha-L-arabinopyranoside, hederagenin 3-O-alpha-L-rhamnopyranosyl(1-->2)-alpha-L-arabinopyranoside (alpha-hederin), and hederagenin 3-O-beta-D-glucopyranosyl(1-->3)-alpha-L-arabinopyranoside (collinsonidin). In addition, two known lipids, Arisaema glyceride 3 and ceramide mixtures were also isolated and characterized. Collinsonidin and two known lipids were isolated for the first time from this plant.
从辽东楤木叶的非极性正己烷馏分中分离出一种新的三萜皂苷以及五种已知皂苷。通过光谱分析，将新皂苷durupcoside C的结构鉴定为常春藤皂苷元3 - O - β - D - 吡喃葡萄糖基(1→3)-β - D - 吡喃葡萄糖基(1→3)-α - L - 阿拉伯吡喃糖苷。已知皂苷分别鉴定为3 - O - α - L - 鼠李吡喃糖基(1→2)-α - L - 阿拉伯吡喃糖基常春藤皂苷元28 - O - β - D - 吡喃木糖基(1→6)-β - D - 吡喃葡萄糖基酯、常春藤皂苷元3 - O - β - D - 吡喃葡萄糖基(1→3)-α - L - 鼠李吡喃糖基(1→2)-α - L - 阿拉伯吡喃糖苷、齐墩果酸3 - O - β - D - 吡喃葡萄糖基(1→3)-α - L - 鼠李吡喃糖基(1→2)-α - L - 阿拉伯吡喃糖苷、常春藤皂苷元3 - O - α - L - 鼠李吡喃糖基(1→2)-α - L - 阿拉伯吡喃糖苷（α - 常春藤皂苷）以及常春藤皂苷元3 - O - β - D - 吡喃葡萄糖基(1→
