太白楤木根皮的齐墩果酸皂甙

OLEANOLIC ACID SAPONINS FROM THE ROOT BARK OF ARALIA TAIBAIENSIS

    摘要
  • 摘要: 从太白楤木(Aralia taibaiensis Z.Z.Wang et H.C.Zheng)根皮中首次分离到5个齐墩果酸皂甙,根据理化性质和光谱数据,分别鉴定为木皂甙A(1),3-O-α-L-呋喃阿拉伯糖(1→4)-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(2),3-O-α-L-呋喃阿拉伯糖(1→4)-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),屏边三七甙R2(4)和3-O-｛β-D-吡喃葡萄糖(1→3)α-L-呋喃阿拉伯糖(1→4)-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(5)。2,3和5为新化合物,分别命名为太白楤木皂甙I(taibaienoside I)、太白楤木皂甙II(taibaienoside II)和太白楤木皂甙III(taibaienoside III)。

     

    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-α-L-arabinofuranosyl(1→4)6′-O-n-butyl-β-D-glucuronopyranosyl-oleanolic acid-28-O-β-D-glucopyranoside (2), 3-O-α-L-arabinofuranosyl(1→4)-6′-O-ethyl-β-D-glucuronopyra-nosyl-oleanolic acid-28-O-β-D-glucopyranoside (3), stipuleanoside R2 (4) and 3-O-β-D-glucopyranosyl(1→3)α-L-arabinofuranosyl(1→4)-6′-O-ethyl-β-D-glucuronopyranosyl-oleanolic acid-28-O-β-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.
