摘要
黄毛木(AraliadecaisneanaHance)为五加科木属植物。从其根的甲醇提取物中分离得到一个皂甙化合物(I),根据光谱(IR,1HNMR,13CNMR,MS,Longrange1H-1HCOSY和1H-13cHETCOR)解析和化学反应(酸水解,乙酰化和碱水解)证明,化合物1的结构确定为3-O-[β-D-吡喃木糖1→3)]-β-D-吡喃葡萄糖(1→2)-β-D-吡喃葡萄糖-28-O-β-D-吡喃葡萄糖(1→6)-β-D-吡喃葡萄糖酯甙。该化合物是一个新的三萜皂甙,命名为黄毛木皂甙A(aradecosideA)。
A new triterpenoid
saponin,C59H96O27 ,named Aradecoside A(I),was isolatedfrom the root
of Aralia decaisneana Hance(Araliaceae).The determination of its
structure was based onspectroscopic analysis( IR, 1HNMR,13CNMR
,MS,Long-range 1H-1HCOSY or1H-13C HETCOR)of the natural compound and
its derivatives,and characterized as 3-O-[β-D-xylo-pyranosyl(1→3)]-
β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl-oleanolic acid-28-O-β
-D-glucopyranosyl(1→6)-β-D-glucoDyrandsyl ester.
