Abstract： 目的对黄精Polygonatun sibiricum根茎中的化学成分进行系统研究.方法利用各种柱色谱及薄层制备色谱技术进行分离纯化,并根据理化性质及波谱(IR,UV,1HNMR,13CNMR,ESIMS,FAB-MS)分析鉴定其化学结果.结果从黄精干燥根茎中得到6个化合物和1组混合物,分别鉴定为:(+)一syringaresinol(Ⅰ),(+)-syringaresinol-O-β-D-吡喃葡萄糖苷(Ⅱ),liriodendrin(Ⅲ)和(十)-pinoresinol-O-β-D-吡喃葡萄糖基(1→6)-β-D-吡喃葡萄糖苷(Ⅳ),正丁基-p-D-吡喃果糖苷(Ⅴ),4′,5,7-三羟基-6,8-二甲基高异黄酮(Ⅵ)和黄精神经鞘苷A,B,C(Ⅲ).结论首次从该属植物中分离得到了木脂素类成分,化合物Ⅰ,Ⅲ,Ⅲ,Ⅳ,Ⅶ均为首次从该属植物中分得,Ⅴ和Ⅵ为首次从该种植物中分得.
