摘要
目的对类叶牡丹(Caulophyllum robustum)中化学成分进行分离鉴定。方法利用MCI gel柱色谱、硅胶柱色谱及制备液相色谱等方法分离纯化;通过核磁共振波谱、质谱等数据解析化合物结构。结果从类叶牡丹中分离得到10个化合物,分别鉴定为刺囊酸(1)、齐墩果酸-3-O-β-D-葡萄吡喃糖-(1→2)-α-L-阿拉伯吡喃糖苷(2)、常春藤皂苷元-3-O-β-D-吡喃葡萄糖-(1→3)-α-L-吡喃阿拉伯糖苷(3)、常春藤皂苷元-3-O-β-D-葡萄吡喃糖-(1→2)[β-D-葡萄吡喃糖-(1→3)]-α-L-阿拉伯吡喃糖苷(4)、3-O-β-D-葡萄吡喃糖-(1→2)-α-L-阿拉伯吡喃糖--28-O-刺囊酸-α-L-鼠李吡喃糖-(1→4)-β-D-葡萄吡喃糖-(1→6)-β-D-葡萄吡喃糖苷(5)、3-O-α-L-阿拉伯吡喃糖-常春藤皂苷元-28-O-(4-O-乙酰基)-α-L-鼠李吡喃糖-(1→4)-β-D-葡萄吡喃糖-(1→6)-β-D-葡萄吡喃糖苷(6)、(6R,7E,9R)-9-羟基-4,7-巨豆二烯-3-酮-9-O-β-D-葡萄糖苷(7)、(9R)-9-羟基-4,6-巨豆二烯-3-酮-9-O-β-D-葡萄糖苷(8)、麦芽糖(9)和蔗糖(10)。结论鉴定的10个化合物中,5为该植物中首次发现,其余均为首次从红毛七属植物中分离得到。
OBJECTIVE To isolate the chemical constituents from Caulophyllum robustum and confirm their chemical structures. METHODS The chemical constituents were isolated by MCI gel, repeated silica gel chromatography, preparative liquid chromatography, and their structures were elucidated by NMR and MS etc. RESULTS The structures of compounds 1 - 10 were identified as echinocystic acid ( 1 ) , oleanolic acid-3-O-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranoside ( 2 ) , hederagenin-3-O-β-D-glucopyranosyl-(1→3)-α-L-arabinopyranoside ( 3 ), hederagenin-3-O-β-D-glucopyranosyl-(1→2)[β-D-glucopyranosyl-(1→3)]-α-L-arabinopyranoside ( 4 ) , 3-O-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranosyl echinocystic acid-28-O-a-L-rham- nopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl ester (5)、3-O-α-L-arabinopyranosyl hederagenin-28-O-(4-O-acetyl)-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl ester ( 6 ), ( 6R, 7E, 9R) -9-hy- droxy-4, 7-megastigmadien-3-one-9-O-fl-D-glucoside ( 7 ) , ( 9R )-9-hydroxy-4, 6-megastigmadien-3-one-9-O-β-D-glucoside (8) , maltose (9) , and sucrose (10). CONCLUSION Compounds 1 -10 are firstly isolated from the genus Caulophyllum except 5.
