摘要: 从石岩枫Mallotus repandus (willd) muell.arg.全草中分离得到两个新的木脂素类化合物,根据理化性质和波谱鉴定其化学结构,分别为:repandusin(1)、repanduthylin(2)。化合物1 对H2O2诱导的PC12细胞损伤有一定的保护作用,化合物2 对H2O2诱导的PC12细胞损伤有微弱的保护作用。

关键词: 石岩枫, 木脂素类, H2O2诱导, PC12细胞

Abstract: Two new coumarinolignoids were isolated from the Rhizome of Mallotus repandus (willd) Muell. Arg.Silica gel and Sephadex LH-20 column chromatographies were used to isolate the chemical constituents,and spectroscopic techniques were employed to elucidate their structures.Their structures were identified as repandusin (1) and repanduthylin (2). Compound 1 and 2 had medium and feeble protective effects to scathing PC12 cells which was induced by H2O2, respectively.

Key words: Mallotus repandus, coumarinolignoids, H2O2-induction, PC12 cells
