Two New Coumarinolignoids from Mallotus repandus (Willd) Muell.Arg.

Abstract

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
