Antioxidant phenylpropanoid glycosides from the leaves of Wasabia japonica

Phytochemistry. 2008 Feb;69(3):827-32. doi: 10.1016/j.phytochem.2007.08.021. Epub 2007 Oct 24.

Abstract

From the MeOH extract of the leaves of W. japonica, seven phenylpropanoid gentiobiosides (1-7) were isolated along with eight known phenylpropanoids (8-15). Structures of 1-7 were determined based on spectroscopic data and chemical evidence. The activity of compounds 1-15 to scavenge superoxide anion radicals was investigated using an electron spin resonance (ESR) method.
