Nov 21, 2008 · Abstract. In the working conditions used for the extraction of iron with 1,10‐phenanthroline (o‐phe) or 2–2’ Bipyridyl (Bipy) from plant material, in vitro photoreduction of ferric ions occurs. Nevertheless, iron in plant extracts was found to be independent of the illumination conditions where the sample was maintained during the extraction.
