Seasonal Fluctuations of Plastochromanol‐8 and α‐Tocopherol Amounts in the Leaves of Cecropia Trees

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Plastochromanol‐8 (PC‐8) is a homologue of γ‐tocotrienol with a longer side chain (eight instead of three isoprene units) and therefore also a representative of the tocochromanol (vitamin E) group. PC‐8 has been determined in various plants and seeds, with Cecropia sp. leaves showing unusually high levels.
