Abstract
Novel inhibitors of the enzyme action of lipoxygenase, especially 5-lipoxygenase and 12-lipoxygenase that are derived from the extraction of the seeds of the perilla (crispa) or perilla (frutescens) plant. These inhibitors are suitably extracted from these seeds using alcohol, preferably ethanol, to form an extract or more preferably to further extract the alcoholic extract with ethyl acetate and water to partition the active inhibitors to the ethyl acetate. The particularly preferred inhibitors are luteolin and chrysoeriol.
