title: Nordihydroguaiaretic acid autoxidation produces a schisandrin-like dibenzocyclooctadiene lignan.
abstract: The lignan meso-nordihydroguaiaretic acid is known to undergo spontaneous oxidation in alkaline solution. In the presence of the trapping agent glutathione, the major oxidation products are consistent with the formation of a meso-nordihydroguaiaretic acid ortho-quinone. In the absence of a trapping agent however, the major oxidation product of meso-nordihydroguaiaretic acid in aqueous solution is a unique, stable schisandrin-like dibenzocyclooctadiene lignan that may be responsible for some of the biological effects of nordihydroguaiaretic acid.
