[摘要]:The lignan meso-nordihydroguaiarctic 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 mesonordihydroguaiaretic 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. |
