title: Deuterated phytoestrogen flavonoids and isoflavonoids for quantitation.
abstract: Isotopically and isomerically pure polydeuterated flavonoids and isoflavonoids have been prepared for quantitation of these compounds in biological matrices. Various deutero-labeling techniques are presented and methods for establishing the isotopical and isomerical purity of deuterated products are discussed.
