“…M-5 ϳ M-13 were identified as irisolidone, tectorigenin, tectoridin, 5,7-dihydroxy-8,4Ј-dimethoxyisoflavone, isotectorigenin, biochanin A, genistein, daidzein, and equol, respectively, by comparing their UV, NMR, MS, or CD data (Tables 2) with the reported values (Bashir et al, 1991;Yasuda et al, 1994;Yasuda and Ohsawa, 1998;Talukdar et al, 2000;Yin et al, 2006;Moriyasu et al, 2007;. M-6 ϳ M-13 were first isolated as the metabolites of kakkalide.…”

ABSTRACT:Kakkalide is a major isoflavonoid from the flowers of Pueraria lobata (Willd.) Ohwi, possessing the protective effect against ethanol-induced intoxication and hepatic injury. The metabolism of kakkalide was investigated in rats. Thirteen metabolites were isolated by using solvent extraction and repeated chromatographic methods and identified by using spectroscopic methods including UV, IR, mass spectrometry, NMR, and circular dichroism experiments.

“…For example, identification of glaziovianin A in Ateleia glazioviana [11] belongs to the most recent discoveries. New isoflavones were also identified in rhizomes of Belamcanda chinensis [12] or new prenylisoflavone derivatives were discovered in roots of Hedysarum scoparium [13]. Isolation of new isoflavones also influences research in biomedicine and pharmacochemical sciences.…”

Isoflavones are natural substances which elicit a number of physiological effects in living organisms. The substances are synthesized in plant tissues as protective agents against biotic stress (i. e. bacterial infection). Isoflavones are also an important dietary constituent in human nutrition. Modern trends in studies of isoflavones in plant materials and foodstuffs and procedures for chemical analyses of isoflavones in human body fluids and plant tissues are discussed in this review. Highly effective extraction and purification techniques, i. e. solid-phase extraction, accelerated-solvent extraction, and Soxhlet extraction, are presented. Latest procedures in chromatographic separation of isoflavones that apply different types of sorbents are described. Immunochemical analysis, electrochemical sensing of isoflavones, and spectrometric and other analytical techniques and their applications are also mentioned. Special attention is paid to the highly selective and sensitive technique of mass spectrometry and its application for identification of isoflavones and their glucosides in plants. Studies of interactions of isoflavones with cell receptors and a number of biologically active substances such as DNA and proteins are described. The review does not intend to give a complete overview of the topics considered but rather to present modern and most recent methods used in studies of isoflavones.
