Application

Daidzein was used as standard in determination of daidzein and genistein, in soybean food using in-tube solid-phase microextraction coupled to high-performance liquid chromatography (in-tube SPME–HPLC). It was also used as reference standard in determination of isoflavones in red clover using high-performance liquid chromatography–UV–electrospray ionization-mass spectrometric detector (HPLC–UV–ESI-MSD).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Biochem/physiol Actions

Soy isoflavone daidzein protects against oxidative damage in liver cells induced by 7,12-dimethylbenz[a]anthracene (DMBA). Catalase and superoxide dismutase activity, down-regulated by DMBA, was restored by daidzein.

General description

Daidzein is an endocrine-active estrogenic isoflavone. This phytoestrogen is capable to bind to estrogen to exert estrogenic effects in vivo. It can naturally be found in soybean seed and flour.

Packaging
