Beschreibung

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.

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.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
