Description

General description

Genistin belongs to the class of isoflavone glycosides generally extracted from soybeans.

Application

Genistin has been used as an analytical reference standard for the analysis of genistin in:

• Legumes by ultra-high performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS) with electrospray ionization (ESI) source and multiple reaction monitoring (MRM) detection.

It may be used as an analytical reference standard for the determination of genistin in:

• Soy-based foods and dietary supplements by LC coupled to absorbance detection and isotope-dilution mass spectrometry (IDMS), equipped with ESI source and selected ion monitoring (SIM) mode.
• Soy products by colloidal gold-based indirect competitive immunochromatographic assay (ICA).
• Rainbow trout muscle by QuEChERS (quick, easy, cheap, effective, rugged and safe) extraction and LC-ESI-MS/MS.
• Soybean flour by matrix solid phase dispersion extraction (MSPD) and LC with ultraviolet-diode array detection (UV-DAD).
• Soymilk samples by HPLC-UV operating under the gradient elution mode.
