Application:	Formononetin has been used as a reference standard for the determination of formononetin in: • Cow, goat, sheep and human milk samples by magnetic-micro-dispersive solid-phase extraction (m-μ-dSPE) combined with ultra-high performance liquid chromatography-triple quadrupole electrospray ionization-tandem mass spectrometry (UHPLC-QqQ-ESI-MS/MS) operating under the multiple reaction monitoring (MRM) mode of detection. • Dairy products by quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction procedure and UHPLC-QqQ-ESI-MS/MS with MRM mode of detection. It may be used as a reference standard for the determination of formononetin in: • Natural products by turbulent flow chromatography liquid chromatography-high resolution mass spectrometry (TFC LC-HRMS). • Soy-drinks by gas chromatography combined with MS/MS operating on electron ionization (EI) mode. • Rat plasma by UHPLC-QqQ-ESI-MS/MS.
Biochem/physiol Actions:	Isoflavone found in red clover. Effective against Giardia lamblia infection, at least partially by inducing detachment of trophozoites from intestinal mucosa.
General description:	Formononetin belongs to the isoflavones class of polyphenols.
