Application


  • Phytoestrogens in Fish Feed Production:Coumestrolis is used as a biomarkers in fish feed production, facilitating the assessment of plant raw materials used in these feeds (Pavlopoulos et al., 2023).

  • Coumestrol and Soybean Leaf Senescence: Coumestrol′s role in soybean leaf senescence is explored, particularly its interactions with phytohormones, suggesting potential agronomic benefits and applications in crop science, it acts as a phytoalexin (Mun et al., 2021).

  • Systemic Defense in Soybeans: Investigating the effects of priming with coumestrol on soybean defense against the root-lesion nematode, this research highlights its potential as a natural plant defense enhancer (Adss et al., 2021).

Biochem/physiol Actions

Coumestrol has anti-estrogenic actions in the brain and pituitary, mediated through estrogen receptor-α.
