Isoflavones, polyphenolic compounds, from plants belonging to the Fabaceae family act as phytoestrogens and possess a pseudo-hormonal effect by binding with estrogen receptors in the human body. Due to this property, isoflavones exhibit multiple health-promoting benefits. In the class of isoflavones, biochanin A and biochanin B (formononetin) are prominent compounds renowned for their wide therapeutic window against numerous pathological conditions. Biochanin A and B possess antidiabetic, antiobesity, hepatoprotective, anticancer, and antiinflammatory activities. Biochanin A and B are rapidly absorbed in the body and possess safe pharmacokinetics as indicated by several in vivo investigations. This chapter aims to elaborate on the natural sources, pharmacological potential as well as bioavailability and pharmacokinetics of biochanin A and B, suggesting these compounds as interesting and safe candidates for drug design and development in the near future. © 2021 Elsevier Inc.eninfo:eu-repo/semantics/closedAccessBiochanin ABiochanin BIsoflavonesPharmacological activitiesPhytoestrogensBook Chapter56358810.1016/B978-0-12-822923-1.00031-52-s2.0-85127701437N/A
