Isoflavones are a subject of study due to their great bioactive properties in human health, within this group is biochanin A, which behaves as a unique phytoestrogen due to its estrogenic conformation similar to these; but also, because it shows cardiovascular protection due to its hypocholesterolemic effects. The objective of the study was to isolate nd characterize the isoflavone from the heartwood of Swartzia simplex from a sample of this species that is phylogenetically related to S. polyphylla collected at the "El Huayo" Arboretum of the Faculty of Forestry Engineering of the UNAP, located between the Zungarococha and Nina Rumi hamlets, District of San Juan Bautista, Province of Maynas, Loreto Region. The purified product was identified and characterized by determining its physicochemical and UV-visible spectrometric parameters. The results were as follows: Melting point 216 °C, Rf...
