“…Many factors affect the content of phytoestrogens including genetic factors (plant genotype), environmental conditions (temperature, rainfall, humidity, sunlight), biotic factors (fungal diseases), stages of maturity (early vegetative-late flower), stand age of alfalfa, plant parts (leaves, stems and flowers), management strategies (cutting frequency), and preservation method [16,26,33,34]. Conducted studies and currently available data on quantification of the phytoestrogen content in alfalfa show that their amount is highly variable and results are very often inconsistent [35,36]. Martin et al [37] found that the highest average content of coumestrol was 99 µg g −1 of DM, followed by formononetin, daidzein, biochanin A, and genistein with 43, 21, 19, and 14 µg g −1 of DM, respectively.…”
