Evans, Griffiths, and Morton (1995) described the inhibition of 5alpha-reductase and 17beta;-hydroxysteroid dehydrogenase by isoflavonoids and lignans in human genital skin fibroblast monolayers and homogenates, and in benign prostatic hyperplasia tissue homogenates. Of the lignans, ENL was the MOST POTENT INHIBITOR. All lignans tested inhibited 17beta;-hydroxysteroid dehydrogenase activity in genital skin fibroblast monolayers.
ENL = Enterolactone. il suo precursore è presente in ragione di circa 300 mg in 100g di semi di lino. ovviamente i semi andrebbero tirati con un macinasemi elettrico (alcuni sono molto efficienti).
