详细

Extract of Maackia amurensis containing genistein and resveratrol demonstrated competitive specific binding to estradiol receptors with more affinity for ERβ (average RBA = 6.25%) than for ERα (average RBA = 0.67%) in tests with experimental animals and clinical materials (endometrium biopsy). Associated flavonoids in the extract bound insignificantly to ERs although they could have a potentiating effect in the whole extract. Therefore, M. amurensis extract contained various phytoestrogens that determined the therapeutic potential (effect on cell growth, inflammation, apoptosis, angiogenesis, carbohydrate and lipid metabolism).
