This present study was performed to investigate estrogenic activity of Korean edible wild plants for alternative of estrogen replacement therapy in postmenopausal women. When the estrogenic activity was measured by estrogen induced proliferation of MCF-7 cells, of investigated 29 extracts, 3 samples of kudzu vine (Pueraria thunbergiana), Cardamine leucantha, and David Vetchling (Lathyrus davidii) exhibited a significant proliferation of above 20% at concentration of 100 ${mu}g/mL$. This stimulation of MCF-7 cell proliferation could be completely blocked by addition of estrogen antagonist ICI 182,780 (100 nM), indicating estrogen receptor-dependent mechanism of these estrogenic effects on MCF-7 cell proliferation.
