Abstract

|
|
|
Leguminosae plants are known for its phytoestrogen constituents which play a major role in the prevention of osteoporosis, cancer and heart disease. In this study, the estrogenic activity of 158 samples from 58 species, 3 subspecies and 10 varieties of Leguminosae plants growing in Korea was evaluated. An estrogen, 17β-estradiol was used as a reference compound, and the potency of each sample was expressed in relative efficacy (%) compared to that of the reference by a reporter gene assay using MCF-7 cells. As results, the estrogenic activity of methanolic extracts of Phaseolus vulgaris var. humilis, Sophora flavescens, Lespedeza × robusta, Indigofera pseudotinctoria, Maackia amurensis, Glycine soja, Wisteria floribunda, Robinia pseudoacacia, Astragalus sinicus, Pueraria lobata, Lespedeza maximowiczii var. tomentella, Trifolium repens and Crotalaria sessiliflora showed similar to or higher at 100 μg/ml than the positive control at 10 nM. These findings can be a potential evidence for developing estrogen alternatives resolving various types of menopause symptoms with information on proper harvest season and usage plant part. To the best of our knowledge, the estrogenic activity of Lespedeza × robusta, Indigofera pseudotinctoria, Wisteria floribunda, Robinia pseudoacacia and Lespedeza maximowiczii var. tomentella is reported for the first time in this study.
