Abstract

The transgenic Arabidopsis plant system, pER8-GFP, may be used as a powerful tool in searching for natural estrogen-agonists/antagonists. Among selected plant extracts and natural products, the method was able to distinguish active extracts (e.g., Glycine max and Pueraria lobata) and pure compounds (e.g., 17beta-estradiol (1), genistein (10), and daidzein (11)) and also to distinguish effects of structural changes on activity. Thus, this rapid sensitive system was proven to be suitable for the discovery of natural products with estrogenic activity.
