Estrogenic and antioxidant activities of ethanol extracts of 45 edible and medicinal plants were evaluated by assay, and DPPH radical scavenging assay, and TBARS inhibition rate, respectively. Total polyphenol contents were in the range of 8.6 (Panax notoginseng Buck F.H. Chen.)-594.7 (Amomum globosum Loureiro) mg/g. Direct correlation between the DPPH radical scavenging activity and polyphenol content was established through simple regression analysis, whereas no correlation was observed between TBARS inhibition rate or activity and polyphenol content. Among medicinal plants screened, Glycyrrhiza glabra L. and Rheum undulatum L. showed strong antioxidant and estrogenic activities. Results of this study could be used as fundamental data for selecting potential phytoestrogen candidates.
