the abstract from http://www.ncbi.nlm.nih.gov/pubmed/14706564 says "GBE contains 24% of phytoestrogens, which is kaempferol, quercetin, and isorhamnetin." and that Ginkgo works more on ER-beta, than ER-alpha. ER-alpha is present in breast tissue, instead of ER-beta. The three chemicals can be looked up too at that website, but a good one was behind a paywall, and its abstract said very little about the results.
