Antiestrogenic and cytotoxic graph of active samples and controls. The petroleum ether extract of A. sinensis, and the dichloromethane extracts of B. vulgaris and C. americana had antiestrogenic activity without apparent cytotoxicity in the Ishikawa alkaline phosphatase inhibition assay when tested at 20 μg/mL. Samples were tested at least three independent times in triplicate. Samples were considered active if they were within one standard deviation or greater of 50% for the antiestrogenic assay. Samples with greater than 20% cytotoxicity are know to interfere with the accuracy of the antiestrogenic assay by causing a false positive result.
