In this study, sahandone (1) and a new diterpenoid named sahandol II (2) were isolated from the roots of Salvia chloroleuca Rech. f. & Aellen, Lamiaceae. The absolute configurations of compounds 1 and 2 were assigned by comparison of experimental electronic circular dichroism spectra and comparing with published data. Cytotoxic and apoptotic evaluation of the isolated compounds and the methanol crude extract and its subfractions including petroleum ether, dichloromethane, ethyl acetate, n-butanol and aqueous fraction on two human prostate cancer cell lines and a breast cancer cell lines, showed that non-polar and semi-polar subfractions had the potent cytotoxic effect on PC3 cells with the IC50 values of 24.19, 33.59, and 47.15 mu g/ml, respectively. Sub-G1 peak in flow cytometry histogram of cells treated with petroleum ether, dichloromethane and ethyl acetate subfractions showed the induction of apoptosis. Change in the Bax/Bcl-2 ratio and cleavage of poly ADP-ribose polymerase were observed. (C) 2019 Sociedade Brasileira de Farmacognosia. Published by Elsevier Editora Ltda.
