Coleus species have diverse ethnobotanical uses, most of them related to their medicinal properties. Previously, we described the antiproliferative effect of the ethanolic extract of Coleus neochilus (also known as boldo rastrero). This study focused on the effect of one of the subfractions of the ethanolic extract, the ethyl acetate fraction (BRAE), on human breast cancer cells. Four different fractions were obtained from the original ethanolic extract by using different solvents: hexane, chloroform, ethyl acetate and methanol-water. Incubation with BRAE 25 μg/ml reduced cell viability in MCF-7, T47-D, and MDA-MB-231 tumor cells (35%, 21% and 8% reduction, respectively; p
