Introduction: Boldoa purpuracens Cav. is a plant belonging to Nyctaginaceae family used in Cuba and other Latin America regions as diuretic. Phytochemical analysis has shown the presence of biologically active compounds such as flavonoids and triterpenic saponins in the plant. The aim of the present investigation was to evaluate the antiproliferative potential of a fraction of saponins isolated from stem of the species in H-460 and H-125 human lung cancer cells and PC-3 human prostate carcinoma grade IV. Methods: Dried and pulverized stem bark (1.2 kg) of Boldoa purpurascens were defatted and subsequently extracted with 80% ethanol. Ethanol extract was evaporated and extracted with water-saturated n-BuOH (crude of saponins). The crude was applied onto the Sephadex LH-20 column, using a mixture of chloroform/methanol/water (100: 10: 0 to 100: 100: 1) to get the fractions. Fraction 2 was used for the antiproliferative assay. PC 3 (7, 5 x 104 cells/mL), H 460 (1 x 104 cells/mL), H 125 (1 x 104 cells/mL) and MCR5 (7.5 x 104 cells/mL) cells were seeded in 96-well plates. Concentrations of 100, 10, 0.1, 0.01 and 0.001 µg/mL of F2 were used and Quillaja saponaria, paclitaxel and cisplatin were used as standards. Absorbance was measured at 562 nm. Results: The high cell density assay showed IC50 values of 23.05, 133.99 and 13.06 µg/mL for PC-3, H-460 and H-125 tumor cancer cells, respectively. Conclution: the fraction of saponins isolated from stem bark of Boldoa purpurascens showed a potent antiproliferative effect.
