Although some studies have evaluated the cytotoxic activity of different Fabaceae species, there has been only limited research into the cytotoxic effect of Dorycnium pentaphyllum. The purpose of this study was to determine the antioxidant properties and cytotoxic effect of D. pentaphyllum extract on various human cancer cells. The total phenolic content (TPC) of the extract was determined using colorimetric method. The cytotoxic effect of the extract on human lung (A549), liver (HepG2), and breast (MCF-7) cancer cells and a normal human fibroblast cells was assessed using the MTT assay. TPC value of extract was found as 140.3 +/- 1.1 mg gallic acid equivalent per g sample. Extract showed selective cytotoxicity on all studied cancer cells compared to normal fibroblast cells, and the IC50 values of the extract in the cancer cells range from 100.4 to 298.5 mu g/mL. This is the first study to reveal the cytotoxic effect of D. pentaphyllum extract on cancer cell lines. Phytomedical applications of D. pentaphyllum may represent promising approaches in the treatment of cancer.

The purpose of this study was to investigate the phytochemical analysis of D. pentaphyllum and its cytotoxic activity on human cervical cancer (HeLa) cells with possible mechanisms. Total phenolic contents (TPC) and phytochemical analysis of the extract were evaluated using spectrophotometric method and RP-HPLC, respectively. The cytotoxic effect of the extract was evaluated using the MTT assay. The mechanism of the cytotoxic effect of the extract was also evaluated in terms of apoptosis, cell cycle, and mitochondrial membrane potential (MMP) using the fluorometric methods. The TPC of the extract was calculated as 68.9 +/- 2.3 mg gallic acid equivalent per g sample and quercetin was determined as the major phenolic in the extract. The extract showed a selective cytotoxic effect (6.5-fold) on HeLa cells compared to normal fibroblast cells. The cytotoxic effect of the extract was found to be due to the arresting of the cell cycle in the S phase and increasing apoptosis through decreased MMP. Further studies are needed for the comprehensive effects of the extract on cell signaling.
