Ethanol Extract of Securidaca longipedunculata Induces Apoptosis in Brain Tumor (U87) Cells

Incidence of cancer is estimated to be on the increase and current anticancer drugs are characterized by narrow margin of safety and side effects. There is the need to explore new drugs especially from plants since plants serve as major source of drugs. Securidaca longipedunculata Fresen plant is called the mother of all medicines in northern Nigeria and is used traditionally in the treatment of cancers by most traditional medicine practitioners in the region. This study is aimed at evaluating the anticancer activity of the plant extract using U87 brain tumor cell line. Ethanol extract of its root bark was prepared and fractionated by silica gel column chromatography. In vitro activity of the extract and fractions were assessed on the viability of U87 malignant brain tumor cell line by using hemacytometer, annexin V-PE and 7AAD flow cytometry and western blot detection of Poly-ADP-Ribose-Polymerase (PARP) cleavage. The results showed that the extract significantly (p
