Objective:To validate scientifically the traditional use of Salacia leptoclada Tul.(Celastraceae)(***)and to isolate and elucidate the structure of the biologically active ***:Bioassay-guided fractionation of the acetonic extract of the stem barks of *** was carried out by a combination of chromatography technique and biological experiments in viro using Plasmodium falciparum and P388 leukemia cell lines as *** structure of the biologically active pure compound was elucidated by 1D and 2D NMR spectroscopy and mass ***:Biological screening of *** extracts resulted in the isolation of a pentacyclic triterpenic quinone *** pure compound exhibited both in vitro a cytotoxic effect on murine P388 leukemia cells with IC_(50)value of(0.041±0.020)μg/mL and an antiplasmodial activity against the chloroquine-resistant strain FC29 of Plasmodium falciparum with an IC_(50)value of(0.052±0.030)μg/*** this interesting anti-malarial property of the lead compound,the therapeutic index was weak(0.788).In the best of our knowledge,the quinone methide pentacyclic triterpenoid derivative compound is reported for the first time in ***:The results suggest that furthers studies involving antineoplastic activity is needed for the development of this lead compound as anticancer drug.
