Phytochemicals from may be potent in inducing mitochondrial-dependent apoptosis via the opening of the mitochondrial permeability transition (MPT) pore. Therefore, this study investigated the effects of stigmasterol isolated from the chloroform fraction of (CFAB) and also the increasing concentration of CFAB on the opening of rat liver mitochondrial permeability transition (MPT) pore. Fractionation of CFAB on column chromatography yielded a needle-like crystal which structure was elucidated by standard spectroscopic techniques. The effects of stigmasterol and CFAB on MPT pore opening were assayed spectrophotometrically. Also, the effect of CFAB on mitochondrial ATPase (mATPase) activity and cytochrome c (Cyt c) release were determined. Stigmasterol isolated from CFAB induced MPT pore opening significantly (p<0.05) when compared withthe control. Similarly, CFAB significantly (p<0.05) induced MPT potosis through the opening of the mitochondrial permeability transition pore, activation of mitochondrial ATPase (mATPase) activity and cytochrome c release. The neem ( ) have been used in herbal medicine for the treatment of multiple diseases, particularly cancer. The mechanism of anti-cancer properties of neem are far from clear. However, it is well accepted that anti-cancer effects of neem is mediated via its hepatic anti-oxidant activity. In the present review, we are going to classify and studies about anti-cancer activity of neem via its hepatic anti-oxidant activity. We also summarize its active ingredients and some therapeutic and toxic dosage forms. A systematic search in the literature was performed in PubMed, Scopus, Embase, Cochrane Library, Web of Science, as well as Google Scholar pre-print database using all available MeSH terms for neem, , anti-cancer, anti-tumor, carcinogen, liver, antioxidant activity, neem ingredients,
