Berberis hispanica Boiss. & Reut (B. hispanica) belongs to the family Berberidaceae, which is currently used in traditional medicines. This article aimed to study the phytochemical composition and acute and subacute toxicity of B. hispanica extract in rats. The phytochemical composition of B. hispanica extract was characterized using GC-MS. The acute toxicity was investigated in vivo via the oral administration of single doses including 400, 800, 1,000, 1,200, and 1,400 mg/kg for 14 days. The subchronic toxicity was studied through oral administration of 400 mg/kg for 60 days. The findings of the phytochemical analysis of B. hispanica extract showed the presence of various phytochemical compounds. Acute toxicity results revealed serious clinical symptoms and mortalities in rats treated with 800 mg/kg up to a maximum of 1,400 mg/kg. With acute toxicity, subchronic toxicity results showed also serious signs of toxicity including biochemical and histological alterations in animals treated with 1,400 mg/kg. B. hispanica extract revealed to be toxic in rats orally treated under both subacute (>400 mg/kg) and subchronic toxicity conditions (400 mg/kg). The outcome of this study serves the society as it provides toxicological evidence of B. hispanica used in alternative medicines

Citrullus colocynthis (L.) Schrad (C. colocynthis) called colocynth is a wild species that belongs to the family cucurbitaceae. The present research work aimed to study the phytochemical composition, cytotoxic and antioxidant activities of C. colocynthis seed extract. The chemical characterization of C. colocynthis seeds was effectuated using a gas chromatograph coupled to a mass spectrometer (GC-MS). The cytotoxic activity of C. colocynthis seed extract against breast cancer cell lines (MDA-MB-231) and colon cancer cell lines (HT-29) was assessed using the WST-1 bioassay. The antioxidant power was evaluated by the DPPH assay. The phytochemical characterization of C. colocynthis seed extract showed the richness of C. colocynthis seed extract in several families of bioactive compounds. Regarding the cytotoxic activity, the IC50 (the half-maximal inhibitory concentration) of C. colocynthis seed extract in inhibiting MDA-MB-231 and HT-29 were 170.34 and 132.31 µg/mL, respectively. The cancerous cell lines MDA-MB-231 seem to be more sensitive to C. colocynthis seed extract than HT-29 cell lines. C. colocynthis seed extract exhibited a strong antioxidant power with an IC50 value of 1.37 mg/mL. Insight into the results obtained, C. colocynthis seed extract may be used as a promising weapon to fight against cancer and free radicals’ damage.
