The methanol extract from Morinda citrifolia fruits was tested for cytotoxicity activity on the MTT assay. The appearance of cytotoxic changes after exposure to the extract was in a concentration dependent manner. The median lethal concentrations (LC(50)) of the extract in baby hamster kidney (BHK) cells, African green monkey kidney (Vero) cells and human laryngeal carcinoma (Hep2) cells were found to be 2.5, 3 and 5 mg/mL, respectively. A concentration of 0.1 mg/mL of crude extract exhibited cytotoxic activity against breast cancer (MCF7) and neuroblastoma (LAN5) cell lines at 29% and 36%, respectively. The same concentration of extract showed no toxicity to Vero and very little toxicity to BHK (6%) and Hep2 (13%) cells.
对海巴戟果实的甲醇提取物进行了MTT法细胞毒性活性测试。暴露于提取物后细胞毒性变化的出现呈浓度依赖性。该提取物在幼仓鼠肾（BHK）细胞、非洲绿猴肾（Vero）细胞和人喉癌（Hep2）细胞中的半数致死浓度（LC(50)）分别为2.5、3和5 mg/mL。浓度为0.1 mg/mL的粗提取物对乳腺癌（MCF7）和神经母细胞瘤（LAN5）细胞系的细胞毒性活性分别为29%和36%。相同浓度的提取物对Vero细胞无毒性，对BHK细胞（6%）和Hep2细胞（13%）毒性很小。
