objective to observe the antitumor activities of different solution extracts of plumbago zeylanica l.in vitro.method mtt method was used to detect the inhibitory effects on four kinds of cancer cells.results chloroform extracts had significant inhibitory effects on the breast cancer cell(bre-04),the nerve cancer cell(n-04) and the lung cancer cell(lu-04),ic50 were 0.2699mg/ml and 0.2634mg/ml,0.4961mg/ml respectively.ic50 of chloroform extract on the hepg2 was 0.9379mg/ml.ic50 of petroleum ether extracts on bre-04,n-04,lu-04 and hepg2 was 0.5902mg/ml,0.5725mg/ml,0.7938mg/ml,0.6374mg/ml;ethyl acetate extracts had fairly inhibitory effects on the lu-04,ic50 was 0.7343mg/ml;n-butanol extracts and water-solubility extracts had notsignificant inhibitory effects on the four kinds of cancer cells.conclusion the antineoplastic effective parts of plumbago zeylanica l.were chloroform and petroleum ether extracts.

目的 探讨白花丹体外抗肿瘤作用的活性部位。方法 mtt染色法对白花丹五种溶剂提取物体外抗肿瘤活性进行了初步的研究。结果氯仿提取物对乳腺癌细胞（bre-04）、神经癌细胞（n-04）、肺癌细胞（lu-04）有较好的抑制生长作用，ic50分别为0.269 9 mg/ml、0.263 4 mg/ml、0.496 1 mg/ml，对肝癌细胞hepg2抑制作用差， ic50为0.937 9 mg/ml；白花丹石油醚提取部位对乳腺癌细胞（bre-04）、神经癌细胞（n-04）、肺癌细胞（lu-04）、肝癌细胞hepg2的ic50分别为0.590 2 mg/ml、0.572 5 mg/ml、0.793 8 mg/ml、0.637 4 mg/ml；乙酸乙酯提取物对肺癌细胞（lu-04）有一定的抑制作用，ic50为0.734 3 mg/ml；水溶性提取物以及正丁醇提取物无明显抑制肿瘤作用。结论白花丹氯仿提取部位、石油醚提取部位体外抗肿瘤作用较好，值得对其提取部位进一步分离纯化并研究其抗肿瘤作用机制。
