从海南产见血封喉[Antiaris toxicaria (Pers.) Lesch.]乳汁的乙醇提取物中分离得到6个化合物, 经现代波谱技术, 包括红外、一维、二维核磁共振谱和高分辨质谱, 上述化合物的结构分别鉴定为: toxicarioside I (1), 毒毛旋花子苷元 (2), 杠柳苷元(3), (3β,5α,14β,17α)-3,14-二羟基孕甾-20-酮(4), α-生育酚(5)和3,4,5-三甲氧基苯酚(6), 其中化合物1为新的强心苷, 化合物45为首次从该植物中分离得到. 经MTT法进行体外细胞毒活性测试, 结果表明化合物13对慢性髓原白血病细胞(K562)、人胃癌细胞(SGC-7901)和人肝癌细胞(SMMC-7721)的增殖显示了抑制活性, 其IC50值范围为0.001~12.3 μmol•L-1.

Six compounds were isolated from the ethanol extract of the latex of Antiaris toxicaria (Pers.) Lesch collected in Hainan. The structures were established as toxicarioside I (1), strophanthidin (2), periplogenin (3), (3β,5α,14β,17α)-3,14-dihydroxypregnan-20-one (4), α-tocopherol (5) and 3,4,5-trimethoxy- phenol (6) by spectroscopic methods (IR, 1D-, 2D-NMR and HR-ESIMS). Among them, compound 1 was a new cardenolide, compounds 4 and 5 were isolated from this plant for the first time. Compounds 13 showed cytotoxic effects on chronic myelogenous leukemia (K562), human gastric carcinoma (SGC-7901) and human hepatoma (SMMC-7721) cell lines with IC50 values ranged from 0.001 to 12.3 μmol•L-1.
