The common fern, bracken (Pteridium aquilinum), is well known for its toxic effects on livestock due principally to the carcinogenic constituent ptaquiloside (1), although other toxins are present including the cyanogenic glycoside, prunasin (2). Here, we report an improved and relatively “green” process for the isolation of 1 and 2 from fresh bracken fronds and the evaluation of 1 for cytotoxicity
常见的蕨类植物蕨菜 (Pteridium aquilinum) 因其对牲畜的毒性作用而广为人知,主要是由于致癌成分 ptaquiloside (1),尽管还存在其他毒素,包括
氰苷、prunasin (2)。在这里,我们报告了一种改进且相对“绿色”的过程,用于从新鲜蕨菜叶中分离 1 和 2,并评估 1 对几种癌
细胞系的细胞毒性。结果表明,相对于非癌性视网膜上皮细胞,1 对癌细胞显示出选择性毒性,预计 1 的改进方法将有助于进一步探索其药理特性。
