Isolable from the autumn crocus, Colchicum autumnale, it is less toxic than colchicine and is used as an antineoplastic. It has a role as an antineoplastic agent and a microtubule-destabilising agent. It is an alkaloid and a secondary amino compound.

简介秋水仙碱又称秋水仙素,大环型生物碱的一种。其通常存在于百合科植物嘉兰和丽江山慈菇,含量分别为0.11%和0.1%。由植物秋水仙中提取的生物碱,能抑制纺锤丝的形成,从而延迟着丝粒的分裂。由此可将有丝分裂细胞阻断于中期相,也可阻断减数分裂。农业中利用秋水仙碱上述作用培植多倍体新品种。作染色体分析时常用秋水仙碱处理以获得较多的中期相细胞供分析用。
用途秋水仙碱可用作抗肿瘤药物,主要抑制骨髓造血机能,造成白细胞和血小板减少,急性肾功能衰竭,长期吸收可发生粒性白细胞缺乏症,再生障碍性贫血和脱发等;对急性痛风性关节炎有特效。临床用于缓解急性痛风发作时发生的疼痛。
