刺果毛茛 Ranunculus muricatus Linn. 别名:野
芹菜,是毛茛科毛茛属一年生草本植物,生长于潮湿
田野,河沟道旁,广泛分布于亚洲、欧洲、大洋洲及北
美洲。刺果毛茛在印度西北部哈里亚纳邦民间主要
用于治疗扁桃体炎[1],而在我国毛茛属植物入药历
史悠久,如石龙芮(Ranunculus sceleratus Linn.)、毛
茛(Ranunculus japonicas Thunb.)、小毛茛(Ranun-
culus termatus Thunb.)等。据报道,毛茛属植物提取
物多具有抗菌、抗炎、抗肿瘤、抗病毒等方面活
性[2,3],特别是抗结核病方面疗效确切[4,5]。目前,
关于刺果毛茛化学成分研究的报道较少,所以,我们
对刺果毛茛全草乙醇提取物的醋酸乙酯萃取部位和
正丁醇萃取部位进行了深入的化学成分研究。从醋
酸乙酯萃取部位分离得到了 7 个化合物(1 ~ 7) ;从
正丁醇萃取部位分离得到了 10 个黄酮苷(8 ~ 17)。
除化合物 4 外,其他均为首次从刺果毛茛中分离得
到,本文报道这些化合物的提取分离和结构鉴定。
