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(Ranunculus 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。

1 仪器与材料
AV-300 MHz 超导核磁共振仪(德国Bruker),氘代试剂(美国CIL),Agilent 1200 系列高效液相色谱仪(美国Agilent),LCQ Advantage MAX 质谱仪(美国Finnign),Sephadex LH-20(瑞典Pharmacia),薄层色谱用硅胶(青岛海洋化工厂),ODS(日本YMC),色谱纯甲醇(山东禹王),分析纯化学试剂(天津大茂)。
刺果毛茛全草采自江西省九江县,原植物由广东药学院刘基柱教授鉴定为毛茛属植物刺果毛茛(Ranunculus muricatus Linn.)。
2 提取与分离
刺果毛茛干燥全草粗粉90%乙醇渗漉法提取3次,合并提取液减压浓缩得到浸膏1 kg。浸膏加2倍蒸馏水混悬,依次用等体积的石油醚、醋酸乙酯、正丁醇各萃取3 次,减压浓缩,分别得到石油醚部位82 g,醋酸乙酯部位27 g,正丁醇部65 g。醋酸乙酯部位经硅胶柱梯度洗脱(石油醚∶乙酸乙酯30∶1、15∶1、10∶1、5∶1、1∶1、0∶1),得到馏分R-A~F。R-D(2 g)经硅胶柱梯度洗脱(氯仿∶甲醇40 ∶1、20 ∶1、10∶1),经Sephadex LH-20 纯化及重结晶得到化合物3、4;R-E(2.5 g)经硅胶柱梯度洗脱(氯仿∶甲醇30∶1、15∶1、10∶1),经Sephadex LH-20 纯化及重结晶得到化合物1、2、5;R-F(3 g)经硅胶柱进行梯度洗脱(氯仿∶甲醇20 ∶1、10 ∶1、5 ∶1)再经Sephadex LH-20 纯化得到化合物6、7;正丁醇部位经D101 大孔树脂梯度洗脱(30%、60%、90% 甲醇/水),得到馏分R-H1~3,其中R-H1(12 g)经反相硅胶柱色谱梯度洗脱(10%、30%、60% 甲醇/水),得到馏分RH1-1~7。R-H1-(1、2、3)经聚酰胺柱色谱层析、Sephadex LH-20 及HPLC 制备等手段分离纯化得到化合物8~15。R-H1-(4、6)经反相硅胶柱色谱梯度洗脱(10%、30%、50% 甲醇/水),再Sephadex LH-20 及HPLC 制备等手段分离纯化得到化合物16、17。
