刺果毛茛Ranunculus muricatus Linn. 別名:野芹菜,是毛茛科毛茛屬一年生草本植物,生長于潮濕田野,河溝道旁,廣泛分布于亞洲、歐洲、大洋洲及北美洲。刺果毛茛在印度西北部哈里亞納邦民間主要用于治療扁桃體炎[1],而在我國毛茛屬植物入藥歷史悠久,如石龍芮(Ranunculus sceleratus Linn.)、毛茛(Ranunculus japonicas Thunb.)、小毛茛(Ranunculus termatus Thunb.)等。據(jù)報(bào)道,毛茛屬植物提取物多具有抗菌、抗炎、抗腫瘤、抗病毒等方面活性[2,3],特別是抗結(jié)核病方面療效確切[4,5]。目前,關(guān)于刺果毛茛化學(xué)成分研究的報(bào)道較少,所以,我們對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進(jìn)行了深入的化學(xué)成分研究。從醋酸乙酯萃取部位分離得到了7 個(gè)化合物(1~7);從正丁醇萃取部位分離得到了10 個(gè)黃酮苷(8~17)。除化合物4 外,其他均為首次從刺果毛茛中分離得到,本文報(bào)道這些化合物的提取分離和結(jié)構(gòu)鑒定。

1 儀器與材料

AV-300 MHz 超導(dǎo)核磁共振儀(德國Bruker),氘代試劑(美國CIL),Agilent 1200 系列高效液相色譜儀(美國Agilent),LCQ Advantage MAX 質(zhì)譜儀(美國Finnign),Sephadex LH-20(瑞典Pharmacia),薄層色譜用硅膠(青島海洋化工廠),ODS(日本YMC),色譜純甲醇(山東禹王),分析純化學(xué)試劑(天津大茂)。

刺果毛茛全草采自江西省九江縣,原植物由廣東藥學(xué)院劉基柱教授鑒定為毛茛屬植物刺果毛茛(Ranunculus muricatus Linn.)。

2 提取與分離

刺果毛茛干燥全草粗粉90%乙醇滲漉法提取3次,合并提取液減壓濃縮得到浸膏1 kg。浸膏加2倍蒸餾水混懸,依次用等體積的石油醚、醋酸乙酯、正丁醇各萃取3 次,減壓濃縮,分別得到石油醚部位82 g,醋酸乙酯部位27 g,正丁醇部65 g。醋酸乙酯部位經(jīng)硅膠柱梯度洗脫(石油醚∶乙酸乙酯30∶1、15∶1、10∶1、5∶1、1∶1、0∶1),得到餾分R-A~F。R-D(2 g)經(jīng)硅膠柱梯度洗脫(氯仿∶甲醇40 ∶1、20 ∶1、10∶1),經(jīng)Sephadex LH-20 純化及重結(jié)晶得到化合物3、4;R-E(2.5 g)經(jīng)硅膠柱梯度洗脫(氯仿∶甲醇30∶1、15∶1、10∶1),經(jīng)Sephadex LH-20 純化及重結(jié)晶得到化合物1、2、5;R-F(3 g)經(jīng)硅膠柱進(jìn)行梯度洗脫(氯仿∶甲醇20 ∶1、10 ∶1、5 ∶1)再經(jīng)Sephadex LH-20 純化得到化合物6、7;正丁醇部位經(jīng)D101 大孔樹脂梯度洗脫(30%、60%、90% 甲醇/水),得到餾分R-H1~3,其中R-H1(12 g)經(jīng)反相硅膠柱色譜梯度洗脫(10%、30%、60% 甲醇/水),得到餾分RH1-1~7。R-H1-(1、2、3)經(jīng)聚酰胺柱色譜層析、Sephadex LH-20 及HPLC 制備等手段分離純化得到化合物8~15。R-H1-(4、6)經(jīng)反相硅膠柱色譜梯度洗脫(10%、30%、50% 甲醇/水),再Sephadex LH-20 及HPLC 制備等手段分離純化得到化合物16、17。
