     [摘要]采用硅胶柱色谱、sephadex LH20凝胶柱色谱、制备HPLC等多种色谱技术,从狭叶锦鸡儿(Caragana stenophylla)根80%乙醇提取物的二氯甲烷部位中分离得到14个单体化合物,依据理化性质及波谱数据分别鉴定为:2(4hydroxy3methoxylphenyl)3methoxylbenzofuran6ol (1)、mucodianin C (2)、羟基二甲氧苯基苯并呋喃醇 (isopterofuran,3)、芒柄花素 (formononetin,4)、阿夫罗摩辛 (afromosin,5)、毛蕊异黄酮 (calycosin,6)、刺槐素 (acacetin,7)、3O甲基山柰酚 (3Omethylkaempferol,8)、甘草素 (liquiritigenin,9)、异甘草素 (isoliquiritigenin,10)、variabilin (11)、白藜芦醇 (resveratrol,12)、浙贝素 (zhebeiresinol,13)、2,3dicarboxy6,7dihydroxy1(3′,4′dihydroxy)phenyl1,2 dihydronaphthalen (14)。其中化合物1是新化合物(苯并呋喃衍生物类化合物),命名为mucodianin S,化合物2,3,11,13,14为首次从锦鸡儿属中分离得到,化合物4~10为首次从狭叶锦鸡儿中分离得到。采用MTT比色法对部分单体化合物进行体外抗肿瘤活性测试,实验结果表明化合物2对人类肿瘤细胞系HepG2,HeLa具有显著的生长抑制活性,其IC50分别为(1618±095),(375±008) μmol·L-1。

    [Abstract]Fourteen compounds were isolated from the 80% ethanol extract of Caragana stenophylla root, by using a combination of various chromatographic approaches, including silica gel sephadex LH20 column chromatography, and preparative HPLC On the basis of their physical and chemical properties and spectroscopic data, their structures were elucidated as 2(4hydroxy3methoxy lphenyl)3methoxyl benzofuran6ol (1), mucodianin C (2), isopterofuran (3), formononetin (4), afromosin (5), calycosin (6), acacetin (7), 3Omethylkaempferol (8), liquiritigenin (9), isoliquiritigenin (10), variabilin (11), resveratrol (12), zhebeiresinol (13), and 2, 3dicarboxy6, 7dihydroxy1(3′, 4′dihydroxy)phenyl1, 2dihydronaphthalen (14) Compound 1 is a new benzofuran derivative, named as mucodianin S; compounds 2, 3, 11, 13, 14 were isolated from the genus Caragana for the first time, and compounds 410 were firstly isolated from Caragana stenophylla. MTT assay was used to determine their cytotoxicity of the isolated compounds against human tumor cell lines, and 2 showed cytotoxicity against human hepato cellular cancer (HepG2) and human cervical (HeLa) lines, with IC50 values of (1618±095), (375±008) μmol·L-1, respectively

    錦鸡儿属Caragana Fabr植物属于豆科,该属植物全世界大约有100多种,中国有66种,具有抗炎、镇痛、抗肿瘤、抗菌、抗氧化、抗骨质疏松、防治心血管类疾病等药理活性[12]。狭叶锦鸡儿C stenophylla Pojark是豆科锦鸡儿属灌木,分布于我国内蒙古高原的荒漠和草原地区、新疆、东北、河北、山西、陕西、宁夏、甘肃西北部。《药用植物辞典》记载狭叶锦鸡儿的根、花等部位均可以入药,具有祛风、平肝、止咳的功效[34]。目前从狭叶锦鸡儿石油醚及乙酸乙酯萃取物中分离到二苯乙烯类、黄酮类、萜类、有机酸及酯类化合物,并发现乙酸乙酯萃取物具有一定的乙酰胆碱酯酶抑制活性[5]。本研究从狭叶锦鸡儿根80%乙醇提取物的二氯甲烷萃取物中分离鉴定了14个单体化合物(图1),其中化合物1为新化合物。
