Five compounds were isolated from the dichloromethane fraction of a 70% ethanol extract of Epimedium sagittatum Maxim using a combination of chromatography techniques, including silica gel column chromatography, ODS column chromatography, and semipreparative high-performance liquid chromatography techniques. The structures of these five compounds were identified as 5,4′-dihydroxy-3′-prenyl-7-prenyloxyflavanone (1), 5,4′-dihydroxy-7-prenyloxyflavanone (2), 5,7,4′-trihydroxy-3′,8-diprenylflavanone (3), sebacic acid (4), and aurantiamide acetate (5), respectively, based on a comprehensive analysis of their physicochemical properties and spectroscopic data, such as NMR and MS. Notably, compound 1 was found to be a new flavonone compound, while compounds 2-5 were isolated from the Epimedium genus for the first time. Additionally, preliminary investigations indicated that compounds 1 and 3 exhibited potential anti-pulmonary fibrosis activities.

采用硅胶柱色谱、ODS柱色谱及半制备液相等色谱分离技术, 从箭叶淫羊藿(Epimedium sagittatum Maxim) 70%乙醇提取物的二氯甲烷部位分离得到5个化合物。结合其理化性质及NMR、MS等谱学技术进行结构解析, 确定其结构分别为5,4-dihydroxy-3′-prenyl-7-prenyloxyflavanone (1)、5,4′-dihydroxy-7-prenyloxyflavanone (2)、5,7,4′-trihydroxy-3′,8-diprenylflavanone (3)、癸二酸(4) 和金色酰胺醇酯(5)。其中, 化合物1为一个新的二氢黄酮类化合物, 化合物2~5为首次从淫羊藿属植物中分离得到, 化合物1和3具有潜在的抗肺纤维化活性。

Five compounds were isolated from the dichloromethane fraction of a 70% ethanol extract of Epimedium sagittatum Maxim using a combination of chromatography techniques, including silica gel column chromatography, ODS column chromatography, and semipreparative high-performance liquid chromatography techniques. The structures of these five compounds were identified as 5,4′-dihydroxy-3′-prenyl-7-prenyloxyflavanone (1), 5,4′-dihydroxy-7-prenyloxyflavanone (2), 5,7,4′-trihydroxy-3′,8-diprenylflavanone (3), sebacic acid (4), and aurantiamide acetate (5), respectively, based on a comprehensive analysis of their physicochemical properties and spectroscopic data, such as NMR and MS. Notably, compound 1 was found to be a new flavonone compound, while compounds 2-5 were isolated from the Epimedium genus for the first time. Additionally, preliminary investigations indicated that compounds 1 and 3 exhibited potential anti-pulmonary fibrosis activities.

箭叶淫羊藿又名三枝九叶草、仙灵脾, 为小檗科(Berberidaceae) 淫羊藿属多年生草本植物, 始载于《神农本草经》[1], 是我国传统中药材淫羊藿的基原之一, 以干燥叶入药。我国是淫羊藿的地理分布中心, 主要有40个淫羊藿品种, 其中箭叶淫羊藿为淫羊藿属中分布最广的品种, 主要分布在湖北、湖南、江西、河南、安徽等地[2]。箭叶淫羊藿, 性温, 味辛、甘, 归肝肾经, 具有补肾阳, 强筋骨, 祛风湿的功效[3]。现代研究表明, 箭叶淫羊藿主要含有黄酮类、苯丙素类、萜类、生物碱类等化学成分[4, 5], 并具有抗肺纤维化、抗肿瘤、抗骨质疏松、抗炎及神经保护等功效[6-9]。
肺纤维化是由多种原因引起的肺部损伤, 主要病理特征为肺组织过度修复, 成纤维细胞大量增殖、细胞外基质(extracellular matrix, ECM) 异常沉积[10]。转化生长因子-β1 (TGF-β1), 可促进成纤维细胞向肌成纤维细胞分化, 导致细胞外基质及胶原过度沉积, 从而促进肺纤维化的发生和发展[11]。有研究表明, 箭叶淫羊藿提取物可显著降低肺纤维化小鼠肺组织中TGF-β1水平, 改善细胞外基质的沉积, 具有抗肺纤维化的作用[6]。
为进一步探索箭叶淫羊藿抗肺纤维化的物质基础, 本实验对箭叶淫羊藿二氯甲烷部位的化学成分进行分离纯化, 从中分离得到5个化合物(图1), 其中化合物1为一个新的二氢黄酮类化合物, 化合物2~5为首次从淫羊藿属植物中分离得到的已知化合物, 分别鉴定为5,4′-dihydroxy-3′-prenyl-7-prenyloxyflavanone (1)、5,4′-dihydroxy-7-prenyloxyflavanone (2)、5,7,4′-trihydroxy-3′,8-diprenylflavanone (3)、癸二酸(4) 和金色酰胺醇酯(5)。采用MTT法对二氢黄酮类化合物1~3进行了抗肺纤维化活性评价, 结果发现, 化合物1和3可以明显减轻TGF-β1诱导的人正常肺上皮细胞(BEAS-2B) 损伤, 显著提高BEAS-2B细胞活力。
化合物1为黄色无定形粉末, 在254 nm下有明显紫外吸收。根据高分辨质谱数据(m/z 431.182 8 [M+Na]+, 计算值431.182 9), 推测其分子式为C25H28O5, 有12个不饱和度。1H NMR谱中显示, δH 7.20 (1H, dd, J = 8.9, 2.3 Hz), δH 7.18 (1H, d, J = 2.3 Hz), δH 6.84 (1H, d, J = 8.9 Hz) 为苯环上的一组ABX氢信号; δH 6.07 (1H, d, J = 2.3 Hz), δH 6.05 (1H, d, J = 2.3 Hz) 为苯环上的两个氢质子信号。结合13C NMR谱和DEPT谱可知, 有10个季碳信号(包括9个烯碳和1个羰基碳), 8个次甲基信号(包括7个烯碳和1个氧化次甲基碳), 3个亚甲基信号(包括1个氧化亚甲基碳) 和4个甲基信号。根据次甲基信号δC 79.3, 亚甲基信号δC 43.3和羰基信号δC 196.3, 推测化合物1具有二氢黄酮类骨架[12]。
另外, 根据烯烃氢信号δH 5.44 (1H, t, J = 6.7 Hz)、δH 5.32 (1H, m), 亚甲基氢信号δH 4.51 (2H, d, J = 6.7 Hz) 以及δH 3.38 (2H, d, J = 7.2 Hz), 甲基氢信号δH 1.79 (3H, s)、δH 1.78 (3H, s)、δH 1.78 (3H, s)、δH 1.72 (3H, s), 推测化合物1含有两个异戊烯基取代片段。结合HMBC谱中δH 1.78 (δC 25.9) 与δC 118.7 (C-12)、δC 139.3 (C-13) 相关, δH 1.79 (δC 25.9) 与δC 121.4 (C-2′′)、δC 135.2 (C-3′′) 相关, 以及1H-1H COSY相关, 可证实以上推测。然后, 根据HMBC谱中δH 4.51 (H2-11) 与δC 167.5 (C-7)、δC 139.3 (C-13) 相关以及δH 3.38 (H2-1′′) 与δC 128.3 (C-2′)、δC 155.0 (C-4′) 相关, 可确定两个异戊烯基分别连接在化合物1的7-O-和C-3′位, 其主要1H-1H COSY和HMBC相关关系见图2。
根据文献[13]报道, 当二氢黄酮类化合物在280~290 nm附近为负Cotton效应, 在330 nm附近为正Cotton效应时, C-2位为S构型。化合物1的electronic circular dichroism (ECD) 谱(图3) 在291 nm处显示负Cotton效应, 在330 nm处显示正Cotton效应, 因此化合物1的C-2位为S构型。
综上所述, 化合物1经Scifinder检索为一个新化合物, 命名为5,4′-dihydroxy-3′-prenyl-7-prenyloxyflavanone, 其碳氢数据归属见表1。
采用MTT法测试了化合物1~3对TGF-β1诱导BEAS-2B细胞损伤的影响。结果显示, 化合物1~3在10 μmol·L-1剂量下能够明显改善TGF-β1诱导的BEAS-2B细胞损伤, 显著提高BEAS-2B细胞活力, 数据详见表2, 提示化合物1和化合物3具有潜在的抗肺纤维化活性。
