The chemical constituents in the bark of Eucommia ulmoides were isolated and purified using chromatographic techniques, including silica gel, Sephadex LH-20, ODS, MCI, and semi-preparative HPLC. The structures of the compounds were elucidated by spectroscopic analyses (NMR, IR, UV, and MS). A total of six compounds were identified as duzhonglactone (1), (7S, 8R)-4-hydroxy-3, 3′, 5′-trimethoxy-8, 9-dinor-8, 4′-oxyneoligna-7, 9-diol-7′-aldehyde (2), armaosigenin (3), (-) evofolin B (4), N-trans-feruloyltyramine (5), and C-veratroylglycol (6). Among them, compound 1 was a new five-membered ring lactone, while compounds 2-5 were isolated for the first time from Eucommia ulmoides bark. Furthermore, compounds 2-4 demonstrated antioxidant activity, with IC50 values for 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging of 46.34 ± 5.80, 74.17 ± 8.71, and 78.02 ± 8.94 μg·mL-1, and for 2, 2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) scavenging of 50.56 ± 1.35, 54.37 ± 3.04, and 55.61 ± 3.41 μg·mL-1, respectively.

杜仲(Eucommia ulmoides Oliv.), 又称胶木、思仲, 属于杜仲科药用植物, 其干燥树皮在我国已有两千多年的药用历史, 是中国传统药材之一。据《神农本草经》记载: “杜仲药性甘温, 微辛, 适用于治疗肝肾不足、腰膝酸痛、筋骨无力、头晕目眩等症状。此外, 亦可用于肝肾亏虚引起的妊娠漏血、胎动不安”[1, 2]。杜仲主要分布于云南、湖南、河南和甘肃等地。其化学成分主要包括木脂素类、环烯醚萜类、黄酮类、酚酸类及萜类等, 具备降血糖、降血压、调血脂、抗氧化、抗肿瘤、抗骨质疏松症等多重药理作用[3-8], 广泛应用于中成药及中医临床配方中。
为了深入揭示其药理活性的化学物质基础, 本实验对杜仲皮醇提取物的二氯甲烷层进行了化学成分研究, 并从中分离并鉴定出6个化合物。这些化合物分别是杜仲内酯(1)、(7S, 8R)-4-hydroxy-3, 3′, 5′-trimethoxy-8, 9-dinor-8, 4′-oxyneoligna-7, 9-diol-7′-aldehyde (2)、armaosigenin (3)、(-) evofolin B (4)、N-反式阿魏酸酪酰胺(5)、C-藜芦酰乙二醇(6), 结构见图1。此外, 本实验还研究了这些单体化合物对自由基的抗氧化能力。结果表明, 化合物2~4表现出一定的抗氧化能力, 对DPPH自由基清除活性的IC50值分别为46.34 ± 5.80、74.17 ± 8.71、78.02 ± 8.94 μg·mL-1, 对ABTS自由基清除活性的IC50值分别为50.56 ± 1.35、54.37 ± 3.04、55.61 ± 3.41 μg·mL-1。
化合物1  橙黄色油状物质, 香草醛-浓硫酸反应(TLC) 斑点显灰色; [α]$ {}_{\mathrm{D}}^{20} $ +60.02 (c 0.2, MeOH), HR-ESI-MS m/z 221.087 1 [M+Na]+ (C10H14O4Na+, 计算值: 221.087 4), 确定该化合物分子式是C10H14O4, 相对分子质量是198.089 2, 不饱和度为4。UV (MeOH) λmax (log ε): 218 (7.32); IR光谱提示结构中具有甲基(2 941 cm-1)、羟基(3 443 cm-1)、酯羰基(1 768 cm-1)、羰基(1 714 cm-1) 和双键(1 634 cm-1) 等官能团。1H NMR (600 MHz, CD3OD) 谱(表1) 显示有1对反式双键质子信号δH 6.86 (1H, dd, J = 16.0, 6.1 Hz, H-6)、6.34 (1H, dd, J = 16.0, 1.4 Hz, H-7); 1个次甲基质子信号δH 4.24 (1H, dd, J = 6.1, 1.4 Hz, H-5); 2个亚甲基质子信号δH 2.64 (2H, m, H-3)、2.42 (1H, ddd, J = 13.0, 9.6, 7.0 Hz, H-2b)、2.00 (1H, ddd, J = 13.0, 9.6, 7.9 Hz, H-2a); 以及2个甲基质子信号δH 2.29 (3H, s, H-9)、1.39 (3H, s, H-10)。13C NMR (150 MHz, CD3OD) 谱(表1) 和DEPT谱显示有10个碳信号, 其中包括2个羰基碳信号δC 200.8 (C-8) 和179.7 (C-1); 2个双键碳信号δC 145.8 (C-6) 和133.4 (C-7); 1个次甲基碳信号δC 77.1 (C-5); 2个亚甲基碳信号δC 31.2 (C-2) 和30.2 (C-3) 以及2个甲基碳信号δC 27.2 (C-9) 和23.6 (C-10)。1H-1H COSY谱中显示存在2个自旋偶合系统, 分别为H-5/H-6/H-7和H-2/H-3 (图2)。将化合物1的 1H NMR和13C NMR谱和(+)-(R)-pinnatolide的核磁共振氢谱和碳谱数据[9, 10]进行比较, 两者五元内酯环部分的数据比较相似, 侧链部分不同。再结合1H-1H COSY谱确定的自旋偶合体系及HMBC图谱中H-2与C-1、C-4相关, H-3与C-1、C-4相关, H-10与C-3、C-4相关确定五元内酯环部分的结构; HMBC图谱中H-6、H-7与C-8相关, H-9与C-8相关(图2) 确定了侧链部分的结构; 最后HMBC图谱中H-5与C-4、C-10相关, H-10与C-5、C-3相关将五元内酯环与侧链连接在一起。从而确定了化合物1的平面结构如图2所示。
在NOESY相关谱中(图2) 可以观察到10-CH3与5-H、H-2a之间存在明显相关信号, 提示10-CH3、5-H与H-2a处于同一侧, 从而推测化合物1的相对构型为4β-CH3, 5α-OH。化合物1的绝对构型可能为(4R, 5S) 或(4S, 5R) 两种对映异构体, 根据旋光色散理论, 手性分子的旋光特性与绝对构型存在直接关联, 因此采用旋光色散(ORD) 计算方法进一步确定化合物1的绝对构型[11, 12]。通过Gaussian 09软件, 在B3LYP-D3(BJ)/6-31G*水平下完成两种异构体的结构优化与旋光值计算: (4R, 5S) 异构体的计算旋光值为-215.35, 与化合物1实验测得的旋光值+60.02方向相反, 尽管计算值和实验值存在数据差异, 但方向性匹配是构型判定的核心依据, 且偏差处于合理范围, 故确定化合物1的绝对构型是4S, 5R。综合上述波谱数据和构型分析结果, 化合物1被鉴定为新的五元环内酯类化合物, 命名为杜仲内酯, 结构如图1所示。
本实验对化合物1~6都进行了抗氧化能力的评估, 以维生素C (Vc) 为阳性对照药, 抗氧化活性结果(表2) 显示, 化合物2~4展现出一定的抗氧化能力, 而化合物1几乎不具备抗氧化能力, 化合物5和6则表现出较弱的抗氧化能力。其中, 化合物2是抗氧化活性最强的单体化合物, 其清除DPPH自由基的IC50值为46.34 ± 5.80 μg·mL-1, 清除ABTS自由基的IC50值为50.56 ± 1.35 μg·mL-1。
本实验从杜仲皮中分离得到6个化合物, 其中化合物1是新的五元环内酯类化合物, 化合物2~5首次从杜仲皮中分离得到, 此外, 本实验对化合物1~6都进行了抗氧化能力的评估, 结果显示化合物2~4展现出一定的抗氧化能力, 其中, 化合物2为抗氧化活性最高的单体化合物, 清除DPPH自由基的IC50值是46.34 ± 5.80 μg·mL-1, 清除ABTS自由基的IC50值是50.56 ± 1.35 μg·mL-1。本实验的结果丰富了杜仲皮的化学成分类型, 此外为杜仲抗氧化的药效物质基础提供了一定的依据。

参考文献[18]报道的方法, 精密称取3.94 mg DPPH粉末, 加入无水乙醇配制成浓度为0.1 mmol·L-1的工作液备用(吸光度在0.9~1.0之间)。精密吸取40 μL不同浓度的待测样品溶液(300、200、100、50、25、10 μg·mL-1) 加入96孔板中, 随后加入160 μL DPPH溶液, 在室温下避光反应30 min。在517 nm波长下测得的吸光度记为(A1), 以160 μL无水乙醇替代DPPH乙醇溶液测得的吸光度记为(A2), 以40 μL无水乙醇替代样品溶液测得的吸光度记为(A0)。同时, 以相同浓度的维生素C作为对照, 每个浓度平行测定3次。根据公式计算样品对DPPH自由基的清除率, 其清除能力用IC50表示, 清除率计算见公式(1)。
$\mathrm{DPPH} \cdot \text { 清除率 }=\left[1-\left(A_1-A_2\right) / A_0\right] \times 100 \%$
参考文献[19]报道的方法, 将7 mmol·L-1 ABTS与2.45 mmol·L-1过硫酸钾等体积混合, 在室温且避光的条件下反应14~18 h。第二天, 使用无水乙醇进行稀释, 稀释倍数约为20~40倍, 摇匀后静置10 min, ABTS工作液即配制完成(吸光度约为0.7)。精密吸取40 μL不同浓度的待测样品溶液(300、200、100、50、25、10 μg·mL-1), 加入到96孔板中, 随后加入160 μL ABTS溶液, 在室温下避光反应30 min。在734 nm波长下测得的吸光度记为(A3), 以160 μL无水乙醇替代ABTS溶液测得的吸光度记为(A4); 以40 μL无水乙醇替代样品溶液测得的吸光度记为(A5)。同时, 以相同浓度的维生素C作为对照, 每个浓度平行测定3次。根据公式计算样品对ABTS自由基的清除率, 其清除能力用IC50表示, 清除率计算见公式(2)。
$\text { ABTS•清除率 }=\left[1-\left(A_3-A_4\right) / A_5\right] \times 100 \%$
采用GraphPad Prism 9.5.1统计软件进行数据分析, 数据以均数±标准差($ \overline{x} $ ± s) 表示, 所有实验均重复3次, 计算半数抑制浓度。
