The 95% ethanol extract of Curcuma longa was subjected to isolation and purification using silica gel column chromatography, C18 column chromatography, and semi-preparative HPLC. The planar structures of the isolated compounds were elucidated by HR-MS, IR, and NMR spectroscopy. The absolute configurations of the new compounds were determined by calculated electronic circular dichroism (ECD) and DP4+ NMR analysis. Finally, three bisabolane-type sesquiterpenoids were isolated and identified from C. longa as (1R,7S)-15-norbisabolane-2-ene-11-ol-4,9-dione (1), (7S)-15-norbisabolane-1,3,5,10-tetraene-4-ol (2), and 8-hydroxyl-ar-turmerone (3). Compounds 1 and 2 were two novel 15-norbisabolane-type sesquiterpenoids.

采用硅胶柱色谱、C18柱色谱以及半制备高效液相色谱等分离技术, 对姜黄的95%乙醇提取物进行了分离纯化。运用高分辨质谱、红外光谱、核磁共振等波谱技术对化合物进行了结构鉴定, 通过计算ECD和计算NMR确定了新化合物的绝对构型。最终, 从姜黄中分离鉴定了3个没药烷型倍半萜, 其中化合物1和2为两个新颖的降碳没药烷型倍半萜, 分别为(1R,7S)-15-norbisabolane-2-ene-11-ol-4,9-dione (1) 和(7S)-15-norbisabolane-1,3,5,10-tetraene-4-ol (2), 化合物3为已知化合物8-hydroxyl-ar-turmerone。

采用硅胶柱色谱、C18柱色谱以及半制备高效液相色谱等分离技术, 对姜黄的95%乙醇提取物进行了分离纯化。运用高分辨质谱、红外光谱、核磁共振等波谱技术对化合物进行了结构鉴定, 通过计算ECD和计算NMR确定了新化合物的绝对构型。最终, 从姜黄中分离鉴定了3个没药烷型倍半萜, 其中化合物1和2为两个新颖的降碳没药烷型倍半萜, 分别为(1R,7S)-15-norbisabolane-2-ene-11-ol-4,9-dione (1) 和(7S)-15-norbisabolane-1,3,5,10-tetraene-4-ol (2), 化合物3为已知化合物8-hydroxyl-ar-turmerone。

姜黄  /  分离鉴定  /  新化合物  /  绝对构型  /  降碳没药烷型倍半萜

The 95% ethanol extract of Curcuma longa was subjected to isolation and purification using silica gel column chromatography, C18 column chromatography, and semi-preparative HPLC. The planar structures of the isolated compounds were elucidated by HR-MS, IR, and NMR spectroscopy. The absolute configurations of the new compounds were determined by calculated electronic circular dichroism (ECD) and DP4+ NMR analysis. Finally, three bisabolane-type sesquiterpenoids were isolated and identified from C. longa as (1R,7S)-15-norbisabolane-2-ene-11-ol-4,9-dione (1), (7S)-15-norbisabolane-1,3,5,10-tetraene-4-ol (2), and 8-hydroxyl-ar-turmerone (3). Compounds 1 and 2 were two novel 15-norbisabolane-type sesquiterpenoids.

姜黄(Curcuma longa L.) 为姜科植物姜黄的干燥根茎, 是我国著名的川产道地药材, 其药用历史可追溯至唐代《新修本草》。传统中医理论认为, 姜黄性温, 味苦、辛, 归肝、脾经, 具有破血行气、通经止痛之功效[1]。以姜黄为主药的成方制剂(如降脂通络软胶囊、消痛贴膏), 常用于治疗血瘀气滞导致的高脂血症、类风湿疼痛等病症[2]。
随着现代药理研究的深入, 姜黄的药用价值不断得到科学阐释。研究表明, 姜黄具有抗炎[3]、抗癌[4]、抗氧化[5]、脂质调节[6]等多种生物活性, 为其传统功效提供了有力的药理学依据。这些活性的多样性与其化学成分密切相关, 其中姜黄素类和萜类成分被认为是两类主要的活性物质[7]。目前, 姜黄素类成分的研究已较为系统, 相关药理研究与制剂开发取得广泛进展。相较而言, 姜黄中萜类成分的研究仍较薄弱[8], 这在一定程度上限制了对其药用价值的全面认识。
姜黄中萜类成分以倍半萜类为主, 目前已从中分离得到的20余种该类成分, 主要包括吉马烷型、愈创木烷型、长松针烷型、桉烷型、没药烷型、蒈烷型、榄香烷型、苍耳烷型等结构类型, 其中没药烷型倍半萜数量最多[9]。没药烷型倍半萜作为一类重要的单环倍半萜, 在自然界中分布广泛, 具有抗病毒、抗炎、抗动脉粥样硬化、舒张血管等多种活性[9-12], 显示出良好的药用潜力。本课题组在前期的研究中, 已从姜黄中分离鉴定出10余个新的倍半萜化合物[1,6,8,9,12-15]。
作为前期工作的延续, 本研究对姜黄的化学成分开展了进一步的系统分离与鉴定, 成功获得3个没药烷型倍半萜(结构见图1)。其中, 化合物1和2为两个结构新颖的降碳没药烷型倍半萜, 该发现不仅进一步丰富了姜黄中萜类化学成分的多样性, 也为后续深入研究该类成分的生物活性与作用机制奠定了重要的物质基础。
化合物1为无色油状物, [α]$ {}_{\mathrm{D}}^{20} $ -29.9 (c 0.13, MeOH)。根据其准分子离子峰(+)-HR-ESI-MS m/z 261.146 4 [M+Na]+ (计算值261.146 1, C14H22O3Na), 推断化合物的分子式为C14H22O3, 不饱和度为4。红外光谱显示其可能含有羟基(3 306 cm-1) 和α,β不饱和酮(1 688 cm-1)。由表1可见, 1H NMR显示有3个甲基信号[δH 0.91 (3H, d, J = 6.6 Hz), 1.21 (6H, s)]、1个羟基质子信号[δH 3.91 (1H, brs)] 和2个烯烃质子信号[δH 5.91 (1H, dd, J = 10.8, 2.4 Hz), 6.93 (1H, dt, J = 10.8, 2.4 Hz)]。13C NMR、DEPT显示有14个碳信号, 其中包括3个甲基(δC 16.7, 29.9, 29.9)、4个亚甲基(δC 25.2, 38.0, 49.2, 55.3)、4个次甲基[其中包含2个烯烃碳(δC 130.3, 154.9)、2个叔碳(δC 32.6, 41.5)] 和3个季碳[其中包含2个羰基碳(δC 199.1, 211.2) 和1个连氧季碳(δC 70.0)]。以上数据提示化合物1可能为一个C-15位降碳的没药烷型倍半萜。与文献对比发现, 化合物1的核磁数据与已知化合物turmerone Q的数据类似[16], 区别在于化合物1中C-4的化学位移(δC 199.1) 且C-5对应δC 38.0 [δH 2.36 (2H, m)], 而在turmerone Q中, C-4并非羰基碳, 且C-5为连氧碳。初步推断化合物1的C-4被氧化为羰基, 从而与C-2/C-3构成α,β-不饱和酮体系, 且C-5上无羟基取代。
为了进一步确定化合物1的结构, 进行了2D NMR实验。1H-1H COSY和HMBC谱中的关键相关信号如图2所示, 在HMBC谱中, 观察到H2-6与C-4 (δC 199.1) 以及H-2与C-4的远程相关, 这直接证实了C-4为羰基碳并处于α,β-不饱和系统中。同时, 1H-1H COSY谱中H2-5和H2-6相关、结合C-5的化学位移, 确证C-5为未连氧的亚甲基。基于以上证据, 化合物1的平面结构得以确定。
进一步确定化合物1的绝对构型, 对于类似的没药烷结构, 文献[12]证据表明, C-1处是S构型(1S,7R; 1S,7S) 时旋光值为正, 而是R构型(1R,7R; 1R,7S) 为负值。因此, 根据化合物1的旋光值为-29.9 (c 0.13, MeOH), 将C-1的绝对构型确定为R。通过计算核磁进一步确定C-7的绝对构型, 由于化合物1的实验与计算的 13C NMR化学位移回归分析相关系数非常接近, 因此在mPW1PW91/6-311+G(d,p) 水平上计算了(1R,7S) 和(1R,7R) 的理论NMR数据。基于1H和13C NMR数据的DP4+概率分析(图3) 显示(1R,7S) 明显优于(1R,7R)。因此, 化合物1的绝对构型确定为(1R,7S)-1, 并命名为(1R,7S)-15-norbisabolane-2-ene-11-ol-4,9-dione。
化合物2为无色油状物, [α]$ {}_{\mathrm{D}}^{20} $ +42.0 (c 0.10, MeOH)。(+)-HR-ESI-MS给出准分子离子峰m/z 227.141 4 [M+Na]+ (计算值227.140 6, C14H20ONa), 推断化合物的分子式为C14H20O, 不饱和度为5。红外光谱提示其可能含有羟基(3 321 cm-1)、苯环或双键(1 515, 1 459 cm-1)。由表1可见, 1H NMR谱信号显示20个质子吸收峰, 其中包括1个双峰甲基[δH 1.17 (3H, d, J = 8.4 Hz)]、2个单峰甲基[δH 1.49 (3H, s), 1.64 (3H, s)]、1个烯质子信号[δH 5.10 (1H, m)]、2组苯环氢信号[δH 6.75 (2H, m), 7.02 (2H, m)] 和1个羟基质子信号[δH 8.08 (1H, brs)]。13C NMR、DEPT谱显示出14个碳信号, 其中包括3个甲基(δC 17.7, 23.1, 25.8)、2个亚甲基(δC 26.9, 39.4)、6个次甲基[包含4个芳香碳(δC 115.9, 115.9, 128.6, 128.6), 1个烯烃碳(δC 125.4) 和1个叔碳(δC 39.4)]、3个季碳(δC 131.6, 139.0, 156.3)。化合物2的核磁数据与文献[17]报道的α-curcumene相似, 两者差别主要在化合物2的苯环上少了1个甲基信号, 再综合其质谱信息和羟基信号推测化合物2可能是α-curcumene苯环上一个甲基被羟基取代的衍生物, 即一个含对位羟基取代的降碳苯环倍半萜。1H-1H COSY和HMBC谱显示的主要相关信号如图2所示, HMBC谱中观察到H-2、H-3、H-5、H-6均与季碳C-4 (δC 156.3) 存在远程相关, 并且C-4向低场移动(δC 156.3), 符合连氧季碳的特征。综合以上信息, 化合物2的平面结构得以确定。
基于所确定的平面结构, 化合物2仅存在有一个手性中心(C-7), 其绝对构型仅有(7S) 和(7R) 两种可能性, 在本研究中, 通过计算ECD对化合物2的绝对构型进行了确证。使用IEFPCM模型, 以甲醇为溶剂, 在CAM-B3LYP/DGDZVP水平计算了(7S)-2和(7R)-2的理论ECD谱(图4), 在200~400 nm的波长内, (7S)-2的计算ECD谱与实验ECD谱非常吻合。因此, 将化合物2的绝对构型确定为7S, 并命名为(7S)-15-norbisabolane-1,3,5,10-tetraene-4-ol。
化合物3为无色油状液体; (+)-HR-ESI-MS m/z 255.135 1 [M+Na]+ (计算值255.135 6); 1H NMR (acetone-d6, 600 MHz) 和13C NMR (acetone-d6, 150 MHz) 数据见表1。其数据与文献[18]报道的8-hydroxyl-ar-turmerone几乎一致, 将化合物3鉴定为8-hydroxyl-ar-turmerone。
姜黄是亚洲地区广泛使用的药食同源植物, 其倍半萜类成分因结构多样、生物活性显著而备受关注[19-23]。在前期系统研究的基础上, 本研究综合运用多种分离与结构鉴定技术, 从姜黄中成功分离并鉴定了2个结构新颖的降碳没药烷型倍半萜(1和2) 和1个已知没药烷型倍半萜(3), 并通过计算ECD和计算NMR确定了新化合物的绝对构型。值得注意的是, 尽管姜黄中富含没药烷型倍半萜, 但仅在环上C-4位发生甲基降碳的结构很少见, 除了课题组前期报道的一对在支链降碳没药烷型倍半萜对映异构体外, 天然产物仅见1例相关报道[20]。本研究发现的2个新化合物均具有该结构特征: 化合物1在C-4位发生甲基氧化, 形成α,β不饱和酮结构; 化合物2则在C-4位发生羟基取代, 形成苯环对位羟基取代的降碳没药烷结构。本研究不仅进一步丰富了姜黄倍半萜类化学成分库, 也为后续深入研究该类成分的生物活性与合成机制提供了重要的物质基础与理论参考。后续研究将围绕这两个新化合物的生物活性开展系统探究, 以进一步揭示其潜在药用价值。
