A new compound was isolated from the 95% ethanolic extract of the rhizomes of Curcuma longa L. using silica gel column chromatography, medium pressure liquid chromatography, and semi-preparative high performance liquid chromatography. The structure and absolute configuration of the compound was elucidated by HR-ESI-MS, NMR, and electronic circular dichroism (ECD) calculations. It is a novel sesquiterpenoid, which is named as isoturmeronol B (1). The carbon skeleton of compound 1 is similar to that of bisabolane-type sesquiterpenoid. The only difference is that the methyl group at C-4 in bisabolene-type sesquiterpenoid is migrated to C-5 in compound 1. Besides, the anti-inflammatory and antioxidant activities of the compound 1 were evaluated. The results showed that 1 has no anti-inflammatory and antioxidant activities.

采用硅胶柱色谱、中压液相色谱、半制备高效液相色谱等分离技术, 从姜黄95%乙醇提取物中分离得到1个新化合物。结合质谱、核磁、计算ECD等手段确定了化合物的结构及绝对构型, 发现化合物为一个结构新颖的倍半萜类成分, 将其命名为isoturmeronol B (1)。化合物1的骨架与没药烷型倍半萜相似, 唯一区别在于化合物1在没药烷型倍半萜骨架的基础上, C-4位的甲基迁移至C-5位。对化合物1的抗炎和抗氧化活性进行了评价, 结果表明化合物1无抗炎及抗氧化活性。

A new compound was isolated from the 95% ethanolic extract of the rhizomes of Curcuma longa L. using silica gel column chromatography, medium pressure liquid chromatography, and semi-preparative high performance liquid chromatography. The structure and absolute configuration of the compound was elucidated by HR-ESI-MS, NMR, and electronic circular dichroism (ECD) calculations. It is a novel sesquiterpenoid, which is named as isoturmeronol B (1). The carbon skeleton of compound 1 is similar to that of bisabolane-type sesquiterpenoid. The only difference is that the methyl group at C-4 in bisabolene-type sesquiterpenoid is migrated to C-5 in compound 1. Besides, the anti-inflammatory and antioxidant activities of the compound 1 were evaluated. The results showed that 1 has no anti-inflammatory and antioxidant activities.

姜黄为姜科植物姜黄Curcuma longa L.的干燥根茎, 又名宝鼎香、黄姜, 是一味著名的川产道地药材, 其中犍为县的姜黄品质上佳, 为姜黄的主要产区之一[1]。姜黄的功效始载于《唐本草》: “主心腹结积, 疰忤, 下气, 破血, 除风热, 消痈肿”, 而今《中华人民共和国药典》将其功效总结为: “破血行气, 通经止痛”, 现中医常用姜黄治疗各种妇科疾病及多种伤痛痹症[2]。现代药理学研究表明, 姜黄具有抗肿瘤、抗炎、抗氧化、抗菌的药理活性, 此外, 姜黄在治疗自身免疫性疾病、神经系统疾病、心血管疾病和糖尿病等疾病方面也具有独特的优势[3-6]。相关化学研究表明, 姜黄的主要活性成分为姜黄素类和萜类, 其中关于姜黄素类成分的研究较为广泛, 不论是其药理作用, 还是制剂方法皆有诸多研究[7-10]。而关于姜黄中的另一大类成分——萜类成分的研究则相对较少, 值得进一步的探索。
文献研究表明, 姜黄中的萜类成分多为倍半萜类化合物, 类型除主要的没药烷型外, 还可见杜松烷型、吉玛烷型、桉叶烷型、愈创木烷型等[11]。基于此, 本课题组前期运用多种色谱及波谱技术从姜黄中分离鉴定了多个倍半萜, 包括2个新骨架倍半萜和一些没药烷型倍半萜[12-15]。本研究继续对姜黄中的倍半萜类成分进行分离鉴定, 得到1个结构新颖的倍半萜, 命名为isoturmeronol B。该倍半萜的骨架与没药烷型倍半萜类似, 区别在于甲基由C-4迁移到了C-5上, 目前在姜黄中仅报道过1个该骨架类型的化合物[16]。此外, 本研究还对化合物的抗炎和抗氧化活性进行了评价, 发现化合物1无抗炎及抗氧化活性。
化合物1为无色油状物, [α]$ {}_{\mathrm{D}}^{20} $ +30.0 (c 0.01 MeOH)。(+)-HR-ESI-MS给出准离子峰m/z 255.135 5 [M+Na]+ (计算值为C15H20O2Na: 255.136 1), 提示其分子式为C15H20O2, 不饱和度为6。IR光谱显示化合物1存在羰基(1 673 cm-1)、苯环或双键(1 612、1 500 cm-1) 和羟基(3 409 cm-1) 的特征吸收峰, UV显示在229 nm处有最大吸收峰, 表示化合物1可能含有α, β-不饱和酮系统。1H NMR (表 1) 显示化合物1有一个ABX偶合系统的苯环结构[δH 6.70 (1H, d, J = 8.4 Hz), 6.79 (1H, dd, J = 8.4, 2.4 Hz), 6.96 (1H, d, J = 2.4 Hz)], 1个烯氢信号[δH 6.16 (1H, brs)], 以及3个单峰甲基信号[δH 2.19 (3H, s), 2.07 (3H, brs), 1.85 (3H, brs)] 和1个双峰甲基信号[δH 1.19 (3H, d, J = 7.2 Hz)]。13C NMR和DEPT谱显示该化合物有15个碳信号, 可归属为4个甲基、1个亚甲基、5个次甲基[包含4个烯碳(δC 116.2, 127.9, 128.4, 124.8)] 和5个季碳[包含1个酮羰基碳(δC 200.5) 和4个双键季碳(δC 133.4, 153.0, 129.2, 154.8)]。根据以上波谱学数据, 初步推断化合物1为一个含有苯环的单环倍半萜。查阅文献并对比核磁数据, 发现化合物1与turmeronol B和(6S)-2-methyl-6-(4-hydroxyphenyl-3-methyl)-2-hepten-4-one[16, 17]的结构相似, 其中化合物1与turmeronol B的区别在于: 苯环上的甲基取代位置可能不同, 化合物1苯环上C-4和C-5的化学位移与turmeronol B存在较大的差异; 而化合物1与(6S)-2-methyl-6-(4-hydroxyphenyl-3-methyl)-2-hepten-4-one的区别在于: 苯环上羟基的取代位置可能不同, 两者苯环上碳化学位移差异显著。
为了进一步确定化合物1的结构, 进行了2D NMR实验, 其主要HMBC和1H-1H COSY信号如图 1所示。在HMBC谱中, H-3与C-1、C-2、C-5相关, H-4与C-2、C-6相关, H-6与C-2、C-4相关, H3-15与C-4、C-6相关, OH-2与C-1、C-2、C-3相关, 结合1H-1H COSY中H-3/H-4的相关性, 证明化合物含有1个1, 2, 5-三取代苯环, 且C-2位被羟基取代, C-5位被甲基取代。根据HMBC谱中H3-14与C-1、C-7、C-8相关, H-7与C-1、C-2、C-6、C-8、C-9相关, H2-8与C-9相关, H-10与C-9、C-12、C-13相关的信号, 以及H3-14/H-7/H2-8的1H-1H COSY相关信号, 证明化合物含有1条如图 1所示的α, β-不饱和酮支链。综合以上信息, 化合物1的平面结构得以确定。
化合物1的绝对构型通过计算ECD确定。使用IEFPCM模型, 以乙腈为溶剂, 在CAM-B3LYP/DGDZVP水平计算(7S)-1和(7R)-1的理论ECD谱(图 2)。结果显示, 在200~340 nm波长下, 化合物的实测ECD谱与(7S)-1的理论ECD谱吻合。因此, 化合物1的绝对构型确定为7S。该新化合物命名为isoturmeronol B。
采用Griess法[18]评价化合物1对LPS诱导RAW 264.7细胞释放一氧化氮(NO) 的影响。结果表明, 阳性药姜黄素的IC50为9.83 ± 1.82 μmol·L-1, 化合物1在3.13、6.25、12.5、25和50 μmol·L-1时对NO的释放无明显抑制作用。
采用Shang等[19]的方法评价化合物1对2, 2-联苯基-1-苦基肼基(DPPH) 的影响。结果表明, 阳性药维生素C的IC50为19.63 ± 0.41 μmol·L-1, 化合物1在3.13、6.25、12.5、25和50 μmol·L-1时对DPPH无明显清除作用。
本研究对姜黄的化学成分进行了探索, 从中获得了1个结构新颖的倍半萜, 并通过质谱、核磁、计算ECD等手段确定该化合物的结构和绝对构型。化合物1的骨架类型在自然界中报道较少[16, 20, 21], 其与没药烷型倍半萜类似, 唯一的区别在于六元环上甲基的取代位置不同, 没药烷型倍半萜六元环上的甲基在C-4位, 而该骨架类型倍半萜六元环上的甲基在C-5位。姜黄含有的倍半萜种类丰富, 但目前为止, 该骨架类型的倍半萜仅从姜黄中分离得到过一个[16]。化合物1的发现丰富了姜黄的化学成分库, 有利于后续姜黄倍半萜类成分的研究。
现代药理学研究发现, 抗炎是没药烷型倍半萜的主要活性之一, Cheng等[22-24]从姜黄中分离得到的没药烷型倍半萜也表现出一定的抗炎活性。因来源相同且结构相似, 所以本研究考察了化合物1的抗炎活性。活性评价显示: 化合物1在3.13~50 μmol·L-1的浓度范围内对LPS诱导的RAW 264.7细胞释放NO无明显抑制作用, 因此猜测没药烷型倍半萜六元环上的甲基发生迁移后, 其抗炎活性可能会受到影响。此外, 因为化合物1具有1个酚羟基, 所以考察了化合物1的抗氧化活性。活性评价显示: 化合物1在3.13~50 μmol·L-1的浓度范围内对DPPH无明显清除作用, 可能是酚羟基的位置及其周围的取代基对抗氧化活性造成了影响。
