Fourteen compounds including two new compounds were isolated from Kronopolites svenhedini (Verhoeff). These structures were identified as kronoponit A (1), kronoponit B (2), neoechinulin A (3), 2-(1, 1-dimethyl-2-propen-1-yl)-1H-indole-3-carboxaldehyde (4), uracil (5), p-hydroxy phenyl ethylamine (6), p-hydroxyphenylacetic acid (7), p-hydroxybenzoic acid (8), p-ethylbenzoic acid (9), 2-methyl-1, 4-benzenediol (10), 1, 2, 4-benzenetriol (11), gallic acid (12), gallic acid-3-methyl ether (13), and 4-methoxy-3, 5-hydroxybenzoic acid (14) by spectroscopic methods and literature. Among them, compounds 1 and 2 are new, while compounds 3-14 are reported here for the first time from K. svenhedini.

宽跗陇马陆[Kromopolites sevenhedini (Verhoeff)] 又名掸子虫、千足虫等, 是圆马陆科(Strongylosomidae) 陇马陆属(Kronopolites) 多足动物, 喜居于阴暗潮湿的环境, 多分布于我国甘肃临夏地区[1]。宽跗陇马陆药用历史悠久, 始载于《神农本草经》, 味辛性温, 具有治腹中大坚症, 破积聚、息肉、恶创、白秃的功效[2]。现代研究发现宽跗陇马陆主要化学成分为芳香酮类[3]、壳聚糖[4]、醌类、多肽和蛋白质、微量元素[5]等, 具有广谱抗癌[6]、抗炎[7]、抗菌[8]、提高免疫[9]等药理活性, 临床上用于治疗溃疡、胃溃疡和萎缩性胃炎[10, 11]等, 但总体上其化学成分的研究尚不充分。为进一步探索其化学成分, 本文采用多种色谱分离方法对宽跗陇马陆化学成分进行提取分离, 得到了14个化合物, 包括6个含氮化合物(1~6), 8个芳香化合物(7~14), 结构见图 1。其中12为新化合物, 3~14均为首次从马陆中分离得到的化合物。
化合物1为褐色胶状。根据HR-ESI-MS m/z 233.127 6 [M+H]+ (calcd. for 233.128 5, C13H17N2O2) 结合其核磁数据, 确定其分子式为C13H16N2O2, 不饱和度为7。1H NMR (500 MHz, CD3OD) 谱(表 1) 显示低场区有1个H信号[δH 7.24 (1H, s, H-6)], 中高场区有3个亚甲基信号[δH 4.40 (2H, t, J = 7.3 Hz, H-12), 3.37 (2H, t, J = 7.8 Hz, H-10), 2.91 (2H, m, H-11)], 3个甲基信号[δH 3.96 (3H, s, H-13), 3.83 (3H, s, H-14), 2.47 (3H, s, H-15)]。在13C NMR (150 MHz, CD3OD) 和DEPT谱(表 1) 中显示有13个碳原子, 6个非质子碳(芳香区或烯区) [δC 158.6 (C-2), 126.6 (C-4), 154.2 (C-5), 148.0 (C-7), 119.3 (C-8), 130.7 (C-9)], 1个次甲基[δC 94.4 (C-6)], 2个甲氧基[δC 56.9 (C-13), 61.3 (C-14)], 3个亚甲基[δC 24.7 (C-10), 26.7 (C-11), 47.0 (C-12)], 1个甲基[δC 10.4 (C-15)]。1H-1H COSY谱(图 2) 中H2-10/H2-11/H2-12的相关推断C-10-C-11-C-12片段的存在。HMBC谱(图 2) 中H2-10、H2-11/C-2相关, 可知C-10-C-11-C-12片段连接于C-2位。HMBC谱中H3-15/C-7、C-8、C-9和H-6/C-4、C-5、C-7、C-8、C-9的相关, 结合化学位移、分子式及不饱和度, 推测C-4、C-5、C-6、C-7、C-8、C-9依次连接组成了一个五取代苯环, 其中C-5、C-7连接了氧原子, C-4、C-9连接了N-3、N-1, C-15甲基连接于C-8位。HMBC谱中H3-13/C-5和H3-14/C-7的相关, 证明两个甲氧基分别连接于C-5和C-7。根据不饱和度和分子式可以推测出, C-2与N-1通过双键相连, 同时C-2与N-3通过单键相连, C-12与N-3相连, 即N-1、C-2、N-3、C-4、C-9依次连接形成一个2-吡唑啉环。综上所述, 确定化合物1的结构如图 1所示, 命名为kronoponit A。
化合物2为红色胶状。根据HR-ESI-MS m/z 248.090 7 [M+H]+ (calcd. for 248.091 7, C13H14NO4) 结合其核磁数据, 确定其分子式为C13H13NO4, 不饱和度为8。1H NMR (500 MHz, DMSO-d6) 谱(表 1) 显示低场区有3个H信号[δH 7.39 (1H, s, H-8), 6.66 (2H, s, 3-NH2)], 中高场区有3个甲基信号[δH 3.71 (3H, s, H-11), 2.52 (3H, s, H-10), 1.83 (3H, s, H-9)]。在13C NMR (150 MHz, DMSO-d6) 和DEPT谱(表 1) 中显示有13个碳原子, 9个非质子碳[δC 180.8 (C-1), 107.9 (C-2), 148.2 (C-3), 181.4 (C-4), 120.7 (C-4a), 135.1 (C-5), 148.3 (C-6), 155.0 (C-7), 132.3 (C-8a)], 1个次甲基[δC 112.4 (C-8)], 1个甲氧基[δC 59.8 (C-11)], 2个甲基[δC 9.4 (C-9), 13.8 (C-10)]。HMBC谱中H3-10/C-6、C-5、C-4a、C-4, H-8/C-6、C-7、C-8a、C-4a、C-1和H3-9/C-1、C-2、C-3的相关, 结合化学位移、分子式及不饱和度, 推定其母核为α-(1, 4) 萘醌; 其中C-5被甲基C-10取代, C-2被甲基C-9取代, C-7被羟基取代。HMBC谱中H3-11/C-6的相关确定一个甲氧基连接于C-6位。HMBC谱中3-NH2/C-2、C-3、C-4的相关确定存在一个氨基位于C-3位。综上所述, 确定化合物2的结构如图 1所示, 命名为kronoponit B。
