宽跗陇马陆中2个新含氮化合物的分离鉴定

Isolation and identification of two new nitrogen-containing compounds from Kronopolites svenhedini (Verhoeff)

摘要: 利用各种色谱技术从宽跗陇马陆Kronopolites svenhedini (Verhoeff) 中分离得到了14个化合物。结合波谱学方法和文献鉴定其结构, 分别为kronoponit A (1)、kronoponit B (2)、neoechinulin A (3)、2-(1, 1-dimethyl-2-propen-1-yl)-1H-indole-3-carboxaldehyde (4)、尿嘧啶(5)、对羟基苯乙胺(6)、对羟基苯乙酸(7)、对羟基苯甲酸(8)、对乙基苯甲酸(9)、2-甲基-1, 4-苯二酚(10)、1, 2, 4-苯三酚(11)、没食子酸(12)、没食子酸-3-甲基醚(13) 和4-甲氧基-3, 5-羟基苯甲酸(14)。其中, 1和2为新化合物, 3~14为首次从马陆中分到的化合物。

Abstract: 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.
