Abstract

Six new iridoid glucosides, caudatosides A-F (2-7), and one known iridoid glucoside, 5-deoxypulchelloside I (1), were isolated from the fruits of Citharexylum caudatum. The structures of these compounds were elucidated by various one- and two-dimensional NMR techniques as well as high-resolution negative-ion ESIMS. Other plant parts were extracted on a small scale, and TLC of these extracts revealed the presence of the same iridoids.

摘要

从尾叶琴木（Citharexylum caudatum）的果实中分离出6种新的环烯醚萜苷，即尾叶苷A - F（2 - 7），以及1种已知的环烯醚萜苷，5 - 脱氧普氏苷I（1）。通过各种一维和二维核磁共振技术以及高分辨率负离子电喷雾电离质谱（ESIMS）阐明了这些化合物的结构。对该植物的其他部位进行了小规模提取，这些提取物的薄层色谱（TLC）显示存在相同的环烯醚萜类化合物。
