Abstract

Two unusual monoterpene indole alkaloids, stachyoside (1) and nor-methyl-23-oxo-correantoside (2), have been isolated from the aerial parts of Psychotria stachyoides. The structural elucidation of both compounds was performed by the aid of HRESIMS, FT-IR, and 1D- and 2D-NMR techniques including COSY, HSQC, HMBC, and NOESY.

摘要

从Psychotria stachyoides 的地上部分分离得到了两种不常见的单萜吲哚生物碱：stachyoside（1）和 nor-methyl-23-oxo-correantoside（2）。通过高分辨质谱（HRESIMS）、傅里叶变换红外光谱（FT-IR）以及包括 COSY、HSQC、HMBC 和 NOESY 在内的 1D 和 2D-NMR 技术，确定了这两种化合物的结构。
