Abstract

The assignments of 1H and 13C NMR spectra of two new aminoacyl triterpene saponins from roots of Gypsophila trichotoma Wend. are reported. In addition to 1D NMR methods, 2D NMR techniques (COSY, TOCSY, ROESY, HSQC, HMBC, and HSQC-TOCSY) were used for the assignments. The structures were completed by analysis of HR-ESI-MS and ESI-MS(n).

摘要

报道了来自毛叶丝石竹根中两种新的氨基酰基三萜皂苷的¹H和¹³C NMR光谱归属。除了一维NMR方法外，还使用二维NMR技术（COSY、TOCSY、ROESY、HSQC、HMBC和HSQC-TOCSY）进行归属。通过高分辨电喷雾电离质谱（HR-ESI-MS）和电喷雾电离多级质谱（ESI-MS(n)）分析确定了结构。
