Two new sesquiterpenes, epi-guaidiol A (1) and sugebiol (3), together with four known sesquiterpenes, guaidiol A(2), sugetriol triacetate (4), cyperenoic acid (5), and cyperotundone (6) were isolated from the rhizomes of Cyperus rotundus L. Their structures were identified by MS and NMR experiments, and the complete assignments of (1)H and (13)C NMR data for two new sesquiterpenes were obtained by the aid of two-dimensional (2D) NMR techniques, including HSQC, HMBC, (1)H-(1)HCOSY and nuclear overhauser enhancement spectroscopy(NOESY).
从香附子的根茎中分离出两种新的倍半萜类化合物，表愈创木薁醇A（1）和苏格比醇（3），以及四种已知的倍半萜类化合物，愈创木薁醇A（2）、苏格三醇三乙酸酯（4）、香附子烯酸（5）和香附子酮（6）。通过质谱和核磁共振实验确定了它们的结构，并借助二维（2D）核磁共振技术，包括异核单量子相干谱（HSQC）、异核多键相关谱（HMBC）、氢-氢化学位移相关谱（1H-1HCOSY）和核Overhauser效应谱（NOESY），完成了两种新倍半萜类化合物的氢谱（1H）和碳谱（13C）核磁共振数据的全归属。
