从菝葜试管的 70% EtOH 提取物的 BuOH 级分中分离出两种新的甾体皂苷（1 和 2），以及四种已知的类似物 3-6。通过化学证据和光谱分析，包括 HR-MS、IR、H-1- 和 C-13-NMR 以及 2D 实验（H-1-H-1 COSY、HSQC 和 HMBC），阐明了新化合物的结构。版权所有 (C) 2009 John Wiley & Sons, Ltd.
Two new steroidal saponins (1 and 2) were isolated from the BuOH fraction of the 70% EtOH extract of the tubes of Smilax china, together with four known analogues, 3-6. The structures of the new compounds were elucidated by means of chemical evidence and spectroscopic analyses, including HR-MS, IR, H-1- and C-13-NMR, and 2D experiments (H-1-H-1 COSY, HSQC and HMBC).
