Abstract

Two new triterpenoids, named gouanic acid A (1) and gouanic acid B (2), were isolated from the aerial parts of Gouania ulmifolia, along with six known compounds. The structures of the new compounds were determined by spectroscopic methods, mainly NMR (1D and 2D) and mass spectrometry. The new compounds did not show significant antimicrobial activities.

摘要

从榆叶山蚂蝗的地上部分分离出两种新的三萜类化合物，命名为钩叶酸A（1）和钩叶酸B（2），同时还分离出六种已知化合物。通过光谱方法，主要是核磁共振（一维和二维）和质谱法确定了新化合物的结构。新化合物没有显示出显著的抗菌活性。
