Abstract

Chromatographic fractionation of the chloroform extracts from the stem bark and stems of Guettarda grazielae resulted in the isolation of a new iridoid (guettardodiol, 1) and the secoiridoid sarracenin (2), described for the first time in this genus. The structural elucidation of these compounds was based on spectroscopic analyses (IR, MS as well as 1-D and 2-D NMR experiments).

摘要

从吉特达格拉泽尔茎皮和茎的氯仿提取物中进行色谱分离，得到了一个新的裂环环烯醚萜（吉特达二醇，1）和新的裂环环烯醚萜苷（2），这是在该属中首次描述的。这些化合物的结构阐明基于光谱分析（IR、MS 以及 1D 和 2D NMR 实验）。
