Abstract

From the methanol extract of the stem bark of Scaphopetalum thonneri, two new compounds, including one lignan, named scaphopetalone, one new ester of ferulic acid, named scaphopetalumate were isolated together with three known compounds including: two coumarins (scopoletin and scopolin), and one pentacyclic triterpene (oleanolic acid). The structure of the new compounds were elucidated by means of spectroscopic analyses.

摘要

从舟瓣芹茎皮的甲醇提取物中，分离出两种新化合物，其中一种为木脂素，命名为舟瓣芹素，另一种为阿魏酸新酯，命名为舟瓣芹酸酯，同时还分离出三种已知化合物，包括两种香豆素（东莨菪亭和东莨菪苷）以及一种五环三萜（齐墩果酸）。通过光谱分析确定了新化合物的结构。
