Abstract

The chemical study of from South-East Algeria led to the isolation of twelve oxygenated terpenoid compounds, including three new pentacyclic triterpenoids - with either lupane or ursane rearranged skeletons. The structure and the stereochemistry of these compounds were established by spectroscopic methods, including NMR techniques. The chemical pattern of is in accordance with the triterpenoid scenario of the genus embracing to date lupane, oleane, ursane and taraxastane skeletons. However, the carbon frameworks exhibited by new compounds - have never been reported from species.

摘要

从阿尔及利亚东南部采集的进行了化学研究，从中分离出了 12 种含氧萜类化合物，其中包括 3 种新的五环三萜 - 具有羽扇烷或熊烷骨架重排。这些化合物的结构和立体化学通过包括 NMR 技术在内的光谱方法确定。的化学模式符合迄今已知的属三萜类化合物的情况，包括羽扇烷、齐墩果烷、熊烷和蒲公英烷骨架。然而，新化合物所表现出的碳骨架 - 从未在种中报道过。
