In continuation of our ongoing study on Mediterranean Flora, we focused the attention on Cistus genus. These plants possess interesting secondary metabolites and are used in many fields, principally in perfumery and more recently as raw material for food supplements (botanicals). n this article, we report the phytochemical analysis of Cistus libanotis L. from Tunisia. Among the diterpenes, labdane compounds resulted absent, in favour of two clerodanes, one of that never reported in Cistus sp. The main representative compounds were found to be several flavonoids with various grades of O-methylation. Other interesting components were two cinnamic esters of borneol, reported here for the first time in Cistus. The identified compounds confirm in part the reported biological properties and add chemotaxonomic data to this complicated genus.
在我们正在进行的地中海植物群研究中，我们将注意力集中在岩蔷薇属植物上。这些植物含有有趣的次生代谢产物，并在许多领域有应用，主要用于香水制造业，最近还用作食品补充剂（植物提取物）的原料。在本文中，我们报告了来自突尼斯的黎巴嫩岩蔷薇的植物化学分析结果。在二萜类化合物中，半日花烷型化合物未被发现，取而代之的是两种克罗烷型化合物，其中一种在岩蔷薇属植物中从未有过报道。主要的代表性化合物是几种具有不同程度O - 甲基化的黄酮类化合物。其他有趣的成分是两种冰片肉桂酸酯，这是首次在岩蔷薇属植物中报道。所鉴定出的化合物部分证实了已报道的生物学特性，并为这个复杂的属增加了化学分类学数据。
