In order to better understand the chemical composition of the olive tree bark of Tunisian chemlali variety (Olea europaea cv. 'Chemlali'), this material was extracted by different ways. Compositions of extracts were used at best-selected conditions for each technique, and characterised using HPLC, LC/MS and GC-MS techniques. Analyses are conducted to an important variety of high carbon number compounds such as aliphatic compounds as nanocosane and heptacosane, and molecules with high value added tax (VAT) which can be classified as follows: diterpenes as phytol, triterpenes as squalene and also esters as Benzyl cinnamate. Hydrodistillation at high pressure seems to be a very common method to get a wide variety of compounds, the results are better than the ones obtained using supercritical fluid extraction and solvent extraction.
为了更好地了解突尼斯Chemlali品种（油橄榄cv. 'Chemlali'）橄榄树皮的化学成分，采用了不同方法对该材料进行提取。提取物的成分在每种技术的最佳选定条件下使用，并通过高效液相色谱（HPLC）、液相色谱/质谱联用（LC/MS）和气相色谱/质谱联用（GC-MS）技术进行表征。对多种高碳数化合物进行了分析，如作为纳米二十烷和二十七烷的脂肪族化合物，以及具有高附加值税（VAT）的分子，这些分子可分类如下：作为叶绿醇的二萜类、作为角鲨烯的三萜类以及作为肉桂酸苄酯的酯类。高压水蒸馏似乎是获得多种化合物的非常常见的方法，其结果优于使用超临界流体萃取和溶剂萃取所获得的结果。
