Polyphenols, flavonoids and condensed tannins contents, as well as the antioxidant activity of the ethanolic and aqueous extracts obtained from aerial parts of 10 wild Tunisian plants, have been determined. Extracts showed appreciable levels of polyphenols and flavonoids, which reached 215.16 mg GAE g DW in Lavandula stoechas ethanolic extract, and 49.12 mg RE g DW in Thapsia garganica aqueous extract. The majority of tested extracts exhibited low total condensed tannins content, except for Rhus tripartitum and Periploca laevigata. The antioxidant activity tests showed great activity, especially for R. tripartitum and Lavandula multifida (IC = 5.16 and 5.1 μg mL, respectively). Canonical Correspondence Analysis revealed clear groupings of species according to the solvent used.
已测定了从10种突尼斯野生植物地上部分获得的乙醇提取物和水提取物中的多酚、黄酮类化合物和缩合单宁含量，以及抗氧化活性。提取物显示出可观的多酚和黄酮类化合物含量，其中薰衣草乙醇提取物中的含量达到215.16毫克没食子酸当量/克干重，刺山柑水提取物中的含量达到49.12毫克芦丁当量/克干重。除了三叶漆和光叶杠柳外，大多数测试提取物的总缩合单宁含量较低。抗氧化活性测试显示出很强的活性，尤其是三叶漆和羽叶薰衣草（IC50分别为5.16和5.1微克/毫升）。典范对应分析揭示了根据所用溶剂对物种进行的清晰分组。
