, commonly known (Aslooz) in Tunisia, is an annual plant, native to the North Africa and Middle East. species are used as food, their young leaves can be cooked, providing nutrients and health-giving phytochemicals such as phenolic compounds, polyphenols and carotenoids. Phytochemical composition and bioactivity of leaf extracts, collected from four different bioclimatic zones in Tunisia, are investigated in the present study. Results showed that location and climatic variations can alter the phytochemical composition of . Interestingly, HPLC analysis enabled identifying lutein and beta-carotene at high concentrations, especially in extracts of collected from Gabes (B2) (344 µg/g of lutein) and collected from Zarzis (B3) (1364 µg/g of beta-carotene). In particular, the antioxidant activity measured by DPPH assay showed that the extract of the plants collected from the growing region of Zarzis exhibits the highest antioxidant activities (0.99 mg/mL). All the extracts showed a relevant antiproliferative activity, especially toward the Caco-2 cell line. These preliminary data resulted in being useful to correlate growth environmental conditions with different accumulation of metabolites in Brassica species still being poorly studied.
在突尼斯通常被称为（阿斯洛兹），是一种一年生植物，原产于北非和中东。该物种被用作食物，其嫩叶可以烹饪，提供营养物质和具有健康益处的植物化学物质，如酚类化合物、多酚和类胡萝卜素。本研究调查了从突尼斯四个不同生物气候区采集的该植物叶片提取物的植物化学成分和生物活性。结果表明，地理位置和气候差异会改变该植物的植物化学成分。有趣的是，高效液相色谱分析能够鉴定出高浓度的叶黄素和β-胡萝卜素，特别是在从加贝斯（B2）采集的提取物中（叶黄素含量为344微克/克）以及从扎尔齐斯（B3）采集的提取物中（β-胡萝卜素含量为1364微克/克）。特别是，通过DPPH法测定的抗氧化活性表明，从扎尔齐斯种植区采集的植物提取物具有最高的抗氧化活性（0.99毫克/毫升）。所有该植物提取物均表现出相关的抗增殖活性，尤其是对Caco-2细胞系。这些初步数据有助于将生长环境条件与芸苔属物种中仍研究较少的不同代谢物积累相关联。
