Crude extracts from a medicinal Tunisian plant, L., were the investigated natural material. Butanolic extract of roots analyzed with IR spectra revealed the presence of hydroxyl, alcoholic, and carboxylic groups and sugars units. Analysis of some secondary metabolites, total phenolic, flavonoids, flavonols, and procyanidins, was performed using different solvents following the increased gradient of polarity. Fruits and leaves contained the highest amounts of all these compounds. Antioxidant properties were evaluated by the determination of free radical scavenging activity and the reducing power of methanolic extracts. Fruits and leaf extracts were the most powerful antioxidants for the two-assay in vitro system. Stems and fruits extracts exhibit an antifungal activity against which could become an alternative to synthetic fungicide to control species fungal diseases.
来自突尼斯一种药用植物L.的粗提物是所研究的天然材料。用红外光谱分析的根丁醇提取物显示存在羟基、醇基、羧基和糖类单元。按照极性增加的梯度，使用不同溶剂对一些次生代谢物、总酚、黄酮类化合物、黄酮醇和原花青素进行了分析。果实和叶子中这些化合物的含量最高。通过测定自由基清除活性和甲醇提取物的还原能力来评估抗氧化性能。在体外双测定系统中，果实和叶子提取物是最强的抗氧化剂。茎和果实提取物对……表现出抗真菌活性，这可能成为控制……物种真菌病害的合成杀菌剂的替代品。
