AIM
This study investigated the antifungal properties of aqueous extracts obtained from indigenous plants that grow spontaneously in the Northern Sahara of Algeria. The activities of these plants in controlling two fungal species that belong to genus were evaluated in an in vitro assay.
MATERIALS AND METHODS
Fresh aerial parts of four plant species (, and ) were collected for the preparation of aqueous extracts. Two levels of dilution (10% and 20%) of the pure extracts were evaluated against and .
RESULTS
The results of this study revealed that the , , and aqueous extracts are effective at both concentrations of 10% and 20% for the growth inhibition. In particular, extract is effective against , whereas mycelium growth is strongly affected by the 20% extract. The phytochemical characterization of the compositions of the aqueous extracts has revealed that the presence of some chemical compounds (tannins, flavonoids, saponins, steroids, and alkaloids) is likely to be responsible for the antifungal activities sought.
CONCLUSION
The antifungal properties of , , , and make these plants of potential interest for the control of fungi affecting both wheat yield and safety.
目的
本研究旨在探究生长在阿尔及利亚北部撒哈拉沙漠的几种本土植物的水提物的抗真菌特性。采用体外试验评估这些植物对两种真菌属的两种真菌种的控制活性。
材料和方法
采集了四种植物（、、和）的新鲜地上部分，以制备水提物。评估了纯提物的两个稀释度（10%和 20%）对和的作用。
结果
本研究结果表明，、、和的水提物在 10%和 20%的浓度下对的生长抑制均有效。特别是，提取物对有效，而 20%提取物强烈影响 的菌丝体生长。对水提物成分的植物化学特征分析表明，一些化合物（单宁、类黄酮、皂苷、类固醇和生物碱）的存在可能是所寻求的抗真菌活性的原因。
结论
、、和的抗真菌特性使这些植物具有控制影响小麦产量和安全的真菌的潜力。
