Plants are one of a prefect source of natural effective compounds that have antimicrobial, and other activities. This study investigated the activity of the aqueous extract for three wild edible plants (, and ) at three concentrations (1.5, 2.5 and 5 mg/ml) as antifungal and antitoxigenic. Many functional groups such as alcohols, phenols, alkanes and alkenes, etc were appeared in aqueous extracts by Fourier Transform Infrared Spectroscopy (FTIR) analysis. Where an extract of gave a greater total phenolic and flavonoids were 210.4 ± 1.15 and 36.7 ± 0.79 mg/mL, respectively, followed by (192.3 ± 2.11 mg/mL) and (186.4 ± 2.18 mg/mL). The results indicated that increasing the concentration of the extract, the area of inhibition zone increased with all treatments, where the highest inhibition zone was observed using 5 mg/ml for extract was 17.1 ± 1.7, 26.5 ± 1.5 and 22.8.±2.3 mm against and , respectively, while the lowest antifungal activity was marked with extract with all tested fungi. The results have also indicated that the aqueous extract has inhibited formed of aflatoxin B (AFB) and ochratoxin A (OTA), where the percentages of inhibition AFB were 78.03, 68.8 and 81.7% after treated yeast extract sucrose (YES) media by 5 mg crude extract for extract and , respectively. In contrast, the inhibitory effect against OTA at the same concentration was 77.5, 72.3, and 85.2% in the same order for plants. Finally, these plants provide an aqueous extract that contains many effective compounds that enable to play the role of antifungal and antitoxigenic
植物是具有抗菌和其他活性的天然有效化合物的完美来源之一。本研究调查了三种野生可食用植物（、和）的水提取物在三种浓度（1.5、2.5和5毫克/毫升）下的抗真菌和抗产毒活性。通过傅里叶变换红外光谱（FTIR）分析，水提取物中出现了许多官能团，如醇类、酚类、烷烃和烯烃等。其中提取物的总酚和黄酮含量分别为210.4±1.15和36.7±0.79毫克/毫升，其次是（192.3±2.11毫克/毫升）和（186.4±2.18毫克/毫升）。结果表明，随着提取物浓度的增加，所有处理的抑菌圈面积均增大，其中提取物在5毫克/毫升时对和的抑菌圈最大，分别为17.1±1.7、26.5±1.5和22.8±2.3毫米，而提取物对所有测试真菌的抗真菌活性最低。结果还表明，水提取物抑制了黄曲霉毒素B（AFB）和赭曲霉毒素A（OTA）的形成，在用5毫克粗提取物处理酵母提取物蔗糖（YES）培养基后，提取物和对AFB的抑制率分别为78.03%、68.8%和81.7%。相比之下，相同浓度下对OTA的抑制作用在这三种植物中依次为77.5%、72.3%和85.2%。最后，这些植物提供了一种含有许多有效化合物的水提取物，能够发挥抗真菌和抗产毒的作用 。
