Natural plant-derived compounds have been recognized as promising fungicides for reducing Aspergillus flavus growth in agricultural commodities. In this study, the synergistic antifungal activity of plant-derived compounds against A. flavus growth in stored pistachios was investigated. The minimum inhibitory concentration (MIC) of lauraldehyde, geraniol, dihydrocoumarin, and p-anisaldehyde against A. flavus in potato dextrose broth (PDB) were 0.40, 0.20, 0.40, and 0.80 mg/mL, respectively. Whereas, after screening 6 groups of agents using the checkerboard method, only one combination, i.e., that of lauraldehyde and geraniol (S_LG), showed synergistic effect (fractional inhibitory concentration index = 0.5) on A. flavus. In addition, at 2 MIC, S_LG completely inhibited the spore germination of A. flavus, colony radial growth, and aflatoxin biosynthesis. At the same time, the mycelial growth was inhibited by more than 98%. Further research found that fumigation with S_LG significantly inhibited the growth of A. flavus in stored pistachios and reduced aflatoxin biosynthesis. Moreover, the pistachios with S_LG fumigation exhibited higher soluble protein content, lower malonaldehyde (MDA) content, and lower carbonyl values, indicating that fumigation with S_LG could effectively delay the trend of quality deterioration in stored pistachios. These results supported S_LG as a potential green antifungal agent for the shelf-life extension of stored pistachios.

天然植物源化合物已被认为是有前途的杀菌剂，可减少农产品中黄曲霉的生长。在这项研究中，研究了植物源化合物对储存开心果中黄曲霉生长的协同抗真菌活性。马铃薯葡萄糖肉汤 (PDB) 中月桂醛、香叶醇、二氢香豆素和对茴香醛对黄曲霉的最低抑菌浓度 (MIC)分别为 0.40、0.20、0.40 和 0.80 mg/mL。而用棋盘法筛选了6组药剂后，只有一种组合，即月桂醛和香叶醇的组合（S _LG），对黄曲霉表现出协同效应（分数抑制浓度指数 = 0.5）。此外，在2 MIC时，SLG_完全抑制黄曲霉孢子萌发、菌落径向生长和黄曲霉毒素生物合成。同时，菌丝生长被抑制98%以上。_{进一步研究发现， SLG}熏蒸可显着抑制贮藏开心果中黄曲霉的生长，并减少黄曲霉毒素的生物合成。此外，经S _LG熏蒸的开心果表现出较高的可溶性蛋白含量、较低的丙二醛（MDA）含量和较低的羰基值，表明经S _{LG熏蒸的开心果}可有效延缓贮藏开心果品质恶化的趋势。这些结果支持 S _LG作为一种潜在的绿色抗真菌剂，可延长储存开心果的保质期。
