The study aimed to analyze the effects of extracts made from buckwheat grain, hulls, and bee products (propolis, bread, and pollen) and extraction solvents on the growth of microfungi on a medium and on buckwheat, wheat, oat, and maize grain. Research findings suggest that bioactive compounds contained in buckwheat grain reduced the amount of Fusarium spp. in the grain kept in the antifungal extract for 90 min at 25°C temperature. Buckwheat hull extract was more effective in inhibiting mycelial growth of mycotoxin‐producing Fusarium culmorum and Fusarium graminearum compared with buckwheat grain extract (13%–50% and 14%–36%, respectively). The antifungal activity of extracts of bee products did not depend on the content of phenolic compounds in them; however, it depended on the grain species treated. After treatment of oat, wheat, and maize grain with bee product extracts, the lowest concentration of microfungi was identified on oat grain. More significant analysis results were obtained for the samples where ethanol solvent had been used for the preparation of extracts.

抗真菌提取物对谷物受微真菌污染的作用。
这项研究旨在分析荞麦谷物，船体和蜂产品（蜂胶，面包和花粉）制成的提取物以及提取溶剂对中等真菌以及荞麦，小麦，燕麦和玉米谷物上微真菌生长的影响。研究发现表明，荞麦籽粒中含有的生物活性化合物减少了镰刀菌的数量。在25°C温度下90％保留在抗真菌提取物中的谷物中的维生素B. 荞麦壳提取物在抑制产生霉菌毒素的镰刀菌和禾谷镰刀菌的菌丝生长方面更有效与荞麦谷物提取物相比（分别为13％–50％和14％–36％）。蜂产品提取物的抗真菌活性不取决于其中酚类化合物的含量。但是，这取决于所处理的谷物种类。用蜂产品提取物处理燕麦，小麦和玉米籽粒后，在燕麦籽粒上发现了最低的微真菌含量。对于已经使用乙醇溶剂制备提取物的样品，获得了更有意义的分析结果。
