The effect of methanolic and aqueous extracts of bilberry leaves on the growth of Aspergillus flavus and on its ability to synthesize aflatoxins was studied. Both extracts could inhibit aflatoxins’ biosynthesis by A. flavus grown in either a rich or minimal media. Aqueous extracts were more efficient, at totally inhibiting aflatoxins biosynthesis at ~2.8 and 2.2 mg/ml for aflatoxins B1 and B2, respectively, in rich medium, whereas in minimal medium the respective values were 625 and 313 μg/ml. Methanolic extracts were less efficient, as they did not completely inhibit the biosynthesis even at higher concentrations of the extract. The results suggested that bilberry leaves may contain substances that can be used as natural food additives.

研究了越橘叶片的甲醇和水提物对黄曲霉生长及其合成黄曲霉毒素的能力的影响。两种提取物可以通过抑制黄曲霉素的生物合成黄曲霉在任何一个富或基本培养基中生长。在富含培养基中，黄曲霉毒素B1和B2的水提取物更能有效地分别抑制黄曲霉毒素B1和B2的黄曲霉毒素生物合成，分别为2.8和2.2 mg / ml，而在最小培养基中，黄曲霉毒素的合成值为625和313μg/ ml。甲醇提取物效率较低，因为即使在提取物浓度较高时，它们也不能完全抑制生物合成。结果表明，越桔叶可能含有可用作天然食品添加剂的物质。
