Propolis ethanolic extract (PEE) at 3 and 4 g/L and ultragriseofulvin (UG) at 0.75 and 1 g/L reduced the percentage of conidia germination in two Aspergillus flavus isolates. PEE at 1-4 g/L decreased the mycelial dry mass of A. flavus isolates by 11-80%, and aflatoxin B1 production by 34-100%. UG concentrations of 0.25-1 g/L reduced the growth and aflatoxin B1 production of the isolates by 16-88 and 48-98%, respectively. Any increase in PEE and UG concentration was accompanied by a clear decrease in the per cent conidia germination, growth and aflatoxin B1 production. At equal concentration, UG was about 4-times more effective than PEE.
浓度为3克/升和4克/升的蜂胶乙醇提取物（PEE）以及浓度为0.75克/升和1克/升的超灰黄霉素（UG）降低了两株黄曲霉分离株中分生孢子的萌发率。浓度为1 - 4克/升的PEE使黄曲霉分离株的菌丝体干质量减少了11% - 80%，黄曲霉毒素B1的产量减少了34% - 100%。浓度为0.25 - 1克/升的UG分别使分离株的生长和黄曲霉毒素B1产量降低了16% - 88%和48% - 98%。PEE和UG浓度的任何增加都伴随着分生孢子萌发率、生长和黄曲霉毒素B1产量的明显降低。在相同浓度下，UG的效果约为PEE的4倍。
