is a cosmopolitan saprophytic fungus that infests several foodstuffs and is associated with adverse effects in humans. In Senegal, significant losses of groundnut production are mainly due to contamination caused by this species. This study evaluated in vitro antifungal activities of , and essential oils against isolated from peanut seeds. Essential oils obtained by hydrodistillation of rhizomes of the two species and leaves of were analyzed with GC-DIF and GC-MS. The essential oil yields from , and were 1.1%, 1.3% and 1.7%, respectively. These three samples had the following chemotypes: (i) mustakone (21.4%)/eudesma-4(15)-7-dien-1β-ol (8.8%)/caryophyllene oxide (5.9%), (ii) caryophyllene oxide (25.2%)/humulene epoxyde 2 (35.0%) and (iii) geranial (46.6%)/neral (34.6%). The three oils tested inhibited the growth of at concentrations between 100 and 1000 ppm. The oil was the most effective with total clearance of on PDA. For the essential oils of (93.65%) and (78.11%), the highest inhibition rates were obtained with a 1000 ppm dose. Thus, oil could be used safely as an effective protector of groundnuts against .
是一种世界性的腐生真菌，它侵染多种食品，并与对人类的不良影响有关。在塞内加尔，花生产量的大幅损失主要是由于该物种造成的污染。本研究评估了[具体植物1]、[具体植物2]和[具体植物3]精油对从花生种子中分离出的[目标真菌名称]的体外抗真菌活性。对通过水蒸馏两种[具体植物1]物种的根茎和[具体植物3]的叶子获得的精油进行了气相色谱 - 二极管阵列检测（GC - DIF）和气相色谱 - 质谱联用（GC - MS）分析。[具体植物1]、[具体植物2]和[具体植物3]的精油产量分别为1.1%、1.3%和1.7%。这三个样品具有以下化学类型：（i）麝香草酮（21.4%）/桉叶 - 4(15) - 7 - 二烯 - 1β - 醇（8.8%）/氧化石竹烯（5.9%），（ii）氧化石竹烯（25.2%）/环氧葎草烯2（35.0%），以及（iii）香叶醛（46.6%）/橙花醛（34.6%）。测试的三种油在100至1000 ppm的浓度下抑制了[目标真菌名称]的生长。[具体植物3]油最有效，在马铃薯葡萄糖琼脂（PDA）上完全清除了[目标真菌名称]。对于[具体植物1]（93.65%）和[具体植物2]（78.11%）的精油，在1000 ppm剂量下获得了最高抑制率。因此，[具体植物3]油可以安全地用作花生对抗[目标真菌名称]的有效保护剂。
