Essential oil from clove [Syzygium aromaticum (L.) Merr. Et Perry] buds was analyzed by GC-MS, and 20 components were identified. The main one was eugenol, which absolute content was 91.197mg/g. Antifungal activity assays showed that the oil and its derivant both inhibited the growth of Aspergillus niger and Penicillium expansun. The minimum inhibition concentration (MIC) of the oil was 50% for Aspergillus niger and 25% for Penicillium expansun, while that of the derivant was 25% for Aspergillus niger and 20% for Penicillium expansun. Both eugenol and its derivant also inhibited the growth of Aspergillus niger and Penicillium expansun, and the MIC of the eugenol was 1% for Aspergillus niger and 0.5% for Penicillium expansun, while that of the eugenol derivant was 5% for both Aspergillus niger and Penicillium expansun.%研究结果表明,丁香[Syzygium aromaticum (L.) Merr. et Perry]挥发油及其衍生物均可抑制黑曲霉(Aspergillus niger)和扩展青霉(Penicillium expansun)的生长,丁香挥发油对黑曲霉的最小抑菌浓度为50%,对扩展青霉的最小抑菌浓度为25%;丁香挥发油衍生物对黑曲霉的最小抑菌浓度为25%,对扩展青霉的最小抑菌浓度为20%.用GC-MS详细分析了丁香挥发油的化学成分,共鉴定了20个化合物,其中主要成分为丁香酚,含量占挥发油成分总量的68.0278%.
