Cuminum cyminum L. (Cumin) is a flavoring agent that is commonly used worldwide, and is rich in essential oil. Essential oils (Eos) have been intensively investigated in regard to their potential for disease control in plants, which is provided a chance for the blossom of green pesticides. The chemical components of Cumin essential oil (CEO) were revealed by GC/MS, such as cuminaldehyde (44.53 %), p-cymene (12.14 %), (−)-β-pinene (10.47 %) and γ-terpinene (8.40 %), and found they can inhibit the growth of P. notoginseng-associated pathogenic fungi in vitro and the inhibitory effect of cuminaldehyde was similar to that of hymexazol. SEM and TEM images demonstrated that cuminaldehyde and CEO increased cell permeability and disrupted membrane integrity. The expression of disease-related genes of Fusarium oxysporum showed that CEO induced the expression of most genes, which disrupted biosynthesis, metabolism and signaling pathways. These studies verified the potential of CEO as a plant fungicide that is environmentally friendly and provided ideas for developing new products for controlling root diseases that affect P. notoginseng.

大茴香精油的化学成分及其对三七病原体的抗真菌活性

Cuminum cyminum L.（孜然）是一种世界范围内普遍使用的调味剂，富含精油。精油（Eos）在植物病害防治方面的潜力得到了深入研究，这为绿色农药的开花提供了机会。GC/MS 揭示了孜然精油 (CEO) 的化学成分，如孜然醛 (44.53 %)、对伞花烃 (12.14 %)、(-)- β-蒎烯 (10.47 %) 和γ-松油烯 (8.40 %)，发现它们可以抑制三七的生长体外相关病原真菌和异丙苯醛的抑制作用与恶霉灵相似。SEM 和 TEM 图像表明，孜然醛和 CEO 增加了细胞通透性并破坏了膜的完整性。尖孢镰刀菌疾病相关基因的表达表明，CEO诱导了大多数基因的表达，从而破坏了生物合成、代谢和信号通路。这些研究证实了 CEO 作为一种环境友好型植物杀菌剂的潜力，并为开发新产品以控制影响三七的根部病害提供了思路。
