Fungicidal Activity of Essential Oils from Cinnamomum cassia against the Pathogenic Fungi of Panax notoginseng Diseases.

Fungicidal Activity of Essential Oils from Cinnamomum cassia against the Pathogenic Fungi of Panax notoginseng Diseases. Chem Biodivers. 2019 Oct 21;: Authors: Ma YN, Chen CJ, Li Q, Wang W, Xu FR, Cheng YX, Dong X Abstract The frequent disease of Panax notoginseng caused by the pathogenic fungi in field cultivation has become the major threaten to the sustainable development of it. The present study was conducted to find natural agent with potential inhibition against pathogen. Therefore, the inhibitory effects of Cinnamomum cassia (L.) J.Presl essential oils (EOs) against P. notoginseng associated pathogenic fungi were conducted both in vitro and in vivo experiments. The results of the Oxford cup test revealed that C. cassia dry bark EO (50 mg/mL) had significant inhibitory activity on the growth of all tested fungi, and the growth of various pathogens was completely inhibited, except for that of Fusarium solani. Therefore, the constituents of C. cassia EOs were analyzed by GC/MS, and the research demonstrated that the main constituents of C. cassia dry bark EO were trans-cinnamaldehyde (75.65 %), (E)-2-methoxycinnamaldehyde (6.08 %), cinnamaldehyde (3.47 %) and cinnamyl acetate (1.02 %). The MIC results showed that C. cassia dry bark EO and the main compounds had good antifungal effect on the tested strains, and the inhibitory effect was similar to that of hymexazol (chemical pesticide). By analyzing the value of the ...
