ABSTRACT
Objective::To select volatile oils from 16 species of plants (Cymbopogon citratus, Pelargonium graveolens, Pinus tabulieformis, Litsea cubeba, Mentha haplocalyx, Zingiber officinale, Syzygium aromaticum, Curcuma longa, Zanthoxylum bungeanum, Cinnamomum cassia, Ocimum basilicum, Rosmarinus officinalis, Zanthoxylum schinifolium, Zanthoxylum armatum, Illicium verum, Myristica fragrans) that have good inhibitory effect on the growth of Aspergillus flavus. Method::Aspergillus flavus was isolated from the surface of Platycladi Semen medicinal materials by plate culture method. The volatile oils of 16 plants were extracted by steam distillation. The colony diameter of Aspergillus flavus was determined by fumigation of filter paper, and the effect of volatile oils on the growth of Aspergillus flavus was systematically studied. Result::Aspergillus flavus was successfully isolated from Platycladi Semen by means of morphological, microscopic and DNA barcoding identification methods, the bacteriostatic rates of the above 16 kinds of volatile oils against Aspergillus flavus were 2.93%, 0.05%, 0.37%, 76.07%, 0.34%, 0.15%, 50.05%, 8.51%, 1.43%, 58.20%, 0.07%, 2.60%, 8.73%, 100.00%, 52.62%, 0.07%, respectively. Conclusion::The volatile oils of 16 plants all have different degrees of antibacterial activities for Aspergillus flavus, and volatile oils of Zanthoxylum armatum, Litsea cubeba and Cinnamomum cassia have good inhibitory effect. This study can provide a theoretical basis for the prevention and control of Aspergillus flavus in the growth and storage of Platycladi Semen, and provide a basis for further research on plant volatile oil as bacteriostatic agents in the storage process of traditional Chinese medicine.
