Study on Inhibitory Effect of Volatile Oils in 16 Plants on Aspergillus flavus of Platycladi Semen
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:
2
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:
2
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:
2
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.
