Effect of some of plant extracts on the growth of two Aspergillus species

Background & Aim: In recent years using from plant product has been considered wildly as main factor for preventing pathogenic diseases cassed by attacking viruses, bacteria, fungi and parasites. There are some funguses which could be the factors for affliction of some diseases in human, plants and animals. Plant extracts are those which could act and be used as preventing from these diseases as product of opposed fungus. The main aim of this article is considering the effects of Anethum graveolens, Thymus vulgaris, Coriandrum sativum and Rosa damascena is on standard strains and separated as Aspergillus flavus and Aspergillus fumigatus.                                                                                                          Experimental: The sink was used for preventing the development of plant extract and not growing different density of extract were considered separately. The minimum inhibitory concentration (MIC) was calculated by the serial diluted method. Results & Discussion: The result showed that Aspergillus flavus standard (PTCC 5006), nystatin and extracts of A. graveolens, C. sativum and T. vulgaris in equal amount and finally R. damascena had more effects in opposed fungus. About separated strain of this fungus from the environment, nystatin, T. vulgaris, A. graveolens, C. sativum and finally R. damascena had the most effect against fungus. About standard Aspergillus fumigatus (PTCC 5009), the most effective mixtures against fungus were included extracts of A. graveolens, R. damascena, and C. sativum respectively. About separated strain of this fungus until the most effective mixture of opposed fungus respectively were including nystatin, A. graveolens, T. vulgaris, C. sativum and finally R. damascena. The result of this investigation shows that the existence extracts will be the main cause of reducing the growth of fungi. In this case by increasing the extracts of A. graveolens, T. vulgaris, C. sativum and R. damascena will be increased. Industrial/Practical recommendation: By proving the effect distributing the extracts leaves of Anethum graveolens, Thymus vulgaris, Coriandrum sativum and Rosa damascena on growing of two kinds of Aspergillus containing as Aspergillus flavus and Aspergillus fumigatus, there will be a hope that in future, by delivering the effective substances of above plants, and doing more experiment and investigation we would be able to reach an acceptable effects and having less side effect and complications for curing fungus infection diseases.
