chemical and biological characteristics of Cuminum Cyminum and rosmarinus officinalis essential oils
Food Chemistry, 2007Co-Authors: Latif Gachkar, Davood Yadegari, Mohammad Bagher Rezaei, Masood Taghizadeh, Shakiba Darvish Alipoor Astaneh, Iraj RasooliAbstract:Abstract Essential oils extracted by hydrodistillation from Cuminum Cyminum and Rosmarinus officinalis were characterized by means of GC and GC–MS. C. Cyminum and R. officinalis contained α-pinene (29.1%, 14.9%), 1,8-cineole (17.9%, 7.43%) and linalool (10.4%, 14.9%), respectively, as the major compounds. C. Cyminum oil exhibited stronger antimicrobial activity than did R. officinalis oil against E. coli, S. aureus and L. monocytogenes. Complete death time on exposure to Cuminum Cyminum L. and Rosmarinus officinalis L. oils were 20 and 25 min 180 and 240 min and 90 and 120 min for E. coli, S. aureus and L. monocytogenes, respectively. Radical-scavenging and antioxidant properties were tested by means of 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay and the β-carotene bleaching test. These properties were compared to those of Thymus x-porlock essential oil, used as a reference ingredient. The radical scavenging performance of the rosemary oil was better than that of C. Cyminum. Results from the antioxidant test were better than those provided by the radical-scavenging activity. C. Cyminum and R. officinalis essential oils may be considered as potent agents in food preservation.

The antibacterial effects of Cuminum Cyminum L. and Rosmarinus officinalis extracts and essential oil against Lactococcus garvieae in laboratory conditionson rainbow trout
European Journal of Experimental Biology, 2014Co-Authors: Ahmad Rafiee Pour, Seyed Saeed Mirzargar, Mehdi Soltani, Hossein Ali Ebrahimzadeh Mousavi, Seyed Ali MostafaviAbstract:The aim of this study were to investigate the antibacterial effects of Cuminum Cyminum L. and Rosmarinus officinalis essential oil and extracts against Lactococcus garvieae in laboratory conditions on rainbow trout. The study also aimed to identify the minimum inhibitory concentration (MIC) of Cuminum Cyminum L. and Rosmarinus officinalis essential oil against this strain (Lactococcus garvieae). In this experiment, 11 strains of Lactococcus garvieae were collected from different provinces of Iran. In addition, we has been evaluated the antibacterial effects of Cuminum Cyminum L. and Rosmarinus officinalis extracts and essential oils. After the laboratory cultured Lactococcus garvieae strains, the different dilutions of Cuminum Cyminum L. and Rosmarinus officinalis essential oils were added to the culture medium at three different temperatures (20, 30 and 37 °C). Differences between extracts and essential oil of C. Cyminum L. and Rosmarinus officinalis were tested with analysis of variance. Results of this experiment showed that the extracts of Cuminum Cyminum L. and Rosmarinus officinalis against Lactococcus garvieae has not effects. The minimum inhibitory concentration of C. Cyminum L. essential oil in the culture medium of strains L. garvieae at three different temperatures were effective. From the results of the present study it can be concluded that Cuminum Cyminum L. and Rosmarinus officinalis essential oils could be effective for the inhibition of Lactococcus garvieae in rainbow trout.

Investigation of Antibacterial Effect of Cuminum Cyminum and Carum carvi against Streptococcus mutans and Streptococcus pyogenes
Novelty in Biomedicine, 2019Co-Authors: Mona Ghazi, Hossein Goudarzi, Hamidreza Ataee Zadeh Ardekani, Maliheh Habibi, Eznolla Azargashb, Bahareh Hajikhani, Mehdi GoudarziAbstract:Background: Streptococcus mutans is major cause of tooth decay. In addition, there is some report about effects of Streptococcus pyogenes on odontogenic infections. Herbal drugs is now administrating for treatment of some disease. The aim of this study was to evaluate the antibacterial effect of Cuminum Cyminum and Carum carvi against Streptococcus mutans and Streptococcus pyogenes. M aterials and Methods: In this study, standard strains of Streptococcus mutans and Streptococcus pyogenes were used, and ethanolic extract was prepared in the microbiological laboratory of Shahid Beheshti University of Medical Sciences. The experiment was repeated 6 times and chlorohexine 2% was used as a control. R es ults: The best effect of Carum carvi was on Streptococcus mutans , whereas on Streptococcus pyogenes both extracts of Cuminum Cyminum and Carum carvi showed the same effect. C onclusion: This study showed, due to the fact that the Cuminum Cyminum and Carum carvi extracts exhibited excellent antibacterial properties, they could be a suitable candidate in compounds such as mouthwash, toothpastes and Gums. Therefore, could be used in the prevention and treatment of future oral and dental diseases.

an artificial intelligence approach for modeling volume and fresh weight of callus a case study of cumin Cuminum Cyminum l
Journal of Theoretical Biology, 2016Co-Authors: Ali Mansouri, Ali Fadavi, Seyed Mohammad Mahdi MortazavianAbstract:Cumin (Cuminum Cyminum Linn.) is valued for its aroma and its medicinal and therapeutic properties. A supervised feedforward artificial neural network (ANN) trained with back propagation algorithms, was applied to predict fresh weight and volume of Cuminum Cyminum L. calli. Pearson correlation coefficient was used to evaluate input/output dependency of the eleven input parameters. Area, feret diameter, minor axis length, perimeter and weighted density parameters were chosen as input variables. Different training algorithms, transfer functions, number of hidden nodes and training iteration were studied to find out the optimum ANN structure. The network with conjugate gradient fletcher-reeves (CGF) algorithm, tangent sigmoid transfer function, 17 hidden nodes and 2000 training epochs was selected as the final ANN model. The final model was able to predict the fresh weight and volume of calli more precisely relative to multiple linear models. The results were confirmed by R(2)≥0.89, R(i)≥0.94 and T value ≥0.86. The results for both volume and fresh weight values showed that almost 90% of data had an acceptable absolute error of ±5%.
