“…In a previous study by Abdulaziz et al [ 18 ], the diameters were higher in thyme essential oil (42.4±6.5) in comparison with rosemary essential oil (11.8±2.8). The serial two-fold dilutions of the tested essential oils showed that both oils exhibited antifungal activities even at very low concentrations.…”

Background and Purpose :In traditional medicine, herbal products still remain the principal source of pharmaceutical agents. The present study aimed to investigate the antifungal effects of Echinophora platyloba and Rosmarinus officinalis extracts on C. albicans species.Materials and Methods :The aqueous and ethanolic leaf extracts of E. platyloba and R. officinalis, collected from the mountainous regions of Iran, were screened in terms of antimicrobial activity against C. albicans strains, using the agar well diffusion method. The minimum inhibitory concentration was determined by the microtitration technique.Results:Overall, the results showed that the leaf extracts of E. platyloba and R. officinalis had strong antimicrobial activities. Also, based on the findings, R. officinalis leaf extracts exhibited higher antimicrobial activity. The ethanolic leaf extracts of E. platyloba and R. officinalis showed good antimicrobial activity against C. albicans strains. However, the aqueous extracts did not show any major activities against the tested C. albicans strains. On the other hand, the ethanolic extracts exhibited major antimicrobial properties against C. albicans strains. The highest minimum inhibitory concentration was reported in E. platyloba leaf extracts. Conclusion:The present results indicated some advantages of E. platyloba and R. officinalis leaf extracts, which could be applied for the treatment of microbial infections.

Growth of fruits which form an important part of human diet has been jeopardized by the many fungal diseases that are present today. This study was conceived to isolate the most common fungal pathogens in passion fruits. Fungi were isolated using potato dextrose agar in addition to characterization using morphological, cultural, and biochemical means. Extraction of essential oils from rosemary (Rosmarinus officinalis) and eucalyptus (Eucalyptus agglomerata) was done. Before carrying the sensitivity test of essential oils to the fungal isolates, constituents of the essential oils were determined. The most common fungal pathogens isolated from passion fruits were Alternaria spp. (45%), Fusarium spp. (22%), Colletotrichum spp. (17%), and Penicillium spp. (16%). There was a relationship between heating time and yield of essential oils in rosemary (r = 0.99) and eucalyptus (r = 0.99). Conversely, there was no significant difference in the amount of essential oils produced by rosemary and eucalyptus (P = 0.08). Furthermore, there was a significant difference in growth inhibition of the fungal pathogens between essential oils from rosemary and eucalyptus (P = 0.000438). Fungal pathogens isolated from passion fruits can be controlled using essential oils from rosemary and eucalyptus. The oils need to be produced in large scale.

Biological activities of essential oils from various plants, including Rosemary, have been attributed to the presence of specific chemical compounds with antimicrobial, anti-inflammatory and antioxidant activities. The aim of this study is to estimate the antioxidant and antifungal activity of Rosmarinus officinalis essential oil extract. The study included the extraction of essential oil using a Clevenger apparatus. The chemical compositions were evaluated by GC-MS and High Performance Liquid Chromatography (HPLC).The rosemary essential oil extract was tested with regard to antioxidant utilizing 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay. Microtiter plate Assay used to determine the antifungal and antibiofilm activity. The result showed that the GC-MS analysis revealed that the major components determined in R. officinalis essential oil were linalool (17.09 %), L-Borneol (11.92 %), Verbenone (8.52 %), camphor (5.30 %), Eucalyptol (4.79 %), while the chemical compositions identified by HPLC shows four phenolic acids were identified in the essential oil, Rosmarinic acid, Caffeic acid, p-Coumaric acid, 4-hydroxybenzoic acid, and lignans (medioresinol), while Isorhamnetin was the only flavonol detected. The free radicals scavenging activity increased gradually with the increase in the concentration of essential oil which was 81.59 % when compared with BHT and V.C (92.34 and 97.42) respectively. The results of the antifungal activity revealed that Minimum Inhibitory Concentration of C. albicans and C. krusei was 3.125%, while the MIC of C. glabrata was 12.5% in contrast with the highest MIC which recorded for C. tropicalis at 25% of rosemary essential oil. The current results revealed that the reduction of bofilm formation among C. albicans and C. krusei was obvious at the lower concentration (1.56%), where the percentage of biofilm formation in C. albicans was (91.25%) and C. krusei was (84.25%), while C. tropicalis exhibit (86.32%) for biofilm reduction at the concentration (12.5%) of rosemary essential oil, also it was found that the effect of essential oil on C. glabrata biofilm formation was at the concentrations 3.125% and 6.25%. The findings of this study indicated to the significant effect of rosemary essential oil against the growth and biofilm formation of the important pathogenic yeast C. albicans at low concentrations.
