“…Therefore, in recent years, there has been increasing interest in searching for biological antifungal agents to replace synthetic pesticides. Among natural antimicrobial products, particularly interesting are plant products such as essential oils (EOs), which are some of the most promising phytochemicals and can be used for the preservation of cereals and their products (Singh et al 2010; Boukaew et al 2017; Foltinová et al 2017; Gakuubi et al 2017). …”

Essential oils (EOs) are products of plant origin and include mixtures of different chemical compounds. These volatile substances have many interesting properties, including antifungal properties. Fungi may develop under field conditions on crops such as wheat or corn and are able to synthesize mycotoxins, which adversely affect livestock and human health. In the present study, selected EOs were used to inhibit the growth of Fusarium graminearum and F. culmorum and reduce the concentrations of mycotoxins in wheat grain. The EOs significantly inhibited the growth of tested Fusarium species (90.99–99.99%), as determined based on ergosterol quantitative analysis. Only the addition of orange oil to F. culmorum exhibits a different inhibition capacity (68.13%). EO application resulted in a large reduction in zearalenone content (99.08–99.99%); only in the case of orange oil application was the reduction estimated at approximately 68.33%. However, all EOs provided a significant reduction in the concentration levels of group B trichothecenes (94.51–100%). It can be concluded that EOs inhibit the growth of fungi of the genus Fusarium and reduce concentration levels of the mycotoxins zearalenone and group B trichothecenes.

“…Essential oil of E. camaldulensis was shown to inhibit mycelial growth of fungi, F. oxysporum, F. verticillioides, F. solani, F. subglutinans and F. proliferatum. It was observed as effective at 7, 8 and 10 μL/mL on the 5 th day [32]. The results revealed that E. camaldulensis leaf oils provided 100% inhibition of the mycelial growth of Thanatephorus cucumeris (5 mg/mL), and Chaetomium globosum (10 mg/mL).…”

Abstract:In this study, chemical compositions of the volatile oil extracted from Eucalyptus camaldulensis Dehnh. were analyzed by using GC and GC-MS. The oxygenated sesquiterpenes, monoterpene hydrocarbons, sesquiterpene hydrocarbons and oxygenated monoterpenes compositions were detected in the sample studied. Pesticidal effects of this oil were investigated on storage insect pests like Rhizopertha dominica F. . The essential oil was tested on some fungal pathogens and weeds. As fungal pathogens, Verticillium dahliae Kleb, Fusarium oxyporum Schl., Phytium debaryanum Auct. non R. Hesse, Sclerotinia sclerotiorum (Lib.) de Barry and Rhizoctania solani Kühn. were used while tests on the weeds were performed on Convolvulus arvensis L., Melilotus officinalis L. and Amaranthus retroflexus L. in invitro conditions. E. camaldulensis essential oil was found to be effective at 10 and 20 µL against all the tested insect pests. Our results also showed that growth of fungal mycelial as well as weed stems and roots were significantly affected by essential oil. In 10 and 20 µL, V. dahliae, P. debaryanum, F. oxyporum and S. sclerotiorum mycelial growth were inhibited in 7 days, while no effect was observed on R. solani mycelial growth in this duration. On the other hand, the applications of the oil to the weeds showed different results for each species examined. Although at 5, 10 and 20 µL concentrations of E. camaldulensis essential oil did not affect the root and stem growth of C. arvensis, the stem and root growth of M. officinalis and A. retroflexus were reduced by the tested essential oil at the same concentration and time. The research results suggest that E. camaldulensis essential oil might have potential to be used as a natural pesticide as well as fungicide.

“…Furthermore, one of the more commonly used in antifungal bioassays is the poisoned food technique [26]. The huge number of different assays often makes it impossible to compare results between different studies.…”

The increase of many deadly diseases like infections by multidrug-resistant bacteria implies re-inventing the wheel on drug discovery. A better comprehension of the metabolisms and regulation of diseases, the increase in knowledge based on the study of disease-born microorganisms’ genomes, the development of more representative disease models and improvement of techniques, technologies, and computation applied to biology are advances that will foster drug discovery in upcoming years. In this paper, several aspects of current methodologies for drug discovery of antibacterial and antifungals, anti-tropical diseases, antibiofilm and antiquorum sensing, anticancer and neuroprotectors are considered. For drug discovery, two different complementary approaches can be applied: classical pharmacology, also known as phenotypic drug discovery, which is the historical basis of drug discovery, and reverse pharmacology, also designated target-based drug discovery. Screening methods based on phenotypic drug discovery have been used to discover new natural products mainly from terrestrial origin. Examples of the discovery of marine natural products are provided. A section on future trends provides a comprehensive overview on recent advances that will foster the pharmaceutical industry.
