The applying of antibiotics in animal husbandry leads to the spread of antimicrobial resistant pathogens among domestic animals, which are subsequently transmitted to humans through the food chain. The analysis of literature data on the results of the study of phytochemicals of plant origin in the form of essential oils of medicinal and aromatic plants as one of the possible alternatives to feed antibiotics is presented. Such additives should reduce the incidence of animals by inhibiting pathogenic microflora, provide the animal with a larger amount of energy and nutrients by reducing the bacterial load in the intestine, reduce internal inflammatory processes by improving the immune system, and should be economically beneficial. A review of scientific studies showed that essential oils do have bactericidal properties, but their effect on the productive performance of animals still requires further research. Differences in animal productivity when using essential oils may be due to researchers using different doses, different test conditions (especially climatic conditions), and possible synergistic and antagonistic properties of essential oils with other feed substances.

Allelopathic Interaction

Medicinal and aromatic plants have the ability to transmit volatile allelochemicals and affect their surrounding organisms. In this regard, their interaction should also be considered. The inhibitory effects of 112 essential oils on lettuce seed and seedling were investigated by cotton swab method. Germination (G%), Mean germination time (MGT), Lethal of embryo (L%), dormancy (D%), radicle growth (R%), and hypocotyl growth (H%) were measured. Two methods were used for evaluating allelopathic interaction effects: the simplified modified dilution check-board technique (SMCT) and the isobologram. Thymus daenensis had the highest inhibitory effect on G% (IC50 = 2.9 ppm) and the most lethal effect on the embryo (LC50 = 7.2 ppm). Thymus transcaspicus, Dracocephalum moldavica, Artemisia sieberi and Amomum subulatum had the greatest effect on MGT. Ziziphora tenuior, Trachyspermum ammi and Pelargonium graveolens had the highest effect on D%. Origanum vulgare was the strongest growth inhibitor. The highest synergistic effect on G% was in A. subulatum + Mentha suaveolens, on H% was related to Perovskia abrotanoides + T. daenensis, and on R% was observed in Artemisia vulgaris + M. suaveolens. The results of this study can lead to identification of new phytotoxic compounds in EOs and control weeds more effectively.

Antioxidant Power

In the present study, the yield, the chemical composition, and the antioxidant activities of the essential oils (EOs) of eight medicinal and aromatic plants (MAPs) cultivated under two environmental conditions characterized by a different altitude (namely mountainous and plain) were evaluated. Cultivation at different environmental conditions resulted in significant differences in the chemical composition and antioxidant activity for most of the studied species. In particular, high altitudes resulted in increased phenolic compounds’ content and antioxidant activity for artemisia plants, while specific parameters increased in the case of spearmint (total phenols) and rosemary (flavonoids). In contrast, in pelargonium, all the tested parameters were positively affected in the plain area, whereas, for laurel and sage, only flavanols remained unaffected. EO yield in mountainous pelargonium and spearmint decreased while, in mountainous laurel, pelargonium and spearmint increased when compared to plain areas. In addition, the major EO constituents’ content for most of the species were affected by environmental conditions. The 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and ferric reducing antioxidant power (FRAP) were variably correlated with total phenols, flavonoids, and flavanols, depending on the species and the altitude. Lastly, in limited cases, antioxidant activity (DPPH or FRAP values) was positively correlated with some EO components (e.g., borneol and β-pinene in artemisia and laurel plants grown in the plain, respectively, or 1,8-cineole in mountainous grown verbena plants). In conclusion, environmental conditions (altitude) affected antioxidants’ content and EO yield and composition of the studied MAPs. These findings can be used to introduce cultivation of MAPs in specific ecosystems for the production of high added value products.

Effect of Botanicals on Infestation Intensity of Aceria Guererronis Keifer in CoconutThe withdrawal of chemical pesticides opens up a new perspective to control pests through botanical extracts. The essential oils derived from various medicinal and aromatic plants proved to have antifungal, antibacterial and insecticidal properties. The present study is directed towards management of a dreaded pest of coconut i.e. eriophyid mite through exploitation of those properties of the plants. The efficacy of a botanical biocide formulated by using seven different aromatic and medicinal herbs against the infestation intensity of eriophyid mite was tested in the experiment at five different coconut farms in different coconut growing states of India. Four application of the formulated product resulted up to 72.17% damage reduction.
