“…group of secondary metabolites and play a key role in plant defense against fungal and bacterial pathogens [Jamiołkowska and Kopacki 2019]. Polyphenolic compounds are widely present in many plant species, including yarrow flowers [Devrnja et al 2017, Ivănescu et al 2018, Mot et al 2018, Kaczorová et al 2021.…”

“…Not only flavonoids, but also essential oils and their composition determine the antimicrobial effect of tansy plant [Vilhelmova et al 2020]. Chlorogenic [Ivănescu et al 2018] and cichoric acids [Bączek et al 2017] are the main phenolic compounds found in tansy extracts, and the variation in the composition of bioactive compounds in the extracts and essential oils depends on the geographical [Mot et al 2018].…”

Crops are subject to yield losses caused by the presence of pests whose species and population diversity are changing with climate warming. The use of agrochemicals is still the most effective method of plant protection against diseases and pests. However, the intensive use of pesticides in some EU countries makes it necessary to search for alternative methods that can be applied in plant protection for consumer and environmental safety. The aim of the study was the laboratory evaluation of the fungistatic effect of extracts of herbal plants occurring in natural state in Poland: horseradish (Armoracia rusticana L.), yarrow (Achillea millefolium L.) and tansy (Tanacetum vulgare L.) on selected polyphagic phytopathogenic fungi (Alternaria alternata, Botrytis cinerea, Colletotrichum coccodes and Fusarium oxysporum). In this study, 5%, 10% and 20% concentrations of herbal water-extract extracts were applied to evaluate their effects on linear growth of fungi and inhibition of their growth relative to control. Total content of polyphenols and flavonoids was assessed in the extracts using spectrophotometry, and their antioxidant activity by applying the synthetic DPPH radical. The plant extracts of tansy and yarrow leaves were characterized by a higher content of polyphenols and flavonoids compared to horseradish leaf extracts; they also had a higher antioxidant activity. Plant extracts inhibited the growth of fungi to a different extent, depending on the species of fungus, type of extract, its concentration and duration of action. The strongest fungistatic effect was recorded for tansy and yarrow extracts, while the weakest for the extract of horseradish leaves. Plant extracts showed the weakest effect against Botrytis cinerea, inhibiting the development of this fungus only during the first days of the experiment. The present research is a preliminary study that will be used in the further to develop a biological preparation for the protection of agricultural and horticultural plants against fungal pathogens.

“…The phenolic fraction is more abundant in tansy extracts respect to thyme ones because flowers were present in tansy sample used, while thyme sample contained only leaves. A very recent study on antioxidant activity of tansy shows that flowers extract has a higher total phenolic content with a consequently higher antioxidant activity (Anca Mot et al, 2018).…”

Bio-sourced substances used for crop protection in natural and organic farming have a positive impact both on human and environment health: plant extracts are effective to stimulate plant defense against pests and diseases, with no toxic effect and they could be classified as basic substances. The chemical characterization of thyme and tansy extracts were carried out with ICP and NMR techniques for the analysis of elemental content and organic components. Antioxidant activity was evaluated by DPPH method. Phytostimulant effects of extracts were evaluated on zucchini crop in a preliminary field test. Vegetative plant conditions were assessed by measuring the chlorophyll content. The 1% extracts were chosen for field trial because of their maximum antioxidant activity (over 80%) and their cheapness compared to 2% concentration. NMR showed that the spectrum of tansy highlighted the phenolic fraction in 6-9 ppm region and, in particular, at 5.9 ppm the signals of thymol, a peculiar antioxidant compound; while the spectrum of thyme is less significant. The field trial results showed a higher fruit yield and a positive effect on plant growth in treated plants respect to control ones, due to the composition and antioxidant activity of both plant extracts. In fact, thyme extract treated plants showed a yield equal to 6,4 kg per plant, higher than no treated ones, 5,1 kg per plant; also tansy extract induced a higher yield respect to control plant, respectively 5,6 and 3,9 kg per plant. The results obtained indicate the role of the extracts investigated as basic substances.

“…From the results showed above is deducted that by the two types of electrochemical methods using screenprinted carbon electrodes (DPV and CV) and Jenco microelectrodes (for iodide detection), iodide can be easily determined qualitatively and quantitatively. Both methods are safe and easy to use, and can be thought of as a portable system with a wide range of applicability [34][35][36][37][38][39][40] (screen electrodes are already used to detect toxic and bioactive compounds in the life sciences), alongside other validated methods for the same purpose [41][42][43][44][45][46][47]. Redox microelectrodes correlate in a good manner the redox status of the solution with KI concentration.…”

Iodine is a micronutrient of high importance for the health and good development of individuals. It is contained in many foods, but it is also part of the chemical component of oceans and soil. Its deficiency is still a problem of humanity, which has a serious repercussion on our health. It is therefore important to have specific, fast and cost effective methods of iodine detection from different samples. This work aims to identify optimal parameters for potassium iodide (KI) detection from different media, to be further applied to real samples: plant extracts, water, biological fluids. Results showed a significant difference in electrochemical results, depending on the pH values of the mixture and also on the time which influences the compounds stability. Differential pulse voltammetry and cyclic voltammetry using carbon printed sensors, as well as microsensors for redox status or direct iodide detection are important analytical tools which have a wide range of applications in the food, medicine, toxicology and other domains.
