Opis:
The aim of this study was to determine the effect of water extracts prepared from fresh and dry matter of wild thyme (Thymus serpyllum L.) on feeding adults and larvae of Colorado potato beetle (Leptinotarsa decemlineata Say.). The experiment was conducted in the laboratory, in six replicates. Dry extracts were prepared at concentration of 2%, 5% and 10%, while the fresh plant at concentration of 10%, 20% and 30%. Feeding intensity assessment was conducted by dipping leaves of potato in respective solutions of the extracts and determining the mass of food consumed by adults and larvae, and changes of larvae body weight once daily. In addition, absolute deterrence index and palatability index were calculated. The results of the experiment showed that for an efficient limitation of the feeding adult Colorado potato beetles, an extract from dry matter of wild thyme with a concentration of at least 10% should be used. L4 larvae appear to be considerably more susceptible to the effect of T. serpyllum extract. In their case, an efficient limitation of the feeding, as well as body weight gain can be obtained using extracts from both dry and fresh matter, at concentrations of over 5% for dry matter and over 20% for fresh matter. With the increase of extract concentration, the value of the calculated palatability index decreases, and the deterrence index value increases.

Opis:
Garden thyme is a very important essential herbal plant grown in Poland. As well as being able to regulate digestion processes, thyme herbage possesses disinfecting, expectorant, antioxidant, spasmolytic properties. Research has been launched to define the effect of NPK fertilisation on yielding, the content of essential oil as well as the mineral composition of garden thyme (Thymus vulgaris L.) herbage. The experimental factor consisted of NPK mineral fertilisation applied into soil at the following doses per hectare and proportions: A0 – without mineral fertilisation, A1 – 30 kg N + 22 kg P + 100 kg K (N:P:K was: 1:0.75:3.33), A2 – 60 kg N (30 kg N + 30 kg N) + 22 kg P + 100 kg K (1:0.37:1.67), A3 – 90 kg N (45 kg N + 45 kg N) + 22 kg P + 100 kg K (1:0.24:1.11). The experiment comprised 4 fertilisation objects with 4 replications, and the sowing area and the harvest area of 3 m2 plot-1. Nitrogen was applied in the form of ammonium nitrate twice: pre-sowing as well as after plant emergence. Phosphorus and potassium were used pre-sowing, in the form of triple superphosphate 40% and 60% of potassium salt, respectively. The doses of 152 kg NPK ha-1 (1:0.75:3.33) – A1 and 182 kg NPK ha-1 (1:0.37:1.67) - A2 showed the most favourable effect on the yield of fresh weight, air-dried weight and essential oil of herbage as well as the quality characteristics of the yields. The dose of 152 kg NPK ha-1 (A1), including 30 kg less nitrogen, was as favourable as that of 182 kg NPK ha-1 in terms of the content of air-dry weight of herbage, essential oil as well as mineral nutrients. Its application also resulted in a similar yield of essential oil. The application of 212 kg NPK ha-1 (1:0.24:1.11) was economically unjustified since, in general, it decreased the size of the yield of fresh weight of herbage and the values of its parameters studied.

Opis:
The influence of the time of distillation on the content and composition of essential oil isolated from wild thyme (Thymus serpyllum L.) by hydrodistillation was investigated. The GC-MS data showed that the essential oil was rich in carvacrol (30.90–46.16%) and its biogenetic precursors γ-terpinene (5.72–9.09%) and p-cymene (4.51–13.46%). Other constituents identified in significant amounts were β-caryophyllene, carvacrol methyl ether and (-)-β-bisabolene. On the basis of the obtained data it was proved that time of distillation had no effect on essential oil content. Moreover, there was no significant effect of the distillation time on the content of essential oil constituents found in the experiment.
Zbadano wpływ czasu destylacji na zawartość i skład olejku eterycznego wyizolowanego z macierzanki piaskowej (Thymus serpyllum L.) na drodze hydrodestylacji. Analiza GCMS wykazała, że olejek eteryczny zawierał dużo karwakrolu (30,90–46,16%), γ-terpinenu (5,72–9,09%) i p-cymenu (4,51–13,46%). Pozostałe składniki zidentyfikowane w znacznych ilościach w olejku to β-kariofilen, eter metylowy karwakrolu i (-)-β-bisabolen. Na podstawie uzyskanych wyników wykazano, że czas destylacji nie miał wpływu na zawartość olejku eterycznego, co więcej nie miał też istotnego wpływu na zawartość głównych składników olejku.

The aim of the study was to investigate the influence of plant growth regulators on callus culture of common thyme (Thymus vulgaris L.) and the possibility of using such callus cultures to obtain rosmarinic acid. The explants used to initiate shoot culture were the seeds of common thyme. The seeds were individually placed into test tubes with MS culture media of macro- and micro-element content according to Murashige and Skoog (1962). For the purpose of initiation of cultures, leaves dissected along the vascular bundle were used. The leaves were placed on MS medium with the addition of BAP in combination with NAA in a concentration of 3 and 5 mg•dm-3. Propagation of callus cultures was conducted with the use of fragments of callus tissue placed on MS media supplemented with BAP used separately in a concentration of 3 mg•dm-3, and in combination with NAA (1, 2, 3 mg•dm-3) and 2,4-D in a concentration of 0.5, 1 or 1.5 mg•dm-3 respectively. In each stage of the experiment, explants placed on MS media without the addition of plant growth regulators were the control. It was found that initiation of common thyme cultures should be conducted on MS media without plant growth regulators. For the purpose of initiation of callus culture of common thyme, the optimal culture medium was MS with the addition of 3 mg•dm-3 BAP and NAA. Propagation of callus tissue of common thyme should be conducted on culture media supplemented with 3 mg•dm-3 BAP used in combination with 1 mg•dm-3 NAA. It was observed that the mass of the propagated callus tissue decreased with an increase of NAA content.

Opis:
The aim of this study is to determine the effects of biochar that obtained from walnut shell and thyme stalk on yield and biomass development of pepper plant. Biochar obtained by self-constructed oxygen-free reactor at 400°C. According to experimental design, 2 different biochar raw materials (walnut shell and thyme stalk) at 3 different doses (0, 0.1 and 0.2% w/w) were evaluated in either with or without sulphur application (0 and 0.1% w/w). Results revealed that the all parameters tested were greatly influenced from raw material, biochar dose as well as sulphur applications. Significant differences were determined between the raw materials in which the biochar was made. According to mean values the walnut shell biochar provide 38% more shoot dry weight than thyme stalk biochar. These findings clearly indicate that although biochar almost consisted of carbon, all of the biochar are not the same, and depends on the raw material; biochar even can reduce plant growth. The effect of sulfur application was also significant, especially in the pots where biochar and sulfur were applied together. The lowest yield value was determined at control as well as 0.1% thyme stalk biochar applied pots as 34.2 and 33.4 g pot-1, respectively while the highest yield value was determined at 5 g walnut shell biochar and sulphur applied pot as 75.7 g pot-1. It has been determined that dose and efficiency studies should be performed for each raw material to determine optimal biochar source and doses.

Cookies are a group of convenient food products that are popular among consumers. They may contain high amounts of fats, which can be prone to oxidation. To retard the oxidative deterioration, synthetic and natural antioxidants may be added. Herb and spice extracts can be sources of natural biologically active substances with antioxidant activity. In this work, electron paramagnetic resonance spectroscopy was used to monitor the lipid oxidation in cookies with rosemary and thyme extracts subjected to the storage in elevated temperature. It was shown that thyme extract can be used as a natural antioxidant source for the preparation of bakery products, while the rosemary extract should be used with care in fat-rich products exposed to high temperatures.

Opis:
Thyme belongs to herbal plants, the yield and quality of which depend on biological factors, agrotechnical procedures and the way of processing and storage. Basic factor differentiating the biological value of plants is fertilization, including manure, as well as plant growth and development, which is significantly influenced by the pH of the substrate, in which the plants are grown. The aim of the study was to determine the effect of manure dose (12.5 and 25 g·dm–3) and calcium carbonate (5 and 15 g·dm–3) on the yield and biological value of thyme. The fresh thyme mass yield was changed under the influence of the factors used. The highest yield of raw material was recorded after using a high dose of manure and calcium carbonate. Significantly higher concentration of essential oil in thyme was found after feeding the plants with higher dose of manure. The inverse relationship was demonstrated for the amount of L-ascorbic acid that decreased with the increase in manure dose. Calcium fertilizers not only serve to regulate the acidity, but are also a source of calcium for plants. After applying a higher dose of CaCO3, significant increase in the yield of fresh thyme mass was observed and higher dry matter content was recorded

Leather products provide an ideal environment for microbial growth. In order to prevent the appearance and spread of various types of microorganisms, it is treated with selected biocides and even essential oils. The aim of this paper was to investigate the antifungal activity of selected essential oils applied to finished chromium tanned leather which is intended for leather fancy products. Antifungal activity was evaluated according to the PN-EN 14119: 2005 standard. Four finished chromium tanned leathers were tested, each of which was soaked in the following essential oils: tea tree essential oil at a concentration of 1, 2 and 5% and thyme essential oil at concentration of 1, 2 and 5%. The results obtained indicated that leather finishing with thyme essential oil showed the antimicrobial activity against Aspergillus niger, Chaetomium globosum and Candida albicans strains. The application of 5% thyme essential oil to leather samples inhibited the growth of all strains tested. Using tea tree essential oil on leather samples showed a antimicrobial effect only against Candida albicans. The application of essential oils in the leather finishing process may be an alternative to biocides used in the tanning industry.

Opis:
Members of Candida species cause significant problems in medicine and in many industrial branches also. In order to prevent from Candida sp. development, essential oils are more and more frequently applied as natural, non-toxic, non-pollutive and biodegradable agents with a broad spectrum of antimicrobial activity. The aim of the research was to determine changes in morphology and metabolic properties of Candida albicans in the presence of thyme and tea tree oils. Changes of enzymatic activity of isolates were observed in the presence of both tested essential oils, and they were primarily associated with loss or decrease of activity of all enzymes detected for control. Furthermore, only for 3 out of 11 isolates additional activity of N-acetyl-β-glucosaminidase, α-mannosidase, α-fucosidase and trypsin was detected. Vivid changes in biochemical profiles were found after treatment with tea tree oil and they were related to loss of ability to assimilate d-xylose, d-sorbitol and d-trehalose. The main differences in morphology of isolates compared to the control strain concerned formation of pseudohyphae structures. Both examined essential oils caused changes in cell and colony morphology, as well as in the metabolism of Candida albicans. However, the extent of differences depends on the type and concentration of an essential oil. The most important finding is the broad spectrum of changes in yeast enzymatic profiles induced by thyme and tea tree oils. It can be supposed that these changes, together with loss of ability to assimilate saccharides could significantly impact Candida albicans pathogenicity.

Opis:
The aim of this experiment was to determine the effects of three foliar biopreparations applied once or twice (growth stimulant Bio-algeen, fertilizer Herbagreen Basic, and Effective Microorganisms in the form of EM Farming spray) on yield and quality of herbal raw material of organically grown garden thyme (Thymus vulgaris). It was proved that the Bio-algeen had an effect on increasing thyme productivity, whereas Effective Microorganisms had no impact at all on herb yield. The beneficial action of biopreparations was more evident under favorable hydrothermal conditions over the study period than under unfavorable conditions. The biopreparations stimulated an increase in the essential oil content in the thyme herb. Bio-algeen, especially when applied twice, had the greatest positive influence on the quality of raw material, Effective Microorganisms were found to have a smaller effect (positive and negative), whereas Herbagreen Basic had positive effect on thyme yield and essential oil content. The effect of Bio-algeen, and to a lesser extent that of Effective Microorganisms, on the content of natural antioxidants (phenolic acids, polyphenols) in the thyme raw material and, moreover, its impact on free radical scavenging and antioxidant activity should be considered to be a particularly valuable finding. Due to application of the Bio-algeen, herbal raw material characterized by the best health-promoting parameters can be obtained.

Opis:
A field experiment in growing garden thyme was carried out in Jaroszewice (the central Lublin region) in 2008–2010. Three growth biostimulators (Asahi SL, Bio-algeen S 90, and Tytanit) were used in the study. Plots with no foliar application of these growth stimulators established the control group. Carrot, faba bean, and spring wheat forecrops were the other experimental factors. The present study showed that the best quantitative parameters of thyme raw material were observed after the application of the growth simulators. The root forecrop (carrot) also had a beneficial effect on thyme yield. Thyme crop protection without the application of the growth simulators resulted in the deterioration of the biometric traits and yields of this crop. The treatment with no application of the growth simulators was the most beneficial for the chemical composition of thyme raw material.
Eksperyment polowy z uprawą tymianku właściwego prowadzono w latach 2008-2010 w Jaroszewicach (środkowa Lubelszczyzna). W badaniach zastosowano trzy biostymulatory wzrostu (Asahi SL, Bio-algeen S 90 i Tytanit). Obiektem kontrolnym były poletka bez dolistnego stosowania stymulatorów wzrostu. Drugi czynnik badany w doświadczeniu stanowiły przedplony: marchew, bobik i pszenica jara. Badania dowiodły, że najkorzystniejsze parametry ilościowe surowca tymianku obserwowano po aplikacji stymulatorów wzrostu. Korzystne oddziaływanie na plonowanie tymianku posiadał także przedplon z rośliny okopowej (marchew). Metoda pielęgnacji zasiewów tymianku bez aplikacji stymulatorów wzrostu, wpływała na pogorszenie cech biometrycznych i plonu rośliny. Brak aplikacji stymulatorów wzrostu był korzystniejszy dla składu chemicznego surowca tymianku.

Opis:
One of the oldest medicinal plants in the world is thyme (Thymus vulgaris L.). On the biological value of this plant is affected by biotic and abiotic conditions, which include fertilizers and soil type. The aim of the present study was to determine the effect of organic fertilization and the type of substrate on the biological value of the thyme herb. Plants were grown in a greenhouse in a different type substrates: peat and peat + sand, using varying amounts of manure 10, 20, 30 g·dm-3 of substrate. In the obtaining raw material was determined the content of essential oil, dry matter, L-ascorbic acid, total nitrogen and proteins. There was a significant increase in the N-total and protein contents in thyme herb after application of increasing doses of examined manure independently of the test substrate. Applied natural fertilization and type of substrate did not affect significantly the content of essential oil in Thymus vulgaris L. herb. The highest content of L-ascorbic acid and dry matter was obtained for thyme after application of the lowest dose of manure, regardless of the substrate used.
Thymus vulgaris L. jest jedną z najstarszych roślin przyprawowych świata. Na wartość biologiczną tej rośliny mają wpływ zarówno warunki biotyczne, jak i abiotyczne, do których zalicza się nawożenie oraz rodzaj podłoża. Przeprowadzone badania miały na celu określenie wpływu zróżnicowanego nawożenia obornikiem (dawki 10, 20, 30 g dm-3 podłoża) i różnego rodzaju podłoża (torf, torf + piasek) na zawartość suchej masy, białka, azotu ogółem, kwasu L-askorbinowego oraz olejku eterycznego w surowcu. Stwierdzono istotny wzrost zawartości N ogółem i białka w zielu tymianku po zastosowaniu wzrastających dawek obornika niezależnie od badanego podłoża. Zróżnicowane nawożenie naturalne oraz rodzaj podłoża nie wpłynęły istotnie na zawartość olejku w zielu Thymus vulgaris L. Największą zawartość kwasu L-askorbinowego oraz suchej masy otrzymano w tymianku po zastosowaniu najniższej dawki obornika niezależnie od użytego podłoża.

Opis:
In 2005-2007, in a field experiment, the yield and quality of the thyme herb of the Polish cultivar Słoneczko in organic farming were tested. The experiment was established on six different organic farms and one conventional farm in Poland. The following features were evaluated: fresh and dried herb yield, stem fraction in herb, essential oil content, and microbiological purity. Only from one organic farm in Słońsk thyme herb yield was higher compared with the yield from conventional cultivation, although it contained a high amount of stems. Organic thyme herb was characterized by a high content of essential oil. Evaluation of microbiological purity showed that herb contamination from both types of cultivation did not exceed the standard for raw materials treated with hot water.
W latach 2005-2007 w doświadczeniu polowym zlokalizowanym w Polsce w sześciu gospodarstwach ekologicznych i jednym konwencjonalnym badano plonowanie, jakość surowca tymianku oraz przydatność polskiej odmiany Słoneczko do upraw ekologicznych. Oceniano następujące cechy: plon świeżego i powietrznie suchego ziela, udział łodyg w surowcu, zawartość olejku eterycznego oraz czystość mikrobiologiczną. Plon surowca tymianku pochodzącego z uprawy ekologicznej tylko z jednej lokalizacji (Słońsk) był większy niż z uprawy konwencjonalnej. Surowiec ten jednak charakteryzował się dużym udziałem łodyg. Surowiec tymianku pochodzący z upraw ekologicznych charakteryzował się wysoką zawartością olejku eterycznego, jednak była ona mniejsza niż ziela z upraw konwencjonalnych. Ziele pochodzące z uprawy konwencjonalnej zawierało najwięcej azotanów. Ocena czystości mikrobiologicznej surowca tymianku wykazała, że stopień zanieczyszczenia surowców zarówno z uprawy ekologicznej, jak i konwencjonalnej nie przekraczał dopuszczalnych norm dla surowców poddawanych działaniu gorącej wody.

Opis:
Introduction: Spice plants are a rich source of biologically active compounds. Processes of drying, limits the development of microorganisms and biochemical reactions in raw herbs, at the same time modifies their chemical composition. Objective: The aim of this work was to evaluate the effect of drying process of selected plants on their antioxidant potential and the content of biologically active compounds. Methods: The herbal materials thyme herb (Thymus vulgaris L.), sage leaves (Salvia officinalis L.) and rosemary leaves (Rosmarinus officinalis) were dried using two methods: convective (at 30° C), and freeze-drying. In both, fresh and subjected to drying processes herbs, changes in total polyphenol and antioxidant potential (with the DPPH radical), vitamin C (in the form of ascorbic acid) and chlorophyll pigments contents, were studied. Results: The highest content of polyphenols and vitamin C was recorded in rosemary, while sage was characterized by the highest content of chlorophylls. It was found that the drying processes caused large losses of vitamin C (ascorbic acid) and dyes in comparison to the fresh material. The highest losses of vitamin C occurred in convection dried sage (95%), while most was preserved in lyophilised thyme (losses 74%). Drying had also influenced the reduction of the content of chlorophylls with the largest loss of these compounds, at 94% observed in the freeze-dried rosemary. However, the content of polyphenols increased, underscoring a large impact on the antioxidant activity of herbs. Conclusions: Drying processes resulted in the release of phenolic compounds, so their content increased three to four times in the case of rosemary and sage. The largest increase was observed in the case of lyophilised thyme. Simultaneously, the antioxidant potential was significantly increased. Herbal droughts proved to be a rich source of antioxidant compounds with promising applications as a food additive.
