IDENTIFICATION AND CONTENT OF PHENOLIC COMPOUNDS IN A BUTANOL FRACTION OF EXTRACT FROM THE FLOWERS OF TANACETUM VULGARE

Tanacetum vulgare L. (syn.: Chrysanthemum vulgare (L). Bernh) is a perennial medicinal plant with a Euro-Asian type of habitat. Tansy extracts have a wide biological and pharmacological activity. At the All-Russian Institute of Medicinal and Aromatic Plants, on the basis of the butanol fraction of the T. vulgare flowers extract was developed a drug with high choleretic and anti-inflammatory activity. In this regard, the aim of this work was to study the qualitative composition and quantitative content of phenolic compounds of the butanol fraction, which are supposed to determine its biological activity. For this was obtained a phenolic compounds fraction, isolated from the extract of inflorescences of T. vulgare plants grown on the VILAR experimental plot. High-performance liquid chromatography with diode-array detection in combination with high-resolution mass spectrometry (UPLC-PDA-HRMS) was used for the analysis. Our studies have shown that the butanol fraction of T. vulgare contains 7 phenolic compounds, among which myricetin-3-glucoside was detected for the first time. The content of phenolic compounds reaches 90%, while the main compounds are neochlorogenic, 3,5- and 4,5-dicofeylquinic acids, the proportion of which is 69%. Thus, the obtained data indicate that the pharmacological activity of the drug based on the butanol fraction of the extract from tansy flowers is due to the high content of caffeoylquinic acids.

Essential Oils and Supercritical CO2 Extracts of Arctic Angelica (Angelica archangelica L.), Marsh Labrador Tea (Rhododendron tomentosum) and Common Tansy (Tanacetum vulgare)—Chemical Compositions and Antimicrobial Activities

Traditionally, arctic Finnish Angelica (Angelica archangelica L.), marsh Labrador tea (Rhododendron tomentosum, syn. Ledum palustre) and common tansy (Tanacetum vulgare) have been used as medicinal herbs in folklore medicine. However, these underutilised plants are a source of, e.g., oil-based compounds, which could benefit many modern applications implemented by the green chemistry extraction methods, as well. We extracted Angelica, marsh Labrador tea and common tansy by non-toxic and recyclable extraction methods, i.e., hydrodistillation and supercritical carbon dioxide (scCO2) extraction; characterised the essential oils (EOs) and scCO2 extracts by combination of gas chromatography and mass spectrometry (GC-MS), and in addition, analysed the antimicrobial properties. As expected for Angelica root and common tansy inflorescence, the scCO2 extraction method produced less amount of volatile compounds compared to hydrodistillation. On the other hand, more coumarins, alkanes, fatty alcohols and fatty acids were obtained. Additionally, sesquiterpenoids palustrol and ledol were predominant compounds in both marsh Labrador tea EO and scCO2 extract. According to our results, however, all the EOs and scCO2 extracts showed broad spectrum of antimicrobial activities against the selected microbes, but the effects were extract-specific. The strongest and broadest antimicrobial activities were performed by marsh Labrador tea scCO2 extract, which showed extremely strong effect on Staphylococcusaureus subsp. aureus and strong effect on Candida albicans.

Antimicrobial effects of essential oils from Tanacetum vulgare L. and Salvia officinalis L., growing in Slovakia

Possible antimicrobial properties of essential oils isolated from Tanacetum vulgare L., and Salvia officinalis L., harvested from five different locations in Slovakia, were examined using the disc agar diffusion method and by the microdilution method. GC/MS analysis of the essential oil from Tanacetum vulgare L. resulted in the identification of 16 compounds constituting 82.1% of the total oil. Gram-positive bacteria, mainly Bacillus subtilis, were more susceptible to essential oils from both plants than were gramnegative species. Tested essential oils posses also anti-yeast activity. The shares of the constituents in the essential oils as well as their antimicrobial activity differed in dependence on the locality.

Research of beta-radioactivity of certain medicinal plants of Dnipro area

In the course of research conducted in the laboratory of radioecology of DNU, information was obtained on the beta-radioactivity of nine species of medicinal plants from two types of habitats – meadow biocenosis on the outskirts of the village. Kirovsky Dnipro region and a weed-meadow group near the town of Kamyanske, Dnipro area. Beta-radioactivity of the studied medicinal plants varied in the range from 1.18×10-5 Bq to 19.09×10-5 Bq at relatively clean habitats and from 18.35×10-5 Bq to 82.95×10-5 Bq on the anthropogenically polluted area. In a relatively clean habitat, the lowest indicators of beta-radioactivity in aboveground organs are characterized by Artemisia vulgaris L. and Capsella bursa-pastoris (L.) Medikus, the highest – Hypericum perforatum L. and Achillea submillefolium Klokov & Krytzka. In the underground organs, the highest indicators of beta-radioactivity were recorded in Artemisia vulgaris and Hypericum perforatum, the lowest – in Melissa officinalis L. and Valeriana officinalis L. Under conditions of industrial pollution, the lowest indicators of beta-radioactivity in aboveground organs were found in Artemisia vulgaris and Matricaria recutita L., in underground – in Tanacetum vulgare L. and Achillea submillefolium. The highest values of beta-radioactivity in these conditions were registered in the aboveground organs of Tanacetum vulgare and Hypericum perforatum and in the underground parts of Melissa officinalis and Hypericum perforatum. The analysis showed that the anthropogenic factor (pollution) has a statistically proven effect on the beta-radioactivity of the studied medicinal plants (with a probability of P = 0.999). Indicators of the strength of influence were high – from 67 to 85%. Anthropogenic pollution has the greatest impact on the beta-radioactivity of underground organs. The identified trend reflects a well-known natural dependence – the farther along the transport chain from the root is the body, the less, as a rule, it accumulates radionuclides. The detected values of beta-radioactivity, including in the industrially contaminated area are not dangerous with a single use of the studied medicinal plants. However, medicinal plants collected in the contaminated area due to increased beta-radioactivity can cause damage with prolonged systematic use due to the cumulative effect and are therefore not recommended for use.

Stable colonization of native plants and early invaders by arbuscular mycorrhizal fungi after exposure to recent invaders from the Asteraceae family

Arbuscular mycorrhizal fungi (AMF, Glomeromycota) are globally distributed symbionts of plant roots. Relationships with arbuscular mycorrhizae can provide crucial support for the establishment of any plant in an unfavorable environment. We hypothesized that invasions of neophytes are associated with changes in the colonization of native plants and early invaders (archeophytes) by AMF. We examined changes in AMF colonization in yarrow Achillea millefolium, wild carrot Daucus carota (native plants), tansy Tanacetum vulgare and false oat-grass Arrhenatherum elatius (archeophytes) in response to the invasion of four neophytes from the Asteraceae family, namely great globe-thistle Echinops sphaerocephalus, New York aster Symphyotrichum novi-belgii agg., annual fleabane Erigeron annuus, and Canada goldenrod Solidago canadensis. We found that the AMF colonization of the Asteraceae neophytes was high in the studied monodominant invasions, and the AMF colonization of the neophytes was higher than or equal to that of the studied native plants and archeophytes. Changes in plant dominance did not serve as predictors of the extent of AMF colonization of the native plants and archeophytes despite the invaded plots being associated with strong changes in the availability of primary and secondary mineral nutrients. The absence of a response of AMF colonization of native and archeophyte plant species to the invasion of neophytes suggests that AMF are passengers, rather than drivers, in the course of Asteraceae invasions in central European environments.

STUDY OF THE ANTIHELMINTH PROPERTIES OF COMMON TANSY IN HETERACIDOSIS AND CAPILLARIOSIS OF TURKEYS

The helminthic diseases of birds are widespread and cause great economic damage. Deworming of birds is one of the effective measures to combat them. For these purposes, mainly chemical synthesis preparations are used. It is established that some plants have antiparasitic properties, among them − Tanacetum vulgare L., widely spread in natural agrophytocoenoses of the Republic of Belarus. Antihelminthic properties of this plant have been studied during heterakidosis and capillaryosis disease of turkeys. Experience in studying parasitocidal activity of powder from the inflorescences of Tanacetum vulgare L. was conducted on turkeys spontaneously invaded by capillaries and heterakids. It was found out that this preparation is an effective antihelminthic remedy providing complete release of turkeys from nematodes.
