Mint is one of the essential oil-producing plants. Essential oils of Mentha spicata L or spearmint are widely used as raw materials in the food, beverage and pharmaceutical preparations industries. The main components of spearmint are karvon, limonen, cineol, dihydrocarvol, myrcene, and 0.5% menthol. The components contained in spearmint have properties as herbal remedies. Plant cultivation greatly determined the results of standardized drug ingredients. Cultivation with the right planting system can affect the quality of simplicia. This research were a descriptive study to differentiate the quality of plants. This study aimed to determine differences in plant morphology, chromatogram profile and levels of spearmint essential oil between hydroponic and conventional planting systems. Observation of plant morphology includes the size, color of the stem and leaves. Essential oil content is calculated from refined oil by steam and water distillation method. Spearmint oil was analyzed on thin layer chromatography methode using the silica gel F254 as a stationary phase and hexane-ethyl acetate (8: 2) as a mobile phase, with spot visualization under UV254 and anisaldehyde-H2SO4 . The results showed that the morphology of Mentha spicata L with hydrophonic  planting systems had a bigger size in stem and leaves, but the leaves had more bright green than a conventional plant. The chromatogram profile did not show differences in the number of spots and Rf. Mentha spicata L with conventional planting systems had a sharper intensity of color on one of the volatile oil spot, and suggested  due to menthol. The levels volatile oil of Mentha spicata L hydroponic and conventional were determined as 0.0326% and 0.0323% . The Independent T-test analysis  showed that there were not a significant differences.

Abstract. The purpose of the research was to study the quality of Elsholtzia stauntonii Benth. raw materials grown in the foothill zone of the Crimea. In the course of the research, we studied such indicators as the content of essential oil and other types of biologically active substances (BAS), which allow using elsholtzia as an essential oil, food, or medicinal raw materials. Research methods. Determination of the quality of E. stauntonii raw materials was carried out according to generally accepted methods. Results. Peculiarities of the accumulation of essential oil in various organs of E. stauntonii were determined. The variability of the mass fraction of essential oil, its component composition and BAS depending on the plant’s growth stage is shown. We found that the main oil-synthesizing organs of E. stauntonii are leaves and inflorescences. The largest amount of essential oil (1.82 %) was obtained from inflorescences. In the fractional composition of raw materials, they amounted to 45.6 %. The maximum amount of essential oil with the dominant components (rosefuran and rosefuran epoxide) accumulated in plants during the phase of mass flowering (1.48 % in terms of absolutely dry weight). The highest content of BAS, namely phenolic compounds, accumulated in the stage of active growth of vegetative and the formation of generative organs of plants (regrowth and bud formation); extractives – in the stage of regrowth. During two years of storage of air-dry raw materials, there is a loss of essential oil as a result of its evaporation (54.0 %) and a change in its component composition (an increase in monoterpene derivatives of furan by 26.6 % and a decrease in sesquiterpene hydrocarbons by 23.5 %). To store air-dry raw materials of E. stauntonii for more than two years is not, however, reasonable because of significant losses of essential oil. Scientific novelty. The quality of raw materials of E. stauntonii variety Rozovoe oblako, which was grown in the foothill zone of the Crimea, was studied for the first time. Raw materials and essential oil of E. stauntonii have a broad spectrum of biological activity and can be used in medicine, as well as in essential oil and food industries.

AbstractThis study was aimed to determine the effect of different boron doses (boron free, pure boron with 8 liters per decare and in 1/8 ratio diluted boron) on the rate and quality of volatile oil in musk grown in Kütahya-Gediz conditions. Essential oil from Musk Sage was obtained by hydrodistillation method (GC-MS/FID). In the analysis carried out in 2017, the rate of essential oil was found to be 0.11% in the plant grown without boron, while it was 0.44% in the plant grown with pure boron. However, this rate was found as 0.23% in the 1/8 boron ratio application. The main components of volatile oil were found as follows: for the boron-free application—spathulenol 23.75%, caryophyllene oxide 19.41%, linalool 10.10%, and sclareoloxide 9.92%; for the pure dose application—spathulenol 26.67%, sclareoloxide 18.81%, and caryophyllene oxide 16.13%; for in 1/8 ratio diluted boron dose application—spathulenol 24.82%, sclareoloxide 16.68%, and caryophyllene oxide 14.86%. It has been observed that pure boron dose has a positive effect on the essential oil ratio and components of Musk Sage.

The Impact

The impact of nutrition area on Thymus vulgaris L. accumulation of essential oils in dry raw materials (Thymiherba) was studied and described in the article. Four schemes of cultivation were chosen to be studied: 45×40 cm — 56 thousand plants/ha, 45×30 cm — 74 thousand plants/ha, 45×20 cm — 111 thousand plants/ ha, 45×10 cm — 222 thousand plants/ha. It was shown that the increase of nutrition area helped to increase the content of essential oils in dry raw materials. Dry thyme grass with the highest content of essential oil 21.3 ml/kg was obtained when variants with the largest plant nutrition area were applied (the schemes of cultivation 45×40 cm — 56 thousand plants/ha). Reduction of the nutrition area decreased the essential oil content. According to the scheme of cultivation 45×30 cm (74 thousand plants/ha) content decreased to 20.8 ml/kg, and for the minimal nutrition area 45×10 cm (222 thousand plants/ha) the content of essential oil was 18.5 ml/kg. It was confirmed that main part of the essential oil in the raw thyme is contained in leaves, flowers and small sprouts. At the same time the woody stems contain essential oil only in trace amounts. According to the cultivation scheme 45x10 cm (222 thousand plants/ha) the leaves contained 34.2 ml/kg of essential oil, when the stems only 2.1 ml/kg. When the area of plant nutrition was increased the quality of raw materials slightly improved — for the scheme of cultivation 45x30 cm (74 thousand plants/ha) leaves contained 35.9 ml/kg, stems — 2.1 ml/kg of essential oil. The content of essential oil in the leaves was the highest — 36.2 ml/kg while using the scheme with maximum researched plant nutrition area 45×40 cm (56 thousand plants / ha). The efficiency of four norms of basic mineral fertilizers application was investigated: N0P0K0, N60P60K60, N120P120K120 and N180P180K180. It was found that increasing the rate of fertilizer application increased the yield of dry raw thyme and the content of essential oil. The most effective rate of fertilizer application is N180P180K180, which provided a dry leaves yield of 2.48 t/ha with an essential oil content of 38.2 ml/ha.The results showed that with the increase of the number of plants per unit area, the share of leaves in the total mass of raw materials decreased from 52.3% to 45.1%, but due to a significant increase in plantation productivity, dry leaf yields increased. The highest productivity was recorded for the variant of cultivation schemes 45×10 cm with a planting density of 222 thousand plants/ha, where the yield of dried thyme leaves was 1.52 t/ha.

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.
