Abstract The aim of the present study is to identify medicinal plants used for decorative purposes by the local population along the Northern Black Sea coast (Bulgaria). A survey was conducted in the period 2014-2020. The interviews with the local population were conducted “face to face” with the help of pre-prepared original questionnaires. The surveyed locals are 709 people from 32 settlements. Respondents were randomly selected. They are of different age groups, gender, ethnicity, education and employment. The folk names of the used medicinal plants are recorded. The results show that a significant proportion of respondents (52.89%) use medicinal plants for decorative purposes. The medicinal plants used for decorative purposes by the locals are 73 species, belonging to 61 genera from 30 families. The present study is part of a larger ethnobotanical study of medicinal plants in the region of the North Black Sea coast.

Abstract During the period 2019 - 2020, a study was conducted on soil type calcic chernozem with Kolorit triticale variety. The experiment is based on the block method, in four replications with a size of the experimental plot of 10 m2. Sowing was carried out in October with a sowing rate of 500 sprouts/m2 after the predecessor sugar beet. In the appropriate periods, treatments were made in 4 variants: 1) Control - untreated variant, 2) Treatment with biodynamic preparations: 500 + Fladen preparation + preparation 501, 3) Treatment with biological preparations: Heliosulfur + Free N, 4) Combined treatment with the same biodynamic and biological preparations. Preparation 500 was applied in the phase of autumn and spring triticale tillering - 5% solution. Preparation 501 was applied in the phase of ear formation - 1.5 g for 30 l of water/da. Fladen preparation was applied in the phase of autumn and spring tillering - 1.5% solution. Heliosulfur was applied in the ear formation phase - flowering at a dose of 50 ml/da, on an appropriate date on the biodynamic calendar. Free N was applied to the soil in the phase of autumn and spring tillering at a dose of 50 ml/da, on an appropriate date on the biodynamic calendar. The analysis of the technological qualities is made according to the respective ISO methodology. The statistical data processing was performed with the STATGRAPH program. The application of biodynamic and biological preparations and their joint use leads to an increase in the content of Nitrogen-free Extracts, an increase in the content of Minerals and Ca in the variant treated with a combination of biodynamic and biological preparations. Treatment with biodynamic preparations has been shown to increase the dry matter and organic matter content of the grain, while when compared to the control one, a difference in the same indicators has been observed only in the second year of the experiment with biological preparations. Treatment with biodynamic and biological preparations and their joint use did not affect the content of N, P and K.

The application of biodynamic and biological preparations and their joint use leads to an increase in the yield of wet gluten, as well as an increase in the content of N, P, K and protein in wheat grain. It has been proven that the combined use of biodynamic and biological preparations increases the content of dry matter, organic matter and the content of nitrogen-free extracts in wheat grain. The content of crude proteins has been shown to increase only in the varieties treated with biodynamic and biological preparations.

Abstract The understanding of the ecological behavior of Arbutus unedo L. in the context of its valuation is the objective assigned to this work. Two different observation sites were selected in Tamalous forest (Skikda) presenting different habitat contexts along a north-south transect. The methodological approach adopted is that of the comparative analysis of the physico-chemical and biological characteristics between a soil under cover of Arbutus unedo L. and bare control soil. The results obtained highlighted quite significant differences between the soils covered with strawberry tree, show that they are acidic in nature, an increase in the rate of organic matter, of the CEC which increases significantly as well as the concentration of exchangeable cations. As for the soil fauna, we observe a clear increase in biomass than in density at the level of all families of individuals, in particular the stations under the strawberry tree cover.

Abstract The aim of this study was to evaluate the effects of variety and extraction system on the physico-chemical and sensorial characteristics of olive oils produced from three dominant varieties of Algeria (Azeradj, Chemlal and Sigoise). The olive oils were extracted by three different processes (pressure system, two-phase centrifugation and traditional process). Physicochemical parameters including free acidity, peroxide value, absorbance in ultra violet (K232, K270, ΔK) and sensory evaluation were studied. The results show that free acidity, peroxyde value and K270 were influenced by the extraction system and variety. Olive oils obtained from the two phases centrifugation and Chemlal cultivar were characterized by higher oxidative stability. Sensory characteristics of olive oils were mainly influenced by the variety and extraction system. Olive oils obtained from the two phases centrifugation, traditional cold process and Sigoise variety were characterized by the lower mean values of negative attributes.

Abstract This investigation was aimed to study the effect of Pinus halepensis aqueous bark extract and zinc to prevent indomethacin induced gastric ulcer in rats. Thirty female albino Wistar rats were divided into 6 groups of 5 animals each (n=5); Group 1: normal control, Group 2: ulcer rats received normal saline, Group 3: ulcer rats treated with P. halepensis, Group 4: ulcer rats were treated with zinc, Group 5: ulcer rats were treated with P. halepensis + zinc and Group 6 ulcer rats were treated with Ranitidine for 15 days. Stomach ulcer was induced by a single oral administration of indomethacin (30 mg/kg). Various biochimical, physiologic and histologic parameters were estimated. Obtained results show that the ulcer index, pH and total acidity level were significantly reduced (p<0.05) and Pepsin activity was significantly increased (p< 0.05) in ulcer induced rats pre-treated with extract of P. halepensis, zinc and ranitidine when compared with indomethacin treated rats. The MDA level was significantly decreased and GSH level was increased (p< 0.05) in rats treated with plant extract and zinc. Histopathology of gastric mucosa confirmed the gastro-protection by plant and zinc treatment. The study reveals anti-ulcer and antioxidant properties were observed in bark aqueous extract of P. halepensis groups with a benefic effect of zinc to reduce oxidative stress and gastric ulcer induced in the rat.

Abstract The purpose of this study is to evaluate the condition of a collection of Bulgarian common wheat varieties under ex situ controlled storage after a ten-year period. The studied materials are characterized by high vitality, without negative changes that will lead to the loss of original germplasm. The established moisture in the seeds is high for the purpose of controlled storage. When it rises above 12,5%, a decrease in the values of germination energy is observed. Higher control of initial moisture and germination is required prior to entering the seeds for storage under ex situ conditions.

Abstract The aim of the study was to investigate in vitro potential antioxidant and hepatoprotective effects of methanolic extracts from the aerial parts of Matricaria pubescens, Centaurea incana, and Santolina africana, against carbon tetrachloride induced liver damage in rats. The different aerial parts of three methanolic extracts, exhibited antioxidant activity in the DPPH free radical (IC50, 0.032, 0.087 and 0.044 mg/ml) respectively. The reducing ability of the extracts showed a dose-dependent trend increasing with increase in the concentrations of the extracts.The antioxidant activity of samples at the concentration of 2 mg/ml was reflected in their ability to inhibit the bleaching of β-carotene. Treated groups with extracts of studied three plants showed decrease in plasma levels of AST, ALT, ALP, and an increase in plasma catalase levels activities, while hepatic MDA decreased and catalase increased as compared to carbon tetrachloride treated groups. In consistency with in vivo and in vitro results, extracts of all three plants ameliorated the carbon tetrachloride extensive damage to liver tissue of treated animals, but, Santolina africana extract was the most efficient.
