“…The components with antimicrobial properties are often concentrated on poplar bud exudates [ 15 ]. Some reports showed that poplar extracts can act synergistically enhance the action of some antibiotics [ 43 ]. Antimicrobial activity of poplar components depends on the species, geographic region, and season [ 29 , 30 , 44 , 45 , 46 , 47 ]; therefore, reports on their antimicrobial activity may vary according to the source.…”

Black poplar buds have high contents of many compounds with therapeutic potential, which are useful in cosmetics and the treatment of various dermatitis, respiratory diseases, etc. The aim of this study was to identify and exploit the local plant resources with biologically active properties from the Dobrogea area, Romania. For this purpose, materials were collected from the mentioned area, and macerates of black poplar were prepared in order to evaluate their qualities as antioxidant and antimicrobial agents. Three different black poplar buds’ hydroalcoholic macerates were analyzed by the Folin–Ciocâlteau method to estimate the total content of phenolic compounds, by the HPLC-DAD method for identification and quantification of the main bioactive compounds and by the DPPH radical scavenging method to evaluate the antioxidant activity. All hydroalcoholic macerates showed high concentrations of phenolic compounds, the main individual compounds being gallic acid, chlorogenic acid, cinnamic acid, and methyl gallic acid. The antioxidant activity of the black poplar buds’ hydroalcoholic macerates, evaluated by the DPPH radical scavenging test, showed high values, between 496 and 1200 mg GAE /100 g d.w. The Cd, Cu, Zn, Ni, and Pb concentrations released in dry poplar buds, determined by AAS, were below the detection limits. Hydroalcoholic macerates of black poplar were tested against two groups of gram-positive bacteria (Enterococcus and Staphylococcus) using an agar well diffusion assay. The in vitro inhibitory activities of the macerates were important and ranged from 8.2–9.4 mm inhibition zones (Staphylococcus) to 8.6 −10 mm inhibition zones (Enterococcus).

In this article I presented the rheological behavior of corn oil studied in the temperature range 40-100°C and shear rates between 3.3 and 1312.0 s-1. The experiments showed the decrease of dynamic viscosity with temperature and shear rate. To study the dependence of dynamic viscosity on temperature, we applied two equations that perfectly describe the rheological behavior of corn oil. These equations are the Andrade equation and the Azian equation for which the correlation coefficients have values close to unity.

The rheological behavior of corn oil can be studied with four rheological models found in the specialized literature. The rheological behavior of corn oil can be analyzed if it is subjected to an increasing shear rate. The behavior of this fluid can be appreciated based on the experimental data, graphically representing the variation the shearing stress with the shear velocity. This curve represents the mathematical model of the rheological behavior of the product. The rheological behavior of the corn oil was analyzed with the mixing rheometer type Viscotester VT 550 (Haake).
