Thymus alternans is a relatively new species for Romania, being first mentioned in Romanian flora in 2002. The species is quite similar to Thymus pulegioides L., shows hairy stems on opposite sides, alternating from one node to another, leaves are oblong elliptical, ciliate on margins, 2-4 pairs of lateral veins weak prominent and hairy calyx tube. The species grows in mountain meadows at low altitudes (500-1100 m). In this paper, the chemical variability of essential oils and also, their antimicrobial activity wa...

The purpose of this study is to determine the volatile organic compounds, which are responsible for the flavor found in sour cherry distillates from various regions, in order to create a comparative study, i.e. to determine criteria used in their qualitative evaluation. In fruit distillates, a big number of volatile organic compounds has already been determined. The characteristics for differentiating the different kinds of distillates are based on the major differences of relative concentration of the compound cl...

This work has pursued the accumulation process of aromatic compounds such as esters in three varieties of Romanian native wines from Apoldu de Jos, namely Feteasc? regal?, Feteasc? alb? and Iordana, obtained by fermenting them in a microvinification system, in a bioreactor equipped with temperature sensors for pH and CO2. The pectolytic enzymes Enozym flavors (3g/100 kg) and selected Vinartis ferm yeasts as Saccharomyces cerevisiae strain were used for the alcoholic fermentation. To identify and quantify the ester...
