| ABSTRACT: Extraction conditions are an important factor in the process of obtaining bioactive compounds from plant matrix. These compounds differ structurally. Structures of phyto-compounds and their interactions with other food ingredient are not fully known, while these two aspects should play a significant role in extrahents choice and determination of extraction process conditions. Mulberry (Morus alba) is a plant growing in Asia, which fruits are rich in bioactive ingredients and high anti-oxidative potential. In our study we analyzed mulberry fruits extracts differing in the extra hent applied: acetone, methanol, ethanol and water. All tested extracts possessed rich polyphenolic composition and radical scavenging ability. The significant differences... |

| ABSTRACT: The aim of this study was to examine the impact of cultivar and spear color on the composition of polyphenols in asparagus spears (Asparagus officinalis). The five genotypes (Schwetzinger Meisterschuss, Huchel’s Alpha, Gijnlim, Grolim and Eposs) and three growing conditions of asparagus spears (Asparagus officinalis) were investigated. The polyphenols were determined by applying the HPLC-DAD system. The obtained results were subjected to the principal component analysis. Among the analyzed asparagus samples cv. Grolim contained the highest amounts of phenolic acids and flavonols. The varied quantitative and qualitative composition of polyphenolics resulted most probably from changes occurring during vegetation, such as a lack of access to light... |

| ABSTRACT: The white mulberry leaves are typically available on the market in dried or encapsulated form. It was assumed in the study that appropriate drying of leaves of the white mulberry is significant for obtaining intermediate products with high content of compounds having anti-oxidative activity. The purpose of the study was to determine the influence of the temperature of mulberry leaves air drying on the content of phenolic acids and flavonols. It has been determined that the content of these compounds in the leaves depended on the drying temperature. Drying at 60 °C favored release of phenolic acids and flavonols from complexes and/or formation of new compounds. Their total content was 22% higher than in leaves dried at 30 °C. Drying at 90 °C... |
