    Application and properties of selected flavanones
    (Wydawnictwo Politechniki Łódzkiej, 2018) Błazińska, Paulina; Sykuła, Anna
    Flavanones, secondary plant metabolites, are one of the main group of flavanoids. They are widely spread in nature in many plants. The large diversity of structural structure of flavanones and controlled methods of modifying their molecules have a huge impact on biological activity. The present review will summarize the current knowledge about occurrence, obtaining by chemical synthesis, application and bioactivity of flavanones. Also, they are received from specific chemical synthesis. Flavanones have a great biological activity. Derivatives of flavanone have many different properties such as anti-inflammatory, anticancer, antioxidant, antimicrobial or hepatoprotective activities. These natural polyphenolic compounds are used in cosmetology, pharmacy and medicine. The demand and usage on them increases.

    Antioxidants as a defensive shield in thyme (Thymus vulgaris L.) grown on the soil contaminated with heavy metals
    (Lodz University of Technology Press, 2016) Kubalt, Kamila; Leszczyńska, Joanna
    The objective of this study was to investigate the effect of excessive concentration of selected heavy metals - nickel, copper and zinc on aromatic plants Thymus vulgaris. The present work examines the concentration of phenolic compounds, total antioxidant capacity and flavonoids content in leaves obtained from plants Thymus vulgaris grown on the soil contaminated with different concentration of these heavy metals. It was assumed, that selected metals, playing the role of micronutrients, cause toxic effect in their excessive concentrations, inhibit the growth and development of plants. Adverse impact on the plant is most likely due to the oxidative stress at a cellular level. It was demonstrated, that the lowest applied concentrations of heavy metals lead to the increased antioxidant content, which then decreases with increasing metal concentrations.
