Authenticity of natural plant component in cosmetics products
Kubalová, Michaela ; Fialová, Lenka (oponent) ; Němcová, Andrea (vedoucí práce)
The purpose of this thesis was to study the authenticity of selected natural ingredients in cosmetic products. These were specifically cosmetic products that contained citruses, mint or lavender. Commercially available isolation kits were used for DNA isolation. The presence of plant origin DNA was verified by PCR method using primers specific for the ITS2 region of plants. The presence of limonene, a significant allergen contained in said plants, was determined in the samples by PCR method using primers for limonene synthase. At the same time, its presence was verified by HPLC method. In addition, two primers were tested for lavender and monitored for their efficacy, with no significant difference in the usage.
