Uptake and translocation of buspirone in higher plant cultures
 Schmidová, Anna ; Smrček, Stanislav (advisor) ; Petrová, Šárka (referee)
This bachelor thesis is devoted to the phytoextraction of the anxiolytic buspirone from a cultivation medium and to the study of the effect of plant stress on the plant metabolism. Two experiments were carried out with maize (Zea mays) grown hydroponically in a sterile medium for 10 and 14 days. After the addition of a solution of medium containing buspirone at concentrations of 10 and 5 mg · L-1 , samples of medium were collected at 1-day intervals from all experimental plants. The decreasing concentration of buspirone in the medium was monitored by reversed phase HPLC/UV at a wavelength of 240 nm. In the first experiment with 10 mg · L-1 as the initial concentration of buspirone in the medium, a 65 % decrease was observed over the 96 hours during which the phytoextraction was carried out. The overall decrease in buspirone concentration was 53 % in 144 hours of phytoextraction in the second experiment with an initial concentration of 5 mg · L-1 in the medium. After the completion of the phytoextraction experiments, the activities of total peroxidases, membrane-bound peroxidases, guaiacol peroxidase and ABTS-peroxidase were determined in the leaves and roots of the plants. Furthermore, the content of phenolic substances, which belong to the group of so-called secondary metabolites and their effects...
