Rapid quantification of acetylsalicylic acid using HPLC chromatograph
Levínská, Lucie ; Kastner, Petr (advisor) ; Mokrý, Milan (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Chemistry and Drug Control Candidate : Lucie Levínská Supervisor : PharmDr. Petr Kastner, Ph.D. Title of diploma thesis : Rapid quantification of acetylsalicylic acid using HPLC chromatograph In this work, a simple method of quick assessment of acetylsalicylic acid with the use of high-performance liquid chromatograph (HPLC) equipped with an UV detector set to the wavelength 265 nm was described and validated. The mobile phase was composed of methanol and water in the ratio 10:90. The temperature was set to 25řC, injection 10 µl and the flow rate adjusted to 0.3 ml/min. The method was validated by the following parameters of validation - linearity: r = 0.9999, accuracy: 100.88 % yield and repeatability: standard deviation 1.01%. The resulting values of validation were compared with the validation parameters of a method using a typical spectrophotometer. It was proved that both methods provide reliable results. However, the analysis with the use of HPLC proved to be quicker and simpler.

Reflection of kashrut on the Passover holidays
Levinská, Lucie ; Nosek, Bedřich (advisor) ; Biernot, David (referee)
The master thesis "Reflection of kashrut over the Passover holidays" deals with fundamental questions regarding kashrut and endeavors to illustrate matters connected with dietary laws in the wider historical framework of Jewish religion, to explain basic principles of kashrut, and to explore the ethymology of specialized expressions unique to Jewish dietary law. Similarly it is explaining principles of Passover, for which I translated Rambam's writing Hilchot chametz u-matzah. Further it deals with Seder preparations and clarifies Passover customs and traditions. The last chapter shows the differences in customs between Ashkenazic and Shephardic communities. The information was sourced from both traditional and modern texts.
