| Summary: | Charles University Faculty of Pharmacy in Hradec Králové Department of Analytical Chemistry Candidate: Michaela Majorová Supervisor: Doc. RNDr. Dalibor Šatínský, Ph.D. Title of the diploma thesis: HPLC in nutraceuticals analysis of chlorogenic acids A new UHPLC method was developed and validated for determination of chlorogenic acids and their di-substituted derivates in nutraceuticals and the developed method was used for determination of chlorogenic acids in nutraceuticals Kilostop (Astina Pharm, a.s.), Zelená káva Extra (Medicura natural), Maxivitalis Zelená káva (Simply You Pharmaceuticals), Vieste Zelená káva Premium (Volt Retail), Zelená káva bylinný extrakt (Topvet), Zelená káva (VITO LIFE) a Kyselina chlorogenová (VITO LIFE). The analysis was performed on the Ascentis Express® RP-Amide (100 x 2.1 mm; 2.7 µm) column using gradient elution program with mobile phase consisted of mixture of acetonitrile and 5% aqueous solution of formic acid at flow rate of 0.9 ml/min, the PDA detector wavelenght was set at 325 nm and the column temperature was 30řC. Keywords: UHPLC, chlorogenic acid, green coffee extract, RP-Amide column, nutraceuticals
