Raabová, Karin ; Karlíčková, Jana (advisor) ; Martin, Jan (referee)
CHARLES UNIVERSITY PHARMACEUTICAL FACULTY IN HRADEC KRÁLOVÉ DEPARTMENT OF PHARMACEUTICAL BOTANY AND ECOLOGY Title of the Diploma thesis: ELLAGITANNINS - OCCURENCE, METABOLISM AND EFFECTS ON HUMAN BODY Candidate: Bc. Karin Raabová Supervisor: PharmDr. Jana Karlíčková, Ph.D. Diploma thesis 2016/2017, pp. 77 Ellagitannins belongs to a class of hydrolysable tannins, which are susceptible to hydrolysis to give ellagic acid in the digestive tract. Ellagitannins occur in many plant families, for example plants in the family Rosaceae, Myrtaceae or Lythraceae. There are naturally found in some fruits (pomegranate, strawberries, blackberries, raspberries, grapes), but also in the seeds of walnuts and thus form a diverse group of bioactive polyphenols with anti-inflammatory, antitumor, antioxidant and antimicrobial activity. Special instrumental methods (HPLC, DAD, MS) are most often used for subsequent evidence of occurrence of these compounds in plants and their identification. This diploma thesis is a literature review, which aimed at processing the available knowledge about the ellagitannins. Attention was focused on the biological activity demonstrated in an animal or human organism. Keywords: ellagitannins, occurrence, metabolism, effects, human body

Plants as source of isoflavonoids
Raabová, Karin ; Karlíčková, Jana (advisor) ; Vytlačilová, Jitka (referee)
CHARLES UNIVERSITY IN PRAGUE PHARMACEUTICAL FACULTY IN HRADEC KRÁLOVÉ DEPARTMENT OF PHARMACEUTICAL BOTANY AND ECOLOGY Title of the Bachelor thesis: PLANTS AS SOURCE OF ISOFLAVONOIDS Candidate: Karin Raabová Supervisor: PharmDr. Jana Karlíčková, Ph.D. Bachelor thesis 2014/2015, pp. 65 Isoflavonoids belong to the low molecular weight secondary metabolites of plants produced by many plant families, particularly plants of the family Fabaceae. They are a common part of the human diet (peas, beans, soybeans) and have many biological effects, such as the estrogenic and antioxidant effects, but also can exhibit larvicidal activity. To subsequent establish the presence of these substances in plants are most often used special instrumental (HPLC, MS, DAD) or immunological (ELISA, RIA) methods. This thesis is a literature review, which aimed to gather information about plant sources of isoflavonoids. Among their significant sources of the Kingdom Plantae belong for example Pueraria, Dalbergia, Astragalus, Belamcanda and Gynerium. Keywords: isoflavonoids, plants, biological activity, identification
