Grulichová, Hana ; Vítová, Eva (referee) ; Vespalcová, Milena (advisor)
This bachelor thesis is engaged in the modern method of extraction PSE (pressurized solvent extraction). There have been two types of this apparatus, One PSE and Fast PSE. In this thesis, the apparatus and its behavior is described. Extraction of anthraquinones, strychnine, berberine, glycyrrhizin, ligustilides from medical plants is presented below. These substancies are used mainly in treatment for various diseases. In this work is noticed trace elements, tocopherols, alkylbenzene sulphonate, isoflavone, dionine, betacarotene, vitamin E, polyphenol extracted from biological samples. Utilization of the substancies from biological samples is very different. Some one decreased risk of osteoporosis, cardiovascular disease, cancer and other is by contrast deleterious toxin. High attention is devoted to substancies presented in food such as polychlorinated biphenyls, various pesticides, lipids, oxysterols. These substancies are in food rather undesirable than is why their amount is determinated to the food isn´t deleterious.
