Alkaloid isolation from Fontinalis antipyretica Hedw.
Malá, Marie ; Martin, Jan (advisor) ; Kašparová, Marie (referee)
Marie Malá, Isolation of alkaloids from Fontinalis antipyretica, thesis, Charles University in Prague, Faculty Of Pharmacy in Hradec Králové, 2012, 55 pages. The thesis Isolation of alkaloids from Fontinalis antipyretica, deals with quantification and isolation of substances of alkaloid character from above mentioned moss. The plant material collected in different localities in Czech Republic was extracted with methanol. The extract was subesquently used for isolation of alkaloids by HPLC method. The obtained amount of β-Carboline alkaloid was 2,4mg. The results of HPLC analysis (retention time, spectrum) of this sample were compared to harmalol standard and found the same. Finally the H NMR analysis proved, that the substance obtained by this experiment is not harmalol, but someother β-Carboline alkaloid.
Alkaloid and flavonoid content in Fontinalis antipyretica Hedw.
Ptáčníková, Lucie ; Martin, Jan (advisor) ; Tůmová, Lenka (referee)
Lucie Ptáčníková, The volume of alkaloids and flavonoids in Fontinalis antipyretica, Thesis, Charles University in Prague, Faculty of Pharmacy in Hradec Králové, thesis tutor: PharmDr. Jan Martin, PhD., Hradec Králové, 2012, 55 pages. Thesis called "Content of alkaloids and flavonoids in Fontinalis anitpyretica" establishes alkaloids and flavonoids and identifies one substance of these alkaloids in the above-mentioned water moss. The main purpose of this thesis was to obtain samples of Fontinalis antipyretica from selected locations in the Czech Republic (Ledce, Rychnovek, Kunvald). Next purpose was to determine alkaloids and flavonoids of collected material, isolated one substance of alkaloid character and verify identity of selected alkaloid. The content of alkaloids and flavonoids was determined by using the high-performance liquid chromatography (HPLC). The results show that β - carboline alkaloid harmin was determined by consensus UV spectrum and retention time with standard. Consequently flavonoids called myricetin and hyperosid was determined. Identity of β - carboline alkaloid harmin was verified by using NMR analysis. Keywords: alkaloids - harmalol - harmin - Fontinalis antipyretica - flavonoids
