Use of NMR in structural analysis

This Diploma work is consecrated to structure determination of unknown substances. The Department of Pharmaceutical Botany and Ecology, Faculty of Pharmacy in Hradec Králové isolated number of alkaloids from three plants: Zanthoxylum nitidum (Roxb.) DC (Rutaceae), Corydalis cava (L.) Schw. et Koerte (Fumariaceae) and Zephyranthes robusta Baker (Amaryllidaceae). Some of thath alkaloids were analyzed in Laboratory of structure and interactions. The goal of this project was to determinate the structure of three unknown product, using NMR. NMR experiments (1 H NMR, 13 C NMR, ghmqfcops, ghsqc, ghmbc) were necessary to reveal the structure of unknown compounds
