EXTRACTION AND IDENTIFICATION OF SECONDARY METABOLITES FROM SIBERIAN GROUNDSEL. Authors: . |
||||||
Abstract: Siberian groundsel (Ligularia sibirica (L.) Cass) contains many volatile compounds, pyrrolizidine alkaloids and eremophilane sesquiterpenes. This study focuses on the identification of some semi volatile and nonvolatile secondary metabolite components of from this plant, by using liquid and gas chromatography with mass spectrometry detection (LC-MS and GC-MS). From the root extracts has been identified one preudoguianolide compound by LC-MS method, in addition one guianolide and one germacrene sesquiterpene by GC-MS method. Leaf extracts analyses have been not resulted identification of any compounds. Keywords: Ligularia sibirica, mass spectrometry, fragmentation mechanism, eremophilane sesquiterpenes, pyrrolizidine alkaloids |
