Analytical characterization of fatty acids present in seed oils by gas Chromatography-Mass spectrometry and qualitative determination of various phytonutrients in dandelion plant

摘要

The current research was carried out to determine the phytochemicals constituents in the species of dandelion.Quantitative screenings of fatty acids was also carried out in our lab. Derivatives of methyl ester of fatty acidswere analyzed. The analysis was carried out using gas chromatography coupled to mass spectrometer. Theresult of 19 different fatty acid components were identified and quantified. Linolenic acid was found in highestconcentration (C18:2, 19.88%) among the identified analytes of interest. In addition quantification of methylesters of Tridecanoic acid (C13:0, 1.37%), Palmitic acid (C16:0, 3.89%), linoleic acid (C18:2, 7.78%) andBehenic acid (C22:0, 1.25%) were determined. Concentrations of rest of the detected fatty acids were less than1%. From the literature it appears that no such work has been performed for the determination of fatty acids inDandelion seed oil. All these plants were collected locally.
