Abstract

Description of the subject: Allium triquetrum L. is an edible plant belonging to the genus Allium, very rarely studied. Objective: In the present study, mineral content and lipid fraction composition of A. triquetrum bulbs have been undertaken. Methods: Ash was obtained by incineration and the concentration of minerals and trace minerals were determined by using Ion Chromatography and Atomic Absorption Spectrometry. Gas Chromatography-Mass Spectrometry was used to analyze the lipid fraction extracted by the petroleum ether. Results: The results showed that ash content is equal to 4.75 ± 0.05 %. In addition, mineral content determination revealed the presence of potassium (1249.75 mg/100g), calcium (155.65 mg/100g), magnesium (105.70 mg/100g), phosphate (1249.50 mg/100g), sulphate (470.15 mg/100g), chloride (197.65 mg/100g) and iron (144.55 mg/100g) with low amount of sodium (80.30 mg/100g). The bulbs contain also zinc, copper and manganese with small levels. Lipid extract analysis revealed the presence of fatty acids (saturated, monounsaturated and polyunsaturated fatty acids) which hexadecanoic acid was the most component, hydrocarbons (n-tetradecane, n-octadecane, n-tricosane, 1-hexadecene), sulfur compounds (trans-propenyl-methyl disulfide 1,3-dithiane Methyl-trans-propenyl-disulfide) and other substances (Phenol, 2,4-bis (1,1-dimethylethyl) 4-(3,4-dimethoxybenzylidene)-1-(4-nitrophenyl)-3-phenyl-2-pyrazolin-5-one,14-B-h-pregna, neophytadiene). Conclusion: The results of this study showed that bulbs of the spontaneous A. triquetrum are very rich in minerals, trace elements and several other compounds that can be used in food and pharmaceutical applications.
