Interest presents its polyphenolic and carbohydrate composition and its non-polar components in the aerial parts and roots have been identified. There are no studies about the composition of the fatty acid phytocomponents in the flowers of the dandelion. The main purpose of the present study is a comparative investigation of n-hexane, ethanol, and n-hexane/ethanol (1:1 v/v) soluble compounds from dandelion flowers (Taraxacum officinale Weber ex F.H. Wigg.) collected during the flowering period. The GC-MS analysis of the non-polar (lipid) fractions showed the presence of 30 biologically active phytocompounds. The fatty acids predominated in the investigated extracts [(50-60 % of total ion current (TIC)], followed by triterpenes (9-11 % of TIC) and phytosterols (7-8 % of TIC). Polyunsaturated fatty acids-linoleic acid and α-linolenic acid (10-15 % of TIC) were identified as the major components. Phytosterols were mainly represented by β-sitosterol (3-4 % of TIC) and stigmasterol (above 2% of TIC), while pentacyclic triterpenes from cycloartenol 3-acetate (3-4% of TIC) and β-amyrin (above 2% of TIC) were found. Based on the fatty acid profile, the nutritional indices directly correlated with the lipid metabolites profile responsible for human health were calculated: Index of atherogenicity (IA)-1.2-1.6; Index of thrombogenicity (IT)-0,6-0,7; Hypocholesterolemic/hypercholesterolemic (HH) ratio-1.0-1.3; Health-promoting index (HPI)-0.6-0.8; Unsaturation index (UI)-72 and linoleic acid/α-linolenic acid (LA/ALA) ratio-1.1. The current results reveal the nutritional potential and health benefits of edible dandelion flowers.

found in ethanol extract from C. acantifololia All. roots. Three phenolic acids (chlorogenic acid, ferulic acid, and salicylic acid), three flavonoids (rutin, hesperidin, and quercetin), and triterpenes (lupeol and betulin) were detected in all samples (mainly in roots). However, p-coumaric acid
and ursolic acid were detected only in C. vulgaris, while carlina oxide was found only in C. acantifololia All. roots. The result showed that the roots of C. acanthifolia All. were characterized by appreciable amounts of total fructans (20 g/100 g dry weight), while inulin represented 18-12 g/100 g of dry weight. Sugars were found in all plant materials. The current study provides data about the chemical composition of extracts obtained from three members of the Carlina genus and their use as a source of antioxidants, phenolic compounds, carlina oxide, and inulin-type prebiotics.
