Abstract

Fatty acid profiles of 14 Linum species was determined by GC-MS analysis to study the nutritional quality of Linum species based on fatty acid composition, lipid health indices, and chemometric approaches. L. lewisii and L. marginale found to have the highest content of ALA i.e., 65.38 % and 62.79 %, respectively, L. tenuifolium recorded the highest linoleic acid content (69.69 %), while, L. catharticum recorded highest oleic acid (27.03 %). Health indices viz. polyunsaturated fatty acids/saturated fatty acids ratio, n-6/n-3 fatty acids ratio, atherogenicity, thrombogenicity, oxidability, oxidative stability, hypocholesterolemic/hypercholesterolemic fatty acids, and peroxidisability calculated based on the fatty acid composition revealed that all the linseed species except L. aristatum, L. tenuifolium and L. hudsoniodes have healthy fatty acid composition. L. lewisii clearly emerges as a promising species followed by L. bienne with great values across multiple indices, making them as a potential candidate for dietary or nutritional interests. The lipid profile of Linum species could be well distinguished by two principal components by Principal Component Analysis (PCA).
