Comprehensive sterol and fatty acid analysis in nineteen nuts, seeds, and kernel

Original language description

Consumption of nuts and seeds is considered to have many beneficial health effects, as lowering cholesterol, incidence of cancer, or enhancement of immunity system. Among the most important lipid constituents of oils present in nuts and seeds are fatty acyls in lipid classes and phytosterols. The aim of the study was to quantify wide profile of fatty acids and phytosterols in 19 nuts, seeds, and kernel commonly available in the Czech Republic. Samples were extracted by the modified Folch procedure. Fatty acid analyses were conducted by gas chromatography.The sterols were derivatized and subsequently measured by H PLC-MS/MS procedure allowing for the separation of isobaric compounds including sterol Delta 5-Delta 7 isomers. Nuts and seeds contained predominantly oleic (18:1n-9) and linoleic (18:2n-6) acids, rich sources of a-linoleic acid (18:3n-3) were linseed, chestnut, walnuts and hempseed, the last being the best source of stearidonic acid (18:4n-3). The phytosterol analyses revealed majority of beta-sitosterol and campesterol with the exception of pumpkin and melon seeds, rich in Delta 7 sterols, which were separable from Delta 5 isomers. Correlation of sterols and fatty acids content revealed positive correlation between monounsaturated/saturated fatty acids (16:1n-9, 18:1n-9, 20:1n-9, 20:0) and stigmasterol and negative correlation between fatty acids (16:1n-9, 18:1n-9) and sitostanols. In summary, our study revealed the wide profile of fatty acids and phytosterols between different nuts and seeds. Further studies are needed to confirm the positive effect of each nut and seeds for health.
